An excited news for laptop users that Hewlett-Packard will offer new “green” notebook batteries from Boston Power. The lithium-ion batteries that HP will offer can Save the Environment  and Last  for 3 years as an option on its Enviro Series notebooks can be recharged a thousand times and deliver an 80 percent charge in 30 minutes. Boston Power says the environmentally friendly batteries are also safer and can replace existing batteries.

A fast-charging laptop battery that promises to last at least three years without any degradation in performance is coming to the market as an option with Hewlett-Packard laptops. The Sonata battery is the product of three years of development work by Boston-Power and will be rebranded by HP as the “Enviro” battery and offered from early 2009 with select machines.

The battery can be charged to 80 per cent of capacity in 30 minutes, which could be useful for travellers who only have a limited amount of time near an electric outlet, and will go 1,000 charges before the battery’s capacity begins degrading. That’s a charge a day for three years — or four years if it’s only used on weekdays — so it should last the average life of a business laptop. Common laptop batteries today start to degrade after 300 charges.

“It brings a new level of performance to the market,” said Christina Lampe-Onnerud, founder and CEO of Boston-Power in an interview.

Boston Power’s lithium-ion battery can be recharged a thousand times compared to conventional batteries that can be recharged only 300 times, according to Frost & Sullivan, a consulting company.

The Sonata battery can also achieve an 80 percent charge in 30 minutes and a full charge in one hour without degrading cell performance, according to the company. Batteries currently on the market typically take as much as one hour to reach 80 percent power in a fast-charge cycle that can degrade cell performance by 60 to 80 percent within 300 charge cycles.

HP will back up its longer-life promise with a 3-year warranty and the battery will cost an extra US$20 to $30 over a standard model. Users will be able to select it with certain machines during the customization phase of ordering. It will initially only be available in North America but HP plans to offer it in other markets later.

Lampe-Onnerud first unveiled the Sonata battery at the Demo 2007 conference and the company has spent the last two years developing the technology and preparing for mass-production. Most of the batteries will be made by Taiwan’s GP Batteries while some will come from HYB Batteries in China.

At the time of its launch at Demo it was endorsed by Hewlett-Packard and the two companies have been working together ever since so HP’s move as the first major customer for Boston-Power isn’t a surprise.

Looking ahead the company is hoping to pick up addition laptop vendors as customers as well as break into other industries including consumer electronics and transportation, said Lampe-Onnerud.

For a digital camera battery, the length of using time, not only relate with the quality, power, in fact, the user’s operation also has great relevance. Most photographers are accustomed to place the camera inside the camera bags after use, or placed inside cabinets, batteries are not out to save individually, this approach sounds like no problem, but not conducive to battery protection.

Generally speaking, if you do not use the camera more than 15 days, then best to remove the battery from the camera to separate storage, preservation of the environment is best dry and shady place, and do not store the battery together with metal objects.

According to our survey, currently in the market the majority of digital cameras use lithium batteries, it is relatively easy storage. The only caveat is that if not used for a long-term, preferably at intervals of 2 months, once to activate the battery, that is, charge and discharge, this can effectively extend battery life.

As for the Ni-MH battery, the memory effect will reduce the total capacity of the battery and the using time, and as time goes on, stored charge will get less and less , the battery also will be consumed faster and faster. Therefore, we should try to recharge after power all used up, each charge must be sufficient.

If you go out and temporary use the alkaline batteries, you must remember takeing out in time, or else if not used for a long time, the battery is easy to corrupt circuit, the camera could not escape the scrapped destiny . 

For the rechargeable Ni-MH batteries and lithium batteries. For just bought back the general power is very low or no power, the first charge must be adequate. Lithium battery charging time are generally more than 8 hours, while the Ni-MH battery charging time are generally more than 16 hours. To achieve the best results, that is, the battery reached its maximum power, there are generally three or more times repeated charge-discharge. Battery tend to be more heat after charging, it is best to be cooled and then loaded camera battery.

However, note that the lithium batteries don’t have memory effect, so do not discharge, otherwise it will destroy the battery structure, and loss of battery life.

In addition, in order to avoid the loss of electricity, remove the battery after charge, do not let the battery poles in contact with conductors at the same time, for example, do not use your fingers at the same time at both ends of the battery contacts. The lithium batteries users should try to keep the camera battery box battery positive and negative contact points clean, if necessary, you can use a dry cloth gently wipe the swab and then install the battery.

A digital camera popularly known as a digicam is used for capturing video or taking still photographs by recording images via an electronic image sensor. Some other compact digital still cameras may also record sound and moving video as well as still photographs. Need not to mention that the second worst thing about digital cameras, after their price, is their battery consumption. Many digital cameras use AA cells to run and drained out in very less time sometimes less than an hour of shooting.

Since alkaline batteries drains faster than their counterpart rechargeable batteries, the biggest complaint for digital camera battery problems is that the batteries do not last long. Alkaline batteries lose their power while taking sixty to one hundred pictures however rechargeable batteries can last for two hundred to five hundred pictures in one go. Battery consumption of these digital cameras is increased as the newer generation cameras have more utilities like Image stabilization and high-powered zoom in its kitty.

So opting the rights batteries save your pocket and apart it also prevents to miss a memorable moment due to flat batteries. The most sought after batteries for the digicam are made up of lithium ions that can be charged over and over again and commonly used in most electronic gadgets. Regardless of its weight or size, it has the capacity to store more energy than other rechargeable batteries in the marketplace.

It’s an easy task to save your battery and extend its life. You need to take some little cautions while using your digital camera.

• Keep your Digital Camera Battery fully charged and then fully discharging it at least once every two to three weeks

• Always clean dirty battery contacts with a cotton swab and alcohol that enables to maintain a good connection between the battery and the portable device

• It is widely recommended that you must use the battery at least once every two to three weeks. If a Digital Camera Battery has not been used for a long period of time power of the battery may reduced

• It is a good suggestion to store batteries in a clean, dry, cool place away from heat and metal objects If it is not going to use for a month or more

• The most important thing is one should use the right kind of battery and should always clean the battery component and should always remove the battery when camera is not in use

Duracell Active Charge is a range of rechargeable batteries with low self-discharge and can instantly be used and stays charged longer than standard rechargeable batteries. Theses batteries have elevated competence levels since they have up to 40 percent longer service life than ordinary battery of same size batteries. Active charge batteries have long cycle life as they contain up to 450-500 charge & discharge cycles throughout the entire life cycle and due to zero percent cadmium existence they seem to be environment friendly.

Duracell active charge batteries have a capacity to grip added energy and their ability to be recharged at any time without any sheer memory effect. This is the basic reason Active charge battery is very popular in devices such as flashlights, digital cameras, and hybrid vehicles. Active charge rechargeable batteries come in many shapes and sizes from automobile lead-acid type batteries to laptop and small digital camera batteries. The size is determined by the type of technology used and the design of the device in which the battery will be placed.

Using a charger, these batteries can be recharged many times. These rechargeable batteries may be used in automobiles, consumer electronics storage for solar arrays and electrical vehicles. With thin construction and light materials, lithium-sulfur batteries tend to weigh less than other, similar batteries. Active charge batteries have lowered weight so provide more power than other batteries available in market. In devices like cell phones, light weight is very mandatory therefore these batteries could be a big improvement. These batteries possess an extended lifetime and increased power withholding under humid environments.

These batteries have the benefit of a higher density and higher voltage capacity than many other batteries. Intrinsic to the basic design of Lithium-ion batteries is the ability to recharge hundreds of times whilst being able to hold their charge for long periods when not in use. Active charge batteries have no harmful compounds for the environment and have no impact of memory effect in long run. As it has the capability to recharge hundreds of times rather buying a new battery every time, it is widely accepted in most applications throughout. Batteries can be recharged for hundreds of times and perform amazingly well at high temperatures. In addition, they have low-impedance design and can deliver a high rupture of current.

1. Defrag regularly -  The faster your hard drive does its work - less demand you are going to put on the hard drive and your battery.  Make your hard drive as efficient as possible by defragging it regularly. (but not while it¡¯s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.

2. Dim your screen - Most laptops come with the ability to dim your laptop screen.  Some even come with ways to modify CPU and cooling performance.  Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.

3. Cut down on programs running in the background.  Itunes, Desktop Search, etc.  All these add to the CPU load and cut down battery life.  Shut down everything that isn¡¯t crucial when you¡¯re on battery.

4. Cut down external devices - USB devices (including your mouse) & WiFi drain down your laptop battery.  Remove or shut them down when not in use.  It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.

5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory.  Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.

6. Run off a hard drive rather than CD/DVD - As power consuming as hard drives are, CD and DVD drives are worse.  Even having one in the drive can be power consuming.  They spin, taking power, even when they?re not actively being used.  Wherever possible, try to run on virtual drives using programs like Alcohol 120% rather than optical ones.

7.  Keep the battery contacts clean:  Clean your battery¡¯s metal contacts every couple of months with a cloth moistened with rubbing alcohol.  This keeps the transfer of power from your battery more efficient.

8. Take care of your battery - Exercise the Battery.  Do not leave a charged battery dormant for long periods of time.  Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)

9. Hibernate not standby - Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn¡¯t save anywhere as much power as the hibernate function does.  Hibernating a PC will actually save your PC¡¯s state as it is, and completely shut itself down.

10. Keep operating temperature down - Your laptop operates more efficiently when it¡¯s cooler.  Clean out your air vents with a cloth or keyboard cleaner, or refer to some extra tips .

11. Set up and optimize your power options - Go to ¡®Power Options¡¯ in your windows control panel and set it up so that power usage is optimized (Select the ¡®max battery¡¯ for maximum effect).

12. Don¡¯t multitask - Do one thing at a time when you¡¯re on battery.  Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3¡¯s, set your mind to one thing only.  If you don¡¯t you¡¯ll only drain out your batteries before anything gets completed!

13. Go easy on the PC demands - The more you demand from your PC.  Passive activities like email and word processing consume much less power than gaming or playing a DVD.  If you¡¯ve got a single battery charge - pick your priorities wisely.

14. Get yourself a more efficient laptop -  Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries.  Picking up a newer more efficient laptop to replace an aging one is usually a quick fix.

15. Prevent the Memory Effect - If you¡¯re using a very old laptop, you¡¯ll want to prevent the ¡®memory effect¡¯ - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.

Bonus Tip #1: Turn off the autosave function.  MS-Word¡¯s and Excel¡¯s autosave functions are great but because they keep saving regular intervals, they work your hard driver harder than it may have to. If you plan to do this, you may want to turn it back on as the battery runs low. While it saves battery life in the beginning, you will want to make sure your work is saved when your battery dies.

Bonus Tip #2: Lower the graphics use. You can do this by changing the screen resolution and shutting off fancy graphic drivers. Graphics cards (video cards) use as much or more power today as hard disks - Thanks Andrew

Update 7/7/07: Bonus Tip #1 to give caution about turning off autosave, tip #8 to change information about discharging batteries - thanks to all who pointed it out. Added Bonus tip #2, Tip #1 to add in clause in regards to Mac OSX, Tip #1 about the spinning of hard drives - thanks to all who pointed it out

Many manufacturers provided a laptop batteries calibration program, a Windows version and BIOS version, it is best to use these programs to correction,

Use the correct charger
Notebook computer power consumption is much larger than cell phones, power needs and at the same time the battery is running at full speed to meet the machine’s power supply requirements, various models of voltage, current, or even the interface is different, even the same interface, if the voltage and current lower than the nominal value of machinery, machine working at full speed when the battery may not be able to obtain sufficient charge current, which damage the battery is a great one. If the voltage and current much lower than the nominal value, or even find that simply can not boot to boot, or can not charge, please note the voltage and current machines must be in line with nominal value, with the plants of different products in general the same interface, but voltages and currents may be different, we must pay attention to this point! 

 

laptop battery does not use long-term preservation methods
Or whether it is full of??, they are actually incorrect, put long-term preservation of photoelectric batteries will lose their activity, even lead to the control circuit protection self-locking and can not re-use, full of power will bring about long-term preservation of the security problems, the most the preservation of the ideal way is to discharge to about 40% and then save, lithium batteries fear humid and high temperature, it should be placed in a cool dry place to preserve, but the temperature is not too low B, otherwise the capacity will be greatly reduced, about 20 degrees Celsius is an ideal Storage Temperature. 

laptop battery can not do so for their own batteries
The battery is a lot of people for such a deadly, manufacturers seem to expect someone to do so long ago, many brands of notebook battery design are self-locking function, once the batteries out of control circuit, the circuit enters a state of self-locking, Only the use of certain means in order to unlock, in this control circuit before will not work, that is equivalent to end-of-life batteries, notebook batteries batteries can not change the batteries, if you want to change batteries, please find a specialized battery maintenance companies to wield the sword.

 

VIII: charge can not charge to 100% of the treatment methods
Notebook batteries almost no chance of explosion, the largest is the issue of high fever caused by shells melt, but rarely lead to open flame, was released by a small number of incidents, the fact is that when the production technology of non-performing, in use led to a short circuit caused by, even if Most of this will be short-circuit the battery protection circuit in the circuit will not disconnect greater damage, unless it is in the protection of the circuit before the batteries short-circuit (notebook computer batteries should explosion is caused). It is the phone a lot of such things, in the final analysis or the quality of the battery problems, a large number of poor-quality mobile phone battery assembly, and notebook computers rarely have this kind of battery.

The reason why 99 percent to less than 100 percent after the charge is often because the battery control circuit of the records and the status of the battery itself, the deviation, the battery has not reached a record control circuit voltage, so power control circuit has been charging, in fact, battery has been replete with such problems can usually be resolved through the correction, but even if there is no correction, because the majority of charging circuit will be a long time can not be filled automatically disconnected after, or even smart record automatically refresh the current 99 percent to 100 %, even the fool has been non-stop design, but also because of the current very small at this time and will not cause injury.

The current laptop batteries are basically temperature detection circuit, when the battery temperature is too high, control circuit most mandatory disconnect the battery to prevent further temperature rise, so this kind of charge to the explosion in notebook computer batteries that occurred no less chance of the first prize in the lottery.

Car battery is the rechargeable battery that provides electric power to different components of the car. The primary function of the battery is ignition. In addition, the battery provides extra power for various electronic car components.

If the car battery plays such an integral role in the functioning of the car, then it’s very important to take good care of the battery. Seasonal checks and periodical maintenance of the car battery is crucial to enhance life of the battery as well prevent ignition blues.

Signs of Low Battery

Here are some of the signs that indicate that the car battery is either low or needs to be replaced:

• Dim headlights

• Slow Ignition

• Improper functioning of the car air-conditioner

• Spark in the electric wires

• Car electronics not working effectively

Here are top 10 tips for car battery care:

1. Firstly, it is important to keep the battery clean and free from dust. To do so you can use baking soda and a non-metallic brush to get rid of any corrosion from the cables.

2. Then, disconnect the cables and clean the area surrounding the battery terminals and cables.

3. To remove the battery cables first disconnect the negative cables and then the positive.

4. Remove the battery cover and check the level of electrolyte/ it should be about half an inch deep. If the level is not maintained add clean distilled water and let it mix with the electrolyte.

5. Inspect the battery case for any kind of leakage and cracks. If in case there is any crack replace the battery case.

6. Make sure the car battery is well secured inside insulated case because the vibrations caused while driving may damage the battery. Ensure that to protect the battery from vibrations, you don’t over tighten the clamps.

7. To replace the car battery carefully lift the battery because the acid inside can be dangerous.

8. To reinstall the cables, first connect the positive cables and then the negative.

9. Smear a little petroleum jelly onto the battery terminal before fastening the cable clamps to the posts. This jelly like substance will help slow down corrosion and enhance life of the attery.

10. These days many different types of car batteries are available. If in case you have a non-maintenance battery, check if you can see a green dot in the charge indicator. This green dot indicates that the battery is functioning effectively and if the indicator light turns yellow or no colour, it needs to be replaced.

Cell phones, also commonly known as mobile phones, are electronic devices which are used for communication purposes. Voice or data is communicated through these cell phones over a network of stations. Cell phones have all the features of a general telephone and also have various specialized features.

History and Overview:

Cellular Network was initially proposed by Bell Labs in the year 1947. He was the first person to establish cellular network in the year 1970 in Chicago. After that Japan launched the first mobile phone service in the year 1978. With the advent of time, there has been tremendous improvement in the mobile phone technology and in the year 1996, mobile phone giant Nokia launched its first multi use smart phone Nokia communicator which had the facility of internet connectivity and email services.

Cell phone handsets:

Cell phone handsets are the devices which are used for communication purposes. There are a wide rang of handsets with varying features which are being produced by manufacturers worldwide. Currently, Nokia is holding the largest chunk of market share of cell phones and is regarded as world`s largest manufacturer of mobile phone handsets.

Other major names in the list of cell phone manufacturers include Motorola, Sony Ericsson, Samsung, LG etc. These cell phones work on rechargeable batteries which obtain power from electric current, solar, dynamo, car battery charger etc. Before using a handset it needs to be activated with a SIM card provided by a mobile phone service provider who will also allot a unique number for your phone.

Features of Cell Phones:

Apart from having almost all the features of a normal telephone the cell phone also has various other unique features which make them very useful in today`s busy life schedule. These features include music, mp3 player, in built high pixel still and movie camera, personal organizer functions, Internet connectivity with browsing and emailing facility, different ring tones both inbuilt and with a facility to download, blue tooth and infra red connectivity etc.

Cell phones are also able to receive and send faxes if it is connected to a computer. Apart from Short messaging service (SMS), Cell phones are also enabled to send pictures and videos through Multimedia messaging service (MMS).

Uses of Cell Phone:

Cell phones are now widely used by both civilians and government agencies. Government agencies use mobile phones extensively for law enforcement, military purposes, disaster management etc. In the usage of cell phones, you must be particular about maintaining the culture and customs.

It is not decent to use your mobile phone while sitting in an important meeting. It is desirable that you switch off your phone when in any funeral or libraries or cinema halls etc. Most schools and colleges have restricted the use of mobile phones in their premises.

Beliefs about health and environment hazards and safety concerns:

Several concerns regarding human health resulting as an impact of mobile phone usage has been raised from time to time. There have been dermatological concerns such as occurrence of rashes on ears and cheeks of the users, hearing problems in the ear, heart problems concern etc.

Environmental hazards such as electronic waste and safety hazards in usage of the cell phone have been of great concern. There has been an increase in accidents by drivers while talking on cell phones. Road accidents while using a cell phone are on an increase. High rise towers of the cellular networks are also a cause of concern to flying aircrafts and birds.

The tremendous benefits of connectivity in all locations wherever you are have outshined the disadvantages and health concerns of cell phone and the number of cell phone users is rising day by day.

Isn’t one type of battery better than the other? Why don’t all electronics use the better battery and which type of battery is the better battery?

NiCads are cheap and like providing a lot of current, which is why they are used in power tools and such. NiMH the same, except they require the added expense of a smart charger.

Lithium ion batteries are used in electronics to make them smaller and lighter than they would have to be with standard alkaline or rechagrable cells.
