Ni-Cd, Ni-MH and Li-Ion
ACCEL are all fundamentally different from one another and cannot be substituted unless the 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 laptop device supports or use our Compaq Battery Finder above to find all the compatible 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 Ni-MH to Li-ion, you will typically get longer run times.
For example, if your uses a Ni-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion 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.
There are several steps you can take to help you get maximum performance from your :
Prevent the Memory Effect - Keep the 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 Compaq laptop 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 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 for a month or more, store it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-ion batteries will self-discharge during storage; remember to recharge the batteries before use.
What is the run time of TopPower's ?
ACCEL have two main ratings on them: Volts and Amperes. Because size and weight of 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 ACCEL can power 57.60 watts for one hour. If your runs at 20.50 watts, as an example, this could power your for 2.8 hours.
