Make your HP PB991A battery last longer:
- Should I totally discharge and recharge my HP PB991A battery occasionally to make it last longer?
A: No, discharging and charging does not increase the life of a Li-ion HP PB991A. And with current Li-ion batteries this practice does not improve the runtime of the battery. This practice is a holdover from the days in which batteries were used.
- How do I get the most runtime for a charge?
A: It is important to choose settings which allow you to obtain the most runtime from your notebook. Examples to consider: timeout settings for the hard drive, Bluetooth, wireless, LCD brightness, etc.
