Upgrade my HP COMPAQ Laptop AC Adapter from Ni-MH to Li-ion

Ni-Cd, Ni-MH and Li-Ion HP COMPAQ Laptop AC Adapter are all fundamentally different from one another and cannot be substituted unless the Laptop AC Adapter 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 HP COMPAQ Battery Finder above to find all the compatible Laptop AC Adapter 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 AC Adapter uses a Ni-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion Laptop AC Adapter 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 HP COMPAQ Laptop AC Adapter?

There are several steps you can take to help you get maximum performance from your Laptop AC Adapter:

Prevent the Memory Effect - Keep the Laptop AC Adapter 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 HP COMPAQ 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 Laptop AC Adapter 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 Laptop AC Adapter 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 Laptop AC Adapter?

HP COMPAQ Laptop AC Adapter have two main ratings on them: Volts and Amperes. Because size and weight of Laptop AC Adapter 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 HP COMPAQ Laptop AC Adapter can power 57.60 watts for one hour. If your Laptop AC Adapter runs at 20.50 watts, as an example, this Laptop AC Adapter could power your Laptop AC Adapter for 2.8 hours.
