What types of UPS batteries are available in the computer room?

First of all, the UPS battery must be a backup battery, not a starting battery (such as used in cars);

The choice of UPS battery depends on the main factors such as UPS capacity, required backup time, use environment and expected service life.

After the above conditions are determined, the optional batteries are: sealed lead-acid battery (12V or 6V or 2V respectively) (environment-sensitive, less maintenance workload), open lead-acid battery (large capacity, long life, environment-insensitive, heavy maintenance workload), open alkaline battery (environment-insensitive, long life, heavy maintenance workload) and sealed alkaline battery (expensive, long life).
