Upgrade my HP Laptop Battery from NiMH to Li-Ion
The NiCad, NiMH and Li-Ion versions of the HP laptop battery are all fundamentally different from one another and cannot be substituted unless the laptop computer has been pre-configured from the manufacturer to accept more than one type of battery chemistry. A person needs to refer to his or her HP laptop battery manual to find out which rechargeable HP laptop battery types the laptop device supports.
If a person’s device does allow an upgrade of the HP laptop battery from NiMH to Li-Ion, a person will typically get longer run times.
For example, if a HP laptop uses a HP laptop battery model NI-MH that is 9.6 Volts, 4000mAh and the new li-ion laptop battery is 14.4 Volt, 3600mAh, then the person will obtain longer run time with the li-ion battery.
There are several steps a person can take to help him or her get maximum performance from a HP laptop battery:
Preventing the memory effect in a HP laptop battery is important. Keep the HP 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 that do not suffer from the memory effect.
Keeping the HP laptop battery clean is also important. It’s a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the HP laptop battery and the portable device.
Exercising the HP laptop battery is key. A person should not leave the battery dormant for long periods of time. It is recommended that the HP laptop battery be used at least once every two to three weeks. If the HP laptop battery has not been used for a long period of time, perform the new battery break in procedure described in most manuals.
Battery storage is important as well. If a person is not planning on using the laptop battery for a month or more, it should be stored it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage..
