from Ni-MH to Li-ion
Ni-Cd, Ni-MH and Li-ion
are all fundamentally different from one another and cannot be substituted unless the laptop 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

Finder above to find all the compatible Laptop Battery 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 laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.
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
COMPAQ laptop battery ?
There are several steps you can take to help you get maximum performance from your laptop battery:
Prevent the Memory Effect - Keep the COMPAQ Presario laptop 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.

Battery Storage - If you don't plan on using the COMPAQ Presario laptop battery 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 power-depot.co.uk's laptop battery?
have two main ratings on them: Volts and Amperes.Because size and weight of Laptop Battery is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together.
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
can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this Laptop Battery could power your laptop for 2.8 hours.
