Computer batteries are specifically designed for each computer brand and model. AtBatt.com offers a complete line of batteries and compatible replacements for most notebook computers. We have developed a KTX Computer Battery Select Technology™ that will guide you in choosing the correct battery and ac adapter for your computer. Your first step is to choose your computer manufacturer from the list below.
Upgrade my KTX Computer Battery from NiMH to Li-Ion
NiCad, NiMH and Li-Ion KTX computer batteries are all fundamentally different from one another and cannot be substituted unless the computer computer has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the computer device supports or use our KTX Battery Finder above to find all the compatible computer batteries for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from NiMH to Li-Ion, you will typically get longer run times.
For example, if your computer uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new li-ion computer battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the li-ion battery.
Example.
Li-Ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours The Li-Ion is stronger and has longer run time.
How can I maximize the performance of my KTX computer battery?
There are several steps you can take to help you get maximum performance from your computer battery:
Prevent the Memory Effect - Keep the computer 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 KTX computer 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 computer 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 computer 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.
What is the run time of AtBatt's computer battery?
KTX computer batteries have two main ratings on them: Volts and Amperes. Because size and weight of computer batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:
14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This KTX computer battery can power 57.60 watts for one hour. If your computer runs at 20.50 watts, as an example, this computer battery could power your computer for 2.8 hours.
Are there restrictions when taking lithium-ion batteries on planes? Effective January 1, 2008, the Department of Transportation (DOT) will no longer allow loose lithium batteries in checked baggage. These batteries may continue to be packed in carry-on baggage. To read more: http://www.atbatt.com/blog/31/Traveling-with-Spare-Batteries.asp
