Ni-Cd, Ni-MH and Li-ion Laptop Battery 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 device supports or use our HP RW557AA Laptop Battery Finder above to find all the compatible HP RW557AA 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 uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion battery is 11.1 Volt, 4400mAh, then you will obtain longer run time with the Li-ion battery.
Example.
Li-ion: 11.1 Volts x 4.4 Amperes = 48.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-ion is stronger and has longer run time.

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 HP RW557AA Laptop 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 HP RW557AA 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 HP RW557AA Laptop Battery?
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. For example:
11.1 Volts, 4400mAh (Note: 4400mAh is equal to 4.4 Amperes).
11.1 x 4.4 = 48.84 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This HP Laptop Battery can power 48.84 watts for one hour. If your runs at 24.42 watts, as an example, this HP Laptop Battery could power your for 2.0 hours.
