Tips & Warnings for a laptop battery
Turn the screen light down as far as you can and still see, this will make your battery last longer.
Turn off any hardware and programs that you are not using. If you do not need them on, then turn them off.
Turn your power setting down to portable/ laptop or power saver to keep your battery running longer.
Add more RAM so that there is a minimum of hard drive access.
After storing a laptop battery and re-charging, it may only re-charge for 10-15 minutes and then claim the notebook battery is fully charged, this is a common phenomenon in rechargeable laptop batteries, to overcome this simply remove the laptop battery and then re-insert it to initiate the charging process again.
Having your computer automatically run updates means that there are things continuously running when you don't need them to be.
Running CDs and DVDs while your battery is not on the charger will drain faster.
Don't play games on your computer when the battery is off the charger, it has to work harder to run all the graphics and other necessary programs.
Never connect a laptop to an automotive power supply adapter as a substitute for running on the laptop battery. You likely will damage or destroy your laptop.
Lithium Ions can be ruined if the voltage drops below a certain level, avoid letting your notebook battery drain completely and repeatedly.
If you plan on not-using the notebook battery for a month or longer then fully charge the laptop battery, then store it in a cool place. The laptop battery will lose its charge while stored and will need to be re-charged before you begin using it again.
The Do's and Don'ts of Battery Use
Fully charge/discharge battery up to 3 cycles before achieving full capacity of a new battery
Fully discharge and then fully charge the battery every two to three weeks for battery conditions.
Run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.
Remove from the device and stored in a cool, dry, clean place if the battery will not be in use for a month or longer,Recharge the battery after a storage period
Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.
Do not short-circuit. A short-circuit may cause severe damage to the battery.
Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
Do not expose the battery to moisture or rain.
Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.
Why won't the battery on my notebook charge?
The charm of a notebook computer is you can easily transport it from one location to the next. Whether you are moving the laptop from one room in your house to another or taking it on vacation with you, portability is a laptop's primary asset. However, portability becomes compromised when your notebook's battery no longer charges, because you then have to keep your computer plugged in at all times. There are three primary reasons a notebook battery won't charge, and none of the resolutions are cheap.
Sometimes the battery refuses to take a charge because the battery itself is bad. Whether it is prematurely defective or several years old, a bad battery will refuse to charge. Replacing a bad battery can be expensive, with aftermarket replacements starting around $100 as of the time of publication. If your computer is still under warranty and it has a bad battery, contact the manufacturer to find out if you can have the battery replaced under the warranty. Otherwise, use the age of the computer as well as the cost of the battery to determine whether it is worth replacing.
As with batteries, notebook motherboards can start malfunctioning with age, though some are also prematurely defective. In these cases, the portion of the motherboard that relays power from the DC jack to the battery no longer works. Unfortunately, this also requires you replace the entire motherboard. Motherboards are normally covered under manufacturers' warranties, so if your warranty is still valid, you may be able to get a free fix. If the notebook is not covered under a warranty, though, the cost of the repair is rarely worthwhile, as motherboard replacements -- once you factor in parts and labor -- often cost more than the notebook itself.
Bad AC Adapter
If your AC adapter is faulty, your battery will not charge properly. Minor internal breaks and fractures in your power cord can cause power to intermittently get to your battery, while a dead AC adapter will force your computer to run on battery power until the battery completely loses charge. The power cord is the easiest notebook part to replace, as many universal adapters are available for purchase. While a replacement AC adapter is still expensive, it is significantly cheaper than having to replace a battery or motherboard.
Troubleshooting a battery that does not charge is rarely a do-it-yourself task; without the right tools and knowledge, the only element you can test yourself is the AC adapter. You can do so by removing the battery from the notebook computer, plugging the notebook into the wall and attempting to turn it on; if the laptop turns on, your AC adapter is functional, but if it does not, the AC adapter is faulty. If your AC adapter is functional, the next step is to take your computer to a certified technician to figure out the exact reason -- or sometimes, reasons -- why your battery is not charging.
How can I maximize the performance of my battery?
There are several steps you can take to help you get maximum performance from your battery:
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 do not suffer from the memory effect.
Keep the Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.
Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.
Your battery has a different voltage to my battery, can I use it?
Different voltages stated on batteries may be compatible. For example voltages from the same pairs below, are compatible:
3.6V / 3.7V
7.2V / 7.4V
10.8V / 11.1V
14.4V / 14.8V
The capacity of your battery is different to mine, can I still use yours?
Yes. The capacity of a battery does not affect its compatibility in anyway. A higher capacity battery will simply power your device for longer before you need to charge it.
It is important to check the dimensions and weight in addition to the capacity because sometimes higher capacity batteries can be larger in size, making them impractical for some uses even though they are compatible.
