Revive dead laptop battery

We buy laptop for our daily life and office work. When we show a demo or PPC for our customers or work on non power supply rooms with laptops. We also worry about its laptop battery. As the all laptop battery have their life, after charging for about 600-800 cycles it cant work, we call them as “dead laptop battery”. When we have no latitude d630 battery replacement, we try to revive dead laptop batteries.

In fact revive dead laptop battery is simple work. You can use some physical methods to activation the dead battery cells. Usually you can revive dead laptop battery using familiar tools. You only need a refrigeratory, a locked bag, a charger. Then do the following works step by step. You shall revive your dead laptop battery.

• First put the dead laptop battery in a zip lock.
• Then put the zip into refrigeratory and keep it in freezer for 14 - 15 hours.
• Afer waitinf for a long time, take the dead laptop battery out of refrigeratory .
• Using clean and soft cloth to dry the battery and get the battery to room temperature (about 20° - 25°)
• In the end fully charging and discharging the battery for 3 - 4 cycles.
• Now you would see that your dead battery holding up charge for 1-2 hours.
• See the detail video in metacafe.com

What are you waiting for, why not take a try to your dead laptop battery? Good luck. Also Hack the 6 Cell battery and 9 Cell battery difference is freezer time.

I am planning to buy some solar panels for my cabin and i want to be able to store the electricity. what kind of batteries should i get? i will be running simple things like a tv and radio. where can i buy these batteries? where should i look for the best batteries?

If you will be storing them outdoors, you can use auto batteries. Indoors, use sealed marine batteries.

Number and size depends on your needs. You will need a charge controller between the solar panels and the batteries to get the maximum power out of the array and to avoid damage to the batteries.

And you will need an inverter to convert the 12 or 24 volts to 120 or 240 VAC.

One large lead acid battery will supply about 1000 watt-hours of energy, enough for 200 watts for 5 hours. You have to look at your loads and decide on how many batteries you need.

Frequently it is cheaper to buy new appliances that use less power, as that power difference can save a lot of money in batteries, inverter, charge controller and solar panels. But it sounds like a few thousand watt-hours will be enough, 1 or 2 large batteries. The real limiting factor is how much money you want to spend for the solar panels themselves.

.

Your camcorder can become useless if its battery has no power. Here are some tips on how to conserve <a href=”http://www.needbattery.com”> camcorder battery </a> power to make it last as long as possible. Always ensure to charge your camcorder battery as camcorder batteries can lose charge when they have been stored for a long period of time. Charge the camcorder in the night even if you stored the battery at full charge.
The LCD screen are extremely power hungry. Try to use the viewfinder instead of the LCD screen as LCD screen uses more than twice the battery power than your camcorders viewfinder. If you can, compose and frame your shots using the viewfinder that does not require as much power.
Another way to save the camcorder battery power is by not using electronic or optical image stabilization. If you do not use image stabilization, you will be forced to use good videotaping techniques, such as tripod.
When you turn your camcorder ON and OFF and zoom in and zoom out a lot of battery power can be used. If you zoom, and turn OFF your camcorder when you are going to stop recording for a while, you can save the battery power. To maximize the battery power, don’t use the zoom. Instead, physically stop the camcorder and walk closer to your image and start shooting again. Yet, if you have to zoom, do not zoom much. Get your shot and stay with it.
The camcorder light that is powered from your <a href=”http://www.needbattery.com”> camcorder battery </a> can consume more battery power. So it is better to use a camcorder light that is powered from its own power supply or battery. You can also save battery by rewinding or fast-forwarding your tapes to the desired location with your camcorder plugged to the AC power supply, before you leave your house.
Having an additional long life battery is the easiest way to ensure that you have enough battery power for important events. Also keep your original battery charged as a spare for emergency situations. If you have two camcorder batteries, you can constantly charge a battery with an additional external battery charger and can always have use of your camcorder with the other battery.
Watch the event you have just recorded afterwards. In this way you can save your camcorder battery power for recording more events.When using the camera, recording videos with the camcorder, or watching videos, keep an eye on the battery icon and charge it when necessary.
The capacity of the camcorder battery also varies with different brands. Some people prefer Original Manufacturer Equipment (OEM) battery because they feel safer with it. Other people would prefer to go with an aftermarket version, which are less expensive than the OEM battery and in most cases they have a higher capacity. So before you choose your camcorder battery do your research and make sure to buy the one that satisfies your needs and the one with more capacity.
Once the life of your camcorder battery has ended, you must dispose it properly. Don’t throw it in the garbage. Bury it or cremate it as they are not bio-degradable and they can explode in extreme heat conditions. You can also recycle them with the help of online sites or even local stores that accept batteries for recycling.

Do you remember that time when you were expecting an important phone call or that SMS from your friend. Or you are stuck in traffic and try to browse the internet .. and you phone screen shows the Low Battery Sign. Damn irritating isn’t it?

Well I myself end up on a low battery on my phone and curse myself when the phone switches off ..

We all charge our mobile phones daily or once in a couple of days .. Well that is the battery life of most phones in the market. Sometimes you mightforget to charge your mobile phones and you might not have access to a charger.

I wrote this Guide so that you can Survive on Low Battery for a longer duration.. Your phone would eventually die due to lack of power but some tips to help you squeeze that last electron from the Lithium Ion Cell ..

1.Dont Use Vibrator/Silent Mode choose Meeting mode instead

The Vibrator on the phone is nothing but a motor .. you are going to be consumer more power using it ..
Meeting mode on that other hand consumes less power as it just displays the alert and a small beep.

2.Reduce Display Brightness

Many phones give you the ability to change this setting .. Set it at the lowest possible value ..

3.Dont use Speakerphone

Avoid using Speakerphone /Handsfree as they tend to consume more power ..

4.Close Unwanted Applications

More apps means more processor activity .. what app do you want to use when you can barely make a call or send a message .. act wisely

5.Stop the Music

Music via the ear phones or via speaker is a battery drainer .. Even earphones is fine .. Speakers are a absolute No in times of crisis ..

6.Camera and Video Recording

Don’t turn on the Cam unless you want to kill the battery instantly ! if you have flash then its worse ..

7.Turn off Wi-Fi Bluetooth and Infrared

These 3 are one the fastest routes to empty your battery … Refrain from using them .. If you need to use a Bluetooth Headset .. opt for a corded headset instead .

8. Turn Off when there is Poor Network Coverage / Roaming

If you keep searching for a Network when coverage is poor you are constantly draining your battery ..
Better turn of your phone or put it in Offline/Airplane Mode (new phones have this feature)
When you are travelling and are on Roaming .. you might drain battery faster ..
I saw it happen on a Train journey recently ..

9.Avoid calls from Moving Vehicles

Make calls when the Vehicle comes to a halt .. When youre moving your cellphone keeps switching towers .. so it might consume some extra power ..

10.Avoid playing games

Mobile Gaming is fun but its also drains the battery .. Games like snake are fine .. But if you’re playing NGage games on a low battery ..the fun might not last long ..

11.Close and Avoid unwanted Data Connections

if you have configured to download emails every 10 mins then disable it ..
Data connections such as GPRS and EDGE which are used while browsing or downloading use the Modem in the phone which is power hungry ..

12.Talk Less Message more

Keep your calls short .. and if needed convey the information via SMS ..

13.Lower Ringtone volumes or best .. mute it

Most users have the ringtone volume as maximum and the ringtone is so loud ..
This in turn consumes for power .. Keep your ringing volume and all alert tones at 1 or below ..

14.Switch off and turn on after few hours

This is not magic .. When your phone is ON , is consumes power and in turn drains the battery .. When you turn if OFF then the power is not drained rapidly .. note that most phones have a standby time and this tip will work only for short periods of inactivity ..

15.Other Options

Well if nothing above works for you , the you can try one of the options below .

• Carry a spare extra battery so that you can swap them when needed .

• Some public places might have a Charging Station like at Railway stations and Airports .. be careful at such places and dont leave your phone unattended .

• Carry another phone ( But remember to charge it )

• The best possible way to make the most out your mobile phone battery is by charging it regularly before it drains completely . Also carry a charger with you if you are travelling.

Batteries provide the lifeblood of most uninterruptible power supplies (UPS) and power protection solutions (some are powered by flywheel energy storage devices but most contain batteries). They provide protected loads with continuous energy in the event of a mains failure, which will support loads whilst a generator or alternative power source starts up or provide enough time to gracefully shut down equipment or ride through short duration power cuts.

Often, external battery ‘strings’ or ‘sets’ (a collection of additional UPS batteries, in blocks, providing extended runtime – runtime over and above that supported by the UPS’s own internal battery) constitute a large part of an uninterruptible power supply. A whole battery string, however, is only as good as its weakest battery. It is, therefore, imperative to regularly test UPS batteries and battery strings for ‘weak links’, which should be immediately replaced – even if they have not quite fulfilled their design life, which for UPS batteries is five to ten years.

There are various methods for electrically testing UPS batteries:

• Automatic battery set testing (by the UPS itself).
• Load bank discharge testing or battery set, string and individual cell testing.
• Electro-chemical testing.

Many uninterruptible power supplies are designed to test their batteries every 24 hours and will sound an audible alarm if a battery fault or condition is detected. How it works is that the test places a load on the battery set and the discharge performance is monitored. This is a basic type of test, however, and cannot be relied upon to give detail - other than an overall indication of the state of a battery set. Battery sets usually age uniformly but individual blocks of batteries can fail earlier than others and be rendered unable to sustain a reasonable level of charge, which can bring the whole set down under load conditions.

A more accurate and reliable way to test batteries or battery sets is to use a load bank, which places a load on the set from which measurements can be taken intermittently to assess its discharge performance. But even this has its limitations. The disadvantages of load bank testing are that it reduces resilience whilst the system is being tested, which for critical applications like hospitals or financial processing is unacceptable.

For large battery sets, individual block testing is much more reliable and need not take up additional man-hours as it can be incorporated into a routine maintenance visit. It should include a visual inspection to check that battery casings are not damaged or showing signs of aging such as buckling and emission of electrolyte discharge, which can sometimes be seen around terminals and valves.

Sulphating Batteries:

Because UPS batteries employ an electro-chemical process, they can deteriorate over time (months and even years). When batteries sulphate, Lead Sulphate crystals form within their electrolyte and at plate terminals, which will reduce charging performance and prevent normal operation. They can be recovered from this state (if caught early and their degree of sulphation is not great) by being charged at a higher current for around 12 hours. But care must the taken as this process itself can generate heat. If the battery does not recover through this means, it must be immediately removed and disposed of (by a licensed engineer) and replaced.

Impedance Testing:

Impedance testing can identify battery blocks that are about the fail. As batteries age, internal resistance (restriction to the flow of ions between the positive and negative plates) increases. Impedance testing consists of applying an ac voltage, suitable for the Ah size of battery, through probes attached to the battery block terminals. Impedance (in milliohms) is measured and recorded and compared to published data from manufacturers and/or previous recordings.

Electro-Chemical Testing:

Electro-chemical testing relies on measuring the frequency response to voltage and current signals passed into the battery using probes placed on the positive and negative terminals.

Electro-chemical testing is a non-invasive method that uses the principle of Frequency Response Analysis (FRA) to compare measured data to algorithms of known battery conditions, specifically sulphate and electrolyte dry-out. This problem is the principle cause of UPS battery failure and poor performance. Although originally only available in laboratories, electro-chemical testing can now be applied to uninterruptible power supply batteries using a specially designed, portable hand-held testing unit.

As batteries are so important to an uninterruptible power supply and monitoring and testing them relatively quick and easy, care must be taken to ensure it is done with precise regularity to ensure reliability of power protection solutions. This article was compiled using information available in The Power Protection Guide – the design, installation and operation of uninterruptible power supplies (ISBN: 9 780955 442803).

laptop batteries maintenance notes

One: notebook computers do not need to charge-discharge 
three times Unless you buy a notebook computer is more than one year of product inventory, or need not do so, as the current batteries in the battery when the factory has been activated, and the batteries in the package into a notebook battery, after a time equivalent to start the test, so you get the hands of batteries, already have been activated, and again three charge-discharge process was unnecessary to increase battery depletion.

Second: the first time do not need to charge enough to charge 12 hours
This early who do not have the battery control circuit of nickel-hydrogen batteries model is applicable, but now with the wisdom of charge and discharge control circuit for the notebook battery is a joke, when the notebook computer battery is full, the charge current will be automatically cut off, even if you continue to charge 120 hours, state and there will not be changed, generally speaking, even the slowest machine charge, six hours completely filled, the remaining “charge” is just a waste of their time. It is time to get new machines should be??first rechargeable battery.

Three: the need for regular battery calibration
Strong memory effect for nickel-hydrogen batteries, which is an essential task, but for Li-ion battery, this cycle does not need to be too frequent, lithium batteries does not completely eliminate the memory effect, but has been greatly reduced memory effect, if you use the battery very frequently, then you should discharge the battery to the relatively low (about 10 ~ 15%) rechargeable, but even if the discharge machines are not open (0 ~ 1%), belong to the lithium batteries have greater depth of injury discharge, as a general rule every two months to do this kind of operation once it. If you seldom use batteries, so long as every 3 months to conduct a this kind of operation it.

Four: to carry out the battery calibration
The so-called correction, when the actual capacity of the battery and control circuit capacity not the same record, the depth of a battery charge and discharge operation, so that control circuit record so close to the actual situation of the battery, this is a true performance of the battery capacity operation rather than to enhance the capacity of the key factors here is the actual capacity of the battery, if the actual capacity of the battery control circuit than the capacity to record high, correction can increase the capacity of the battery looks, if the battery’s actual capacity than the control circuit capacity to a record low, the correction will reduce the capacity of the battery looks, please remember that correction is to make the real capacity of the battery is shown by the battery and control circuitry to eliminate the deviation between, as demonstrated capacity will increase or decrease, This is the status of the battery itself, rather than your correction determined. Correction is likely because the battery discharge when the depth of injury, but a substantial reduction in capacity.
