1, How long can a new UM09A75 computer battery drive the computer?

It is difficult to determine the operation time of the laptop battery. The actual operation time depends on how much electricity is required by the device. The screen size, hard disk and other accessories may consume extra electricity and shorten the operation time. The total operation time of the UM09A75 computer battery also depends on the design of the device. Generally, a ACER computer battery of a standard volume is designed to drive the computer for more than two hours.

2, Do I have to remove the UM09A75 battery when I use the AC supply?

Answer: Generally, the charging of a ACER UM09A75 battery begins only when the electricity volume is lower than 95%. Due to existence of natural consumption, the battery consumption is basically the same no matter whether you remove the battery or not while the computer is working. However, we recommend you not to remove the ACER Laptop Battery while operating the computer because this prevents the data loss in case of abrupt interruption of the AC supply. If you remove the battery, wrap it into a fresh keeping film and put in a dry and cool place. Remember to perform a complete charging and discharging cycle for the ACER UM09A75 battery every month to prevent the battery from losing activity.
