Q: How to charge my IBM Fru 92P1129 battery properly?

A: There is no need to charge your new IBM Fru 92P1129 battery for 12 hours for the first time use, because lithium-ion battery is with no memory effect. So you only need to charge and discharge it normally. What’s more, you should avoid recharging it till exhausting battery power, because it will bring to much damage. Therefore you have to charge it when remaining power is nearly 10-20%. Additionally, if your battery has not been used for a long time, please charge it once a month, keep the remaining power about 40% and then store it in a dry and cool environment.

Q: Is it necessary to remove my IBM Fru 92P1129 battery when connecting to the power supply?

A: In general, it will not cause any damage without removing battery when the laptop connects the power supply. The battery will not be charged anymore after it is fully charged. On the contrary, it will turn to the use of power supply system. However, when your laptop has run for a long time at high speed, you’d better remove battery out of laptop due to the internal overheating.
