Tips to extend the life of notebook battery

There are many kinds of notebook battery,different types of batteries will certainly not the same.Now lithium-ion battery commonly used in laptop or similar products.Shortly before personal computers, A4-based notebook computers in the temporary use of the premise of using a nickel-metal hydride battery.Until the mid-nineties, using a nickel cadmium batteries.After the user has bought the notebook,first please read the operation manual,to confirm what kind of the battery,if does not have the instruction booklet,we can check the battery specifications through the home page of the notebook company.

The “memory effect” is the biggest problem of nickel-hydrogen batteries and nickel-cadmium batterie,if the battery has not run out on charge. When next time using the battery,there will be no power on that place started to charge.If circulates this process unceasingly,the battery’s life will become shorter and shorter.

Although the “momory effect” of  Ni-MH battery is smaller than nickel-cadmium battery,but the half-way charge repeated is  the reasons for shortening the life of battery.So please try to be all used up the battery before recharge.

Lithium-ion battery without the “memory effect”, so even the off half-way charging there will not be  too much a problem.

The method to extend the battery’s life.

Although the lithium-ion battery without “memory effect”, but improper use will greatly affect life expectancy. When use a lithium-ion battery should pay attention to the following points:

1,Fully charged state not to use AC power | Regulators drive;

2,Using the energy saving features;

3,Fully discharge once every few months;

4,Unplug the AC adapter,when the notebook not in use in a long period of time

For those of you who are first time DIYs, the battery is one of the integral components of your car; it is rechargeable and is the power source of the ignition system and other electrical devices in your car.

Initially there’s the maintenance free and low-maintenance types to choose from. A maintenance free battery is sealed and will not require replenishing the battery fluids over a long period of time while the low-maintenance type requires constant check up and replenishing once a drop in battery fluid levels can be seen. Battery fluid (Alkaline) can easily be bought at local gas stations and car yards or you can use distilled water as a substitute.

In layman’s terms the battery is the heart of your car but is often times the most neglected simply because nowadays it’s bought “maintenance free.”

Recent trends and technological advancements have made maintenance free batteries a standard on every vehicle out in the market today.

Don’t get the impression that since you’ve read on the label that it’s maintenance free, you will just simply put it in its place and forget about it. Your car’s battery is not entirely that. Just like any other sensitive equipment of your car, it also requires your constant care and attention for it to function well.

Here are the basic maintenance tips that will certainly save you a lot of trouble and will not leave you clueless by the roadside while on a very important trip.

As a rule before doing maintenance checks, always see to it to disconnect the clamps off the terminals to avoid untoward injuries from shock.

1. Check the cell casing and cover

Run an ocular inspection on the battery cell casing, box and cover for signs of moisture and pungent acidic smell. These are indicators that your battery is leaking and it needs to be fixed or replaced right away.
Maintain caution when handling leaking batteries for hazardous chemicals are present.

2. Clean terminals, clamps and cables

When you happened to see white powdery specks or see colorful substances around the terminals, they are signs of corrosion and needs to be cleaned right away. Make a baking soda solution (1 tablespoon baking soda immersed in 1 cup of water) and with an old toothbrush, clean the terminals, clamps and cables. Also clean the battery cover for accumulated grime and dust.

3. Make sure everything is dry

Make it a point to have everything dry before going further with your check up. With a dry rag, wipe off the remaining dew and moisture from the battery and terminals.

4. Check the wiring and connection

Run a check on the wires and clamps for strips or corrosion. If you have stripped cables, patch the affected part with a good electrical tape or have them replaced by a mechanic. Make sure that the battery is placed securely in its place. If your battery is equipped with a hold down bar, be sure to replace it.

5. Lubricate the terminals

With a lubricant (Petroleum jelly) place a small dab on the terminals. This will keep your cables clean and free of corrosion longer, while making it easier for you to put the cables back on the battery terminal.

6. Change your battery

Change your battery at the maximum of 3 to 3.5 years or after reaching the warranty period. For accidental battery drain (Such as leaving the lights on or stereo on) a lot of auto technicians would just recommend re-charging.

Car battery maintenance is that easy! Do it frequently to extend the life of your battery.

Safe driving.

A battery may count as a bit small, but in reality, it is one of the most crucial components of your car as it is the one that gives power to all electronic gadgets, components and the startup of your engine.

No matter how well maintained your car is, once you power it up with a low performance battery, it will eventually be left lifeless on the road. It is therefore important to outfit your car with the best battery around.

Recent developments of the vehicle industry has produced upgrades or modifications allowing batteries to keep up with the advanced features of models from various makers. Competition among the battery manufacturers also provides consumers with lower prices, improved battery life and more advanced features. All batteries now can be installed DIY!

Below are the simple how to’s to help you select the right battery for your car.

Finding a new battery

When looking for a new battery, always take note that prices may vary because of brand, features, quality and capacity.

If you’re looking for a brand that’s reliable, simply do a research online for the most popular or ask other car owners for the brands that they’re using.

The availability of new batteries is not a question nowadays; you can get hold of them at most car shops, service centers and auto supplies from urban areas up to the farthest countryside. Prices may vary but most shops provide discounts for customers who turn in their old batteries.

Provided you have the budget, see to it not to buy cheap batteries! You might think that you’re getting a bargain now but sooner or later, you will suffer as cheap batteries are poor in quality and will surely never last long.

Check your car manual or battery referral guides in automotive shops for factors such as group size, cold-cranking amps and cranking amps to properly guide you in your selection.

Group size- Refers to battery volume with the location of terminals (positive + and negative -) your manual indicates the group size required by your car’s model.

Cold Cranking Amps (CCA) - Refers to a battery’s ability in cold weather conditions. It is in situations such as these that the engine oil becomes thicker thereby making ignition difficult. You can tell how much electrical power your battery can provide to your car at zero degrees (F) by looking at its CCA rating.

Cranking Amps (CA) – Is the indicator of a battery’s power-capability.

Now that you know what to look for, it is then time for you to consider buying a battery based on preference leads such as:

Maintenance

You can select from maintenance free or a regular battery. I’d say go for the maintenance free type as you will not go through the hassles of constantly checking and refilling the battery electrolyte fluids.

Country climate and driving conditions

Select the battery that fits your country climate and driving condition. If you are living in a country with high temperatures, it is appropriate for you to select the battery type for a long life. Look for a tough housing that will protect the plates from easily corroding and provides protection against fluid evaporation.

Display date

Select the ones that are displayed fresh on the counter with no more than 6 months from their manufacture date.

Battery handles

For easy installation and pullout, select a battery that has a handle on it. You wouldn’t want to carry a 4-5 kilo box just by holding on to its sides now would you?

Follow these tips to land the perfect power for your ride. Drive safely.

It is difficult to predict how long a laptop battery charge will last because each computer user has different habits and needs. The rate at which you use laptop battery power will determine how long you can use the battery of your laptop. You can re-calibrate your laptop battery if the battery’s life has gotten shorter over time. Your laptop battery might need a good calibration if it doesn’t seem to be getting the mileage that it should. How to re-calibrate laptop battery? The following paragraphs will give you the answer.
First put the laptop computer to sleep by turning off the screensaver and other power management settings of the computer. Then fully charge the computer and allow it to run all the way down until the computer shuts off automatically. Once the laptop battery has fully drained, charge it back up again and restore the screensaver and power management settings.
Re-calibrate your battery every month or so by fully charging, fully discharging, and then fully charging again. Basically to have a chance to re-calibrate your laptop battery is to turn off all power-saving features completely and then fully recharge them. If it doesn’t work for the first time then try two more full discharges and recharges.
The above way of re-calibrating the  laptop batteries works well with laptops using Ni-MH cells. But not with laptops using Li-Ion batteries because deep discharges will actually decrease the charge capacity and lifespan of Li-Ion cells. Moreover Li-ion batteries irreversibly lose approximately 20% capacity per year from the time of manufacture at a typical 100% charge level at 25deg.C, even when unused. Li-ion batteries irreversibly lose approximately 2%, 4%, 15% at 0deg.C, 25deg.C and 40deg.C respectively, when stored at 40% charge level. That is every deep discharge cycle decreases the capacity of the Li-ion batteries. As the Li-Ion batteries are chemical in nature, charging and recharging is not going to fix the problem once the chemical reactions stop happening. Therefore the best advice for re-calibrating the Li-Ion batteries is to store the battery at 40% charge if it kept unused for any unlimited period of time. Also don’t leave the battery in the laptop if you don’t use the battery or if you plug the laptop into outlet power.
You can also re-calibrate your laptop battery using IBM Thinkpad Battery Maximizer in order to maximize your laptop battery’s life. If your laptop has IBM ThinkPad Battery MaxiMiser and Power Management features installed, you can verify the condition of the laptop battery. You can check the status of your battery using the Battery MaxiMiser Gauge in the taskbar tray. The ThinkPad’s Lithium Ion battery pack that seems to be an intelligent battery uses a microprocessor to monitor its capacity. Then the microprocessor of the battery pack passes the information about the remaining battery capacity to the laptop. The laptop indicates the capacity with high accuracy.
Using the HP Laptop Battery Learning Utility, a modified version of a Win98 boot floppy, can also help you. Just place it in the floppy drive, and then turn on the computer. The re-calibration process is automated and takes about six hours to finish. This utility is available in different versions for different models. You can run the utility every two months.
If the laptop battery is still bad then it must have developed a memory that cannot be erased easily. If calibration doesn’t help, then it is the right time to purchase another battery.

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.

If the charge in your laptop battery is dying out noticeably faster, you may need to replace it. Battery performance is affected by many factors like the environment, age and frequency of utilization.

Every battery has a certain number of charge cycles specified by the manufacturer and indicates the number of times you can charge it - this figure is around 400 - 1200 for a standard Lithium-ion laptop battery. Once this limit is crossed, the performance begins to deteriorate.

Depending on the devices available in the laptop and their usage, the battery might be able to power it for 2-3 hours before it needs to be recharged. Normal lifetime is in the range of 1.5 - 2 years. If you use the laptop continuously and recharge the battery several times a day; it may need to be replaced well before the time frame specified by the manufacturer.

These steps must be followed for battery replacement:

1. Buy a New Battery - Make sure you purchase a replacement that is compatible with your laptop.

2. Unpack the New Battery - Remove all packaging material and keep have the new battery ready to be popped in immediately.

3. Undock Laptop - If your laptop is connected to a docking device, you need to unlock it before attempting to replace the battery.

4. Turn Off Laptop - You may not want to lose any files you are working on or risk corruption of software, so it may be better to turn off the laptop.

5. Unplug AC Power/Internet Connection - It is a good practice to disconnect your laptop from the AC outlet, Internet and Telephone before replacing the battery.

6. Flip the Laptop Over - Most laptops have the battery release mechanism on the underside of the laptop. If you are not sure where you should look you can refer to the documentation of the laptop or have Technical support guide you.

7. Unlock and Remove Old Battery - Laptop batteries usually use a two-step locking mechanism, first there are latches that need to be released and then a sliding motion has to be performed to release it completely. Your documentation can be invaluable in this.

8. Position New Battery - Follow the reverse process for fixing the new battery. First slide and then latch the new battery. If the latches get stuck, you may need to adjust the positioning.

9. Charge Battery - Bring laptop to usual position; replace all the cables that you disconnected earlier, including the AC power. Charge your battery for the duration specified by the manufacturer before using it.

Stanford University, the newly discovered laptop battery life of up to 40 hours
Stanford University researchers has made a major discovery, notebook battery can run once a day or even longer.

     Researchers have found a way to make lithium-ion battery storage capacity 10-fold increase, which may be notebook battery life from the current 4 hours extended to 40 hours.

Cui said that the battery capacity of the increase is due to use of a new type of silicon nanowire anode. Traditional lithium-ion batteries use graphite as the anode, which limits the anode can be attached to the number of lithium ion, but also limiting the battery life.

We can thank Stanford University Assistant Professor Yi Cui and his buddies at the Department of Materials Science and Engineering for this breakthrough. Scientists have known for a long time – the article says 30 years – that silicon anodes would extend the charging capacity theoretically. But when you add lithium, the silicon anodes would change volume by 400 percent, according to the Sci-Tech Today article.

Cui and his amigos figured out the anode could hold 10 times the lithium if they used a sponge-like network of silicon

if commercialized successfully, could mean laptop battery life extended tenfold from what we know now. The breakthrough came about when researchers replaced the battery anode’s typical graphite nanowires with silicon ones. The Stanford team has filed a patent for the technology and estimates the potential two-day batteries could hit the market within several years.

Good fellas at the Stanford Tech are researching and developing a battery that will be able to keep you notebook powered for a whopping 40 hours! This new kind of lithium ion battery will be available in a few years time. Stanford Tech researchers including Professor Yi Cui and his team have brought alive an old but abandoned method for charging the batteries: Silicon anodes. These have a theoretical capacity ten times larger than that of the graphite anodes currently used, but were left for dead, as they expand up to 400 times when charged, smashing themselves in the process. However, if the silicon is made into nanowires the problem diappears.

As you walk back to your car after a night out, you realize to your horror that you left the headlights on. As expected, the battery is dead and the car won’t start. The best thing to do is to flag down a car and ask for a jump to quickly jolt the battery back to life. 

You should always keep a set of jumper cables in the trunk so you can get a jump if you need it because you never know when the battery will fail; but if tinkering under the hood isn’t your style, there are several products on the market designed to make the process easier. There are jumper cables that connect one car to another through the cigarette lighters, eliminating direct contact with the car batteries. There are also car starters that plug into the cigarette lighter and jump start the battery at the push of a button; these products are convenient because they don’t require that you rely on the kindness of strangers or that you leave the comfort of your car to jump start the battery. 

Aside from leaving the headlights on for prolonged periods of time, a car battery may fail because it needs to be replaced or because there is a charging problem due to a faulty alternator. It’s a good idea to invest in a multimeter, an instrument that makes various electrical measurements, so you can check the electricity circulating through the battery and its surrounding components. This will prevent you from replacing the battery prematurely or unnecessarily if the problem is not the battery. 

A multimeter can be analog or digital and is usually a rectangular box with two leads coming out of it; the positive lead is red and the negative lead is black. With a mutimeter, you can test the voltage of a car battery by setting the device to the volt scale and placing the positive lead onto the positive battery terminal and the negative lead onto the negative battery terminal. If you get a very low reading, you should think about replacing the battery. You can also test the fuses by disconnecting the battery terminal, setting the device to the ohm scale and placing both leads on the fuse legs. This is done to see if there’s electron flow within the fuse, which would indicate it’s working properly. And finally, you can make sure the alternator, which is part of the car’s battery charging system, is working properly by comparing the voltage in the battery when the car is off to when the car is on. If when the car is on, the voltage is higher, the alternator is working properly. Check the car manual for information about the car battery and the surrounding components. 

If you need to change the car battery, the first step is to purchase a new one. Buy the same kind of battery you currently have in your car or check the car manual for battery specifications. 

Follow these 10 steps to easily replace your car battery: 

1- Locate the battery under the hood.  

2- Disconnect the cable terminals from the battery terminals starting with the negative side. Pay close attention to the position of the battery terminals 

3- Remove the battery bracket. 

4- Clean the inside of each cable terminal with a wire brush. 

5- Place the new battery into the slot with the battery terminals in the same position as the old battery  

6- Replace the battery bracket  

7- Connect the cable terminals to the battery terminals; make sure they are tightly secured.  

8- Start the engine to test the battery.  

9- Dispose of the old battery in accordance with local laws or drop it off at a local auto parts store or recycling center.

Laptops are the necessity of the life these days because of its mobility. Well they are handy, easy to carry with you and all but what if it doesn’t have good battery? That’s true in Laptop Battery plays vital role. What if you want to use your laptop at the place where there is no ac mains power? Then you have only one option is that you must have enough battery life in your laptop.

Generally Laptop battery usually come in two types - nickel cadmium and nickel metal hydride. It’s good to know that to charge brand new batteries in cycles of fourteen to sixteen hours. The batteries should be allowed to cool down before recharging them because overcharging them will shorten their life.

Now if we think some technical points then ready access to chargers is important because nickel cadmium may suffer from a ‘memory defect’ and user may suffer with such problems if batteries are not fully discharged before recharging. A nickel cadmium battery should be charged only after it has been completely exhausted, otherwise the battery ‘thinks’ that it only has fifty percent of its original capacity and only uses half of its potential, thus increasing the time constraints of the laptop.

Laptop Batteries can be charged 2 ways, one, when the AC power is on for laptop. At that time a small flow of electricity runs to the battery which is called trickle charge. This will automatically recharge the battery after laptop is disconnected form AC supply. Second one is charging a battery with external charger.

These days Nickel cadmium batteries are most popular as they are long lasting and very efficient, and they perform more efficiently when they are fully discharged and then recharged. If a battery is used in a more piecemeal fashion then, occasionally fully discharging the battery before recharging it will enhance the productivity of the same. Some battery chargers do this automatically, but leaving the laptop during the night and recharging the battery in the morning can also invigorate the battery efficiently.
