When UPS uses traditional lead-acid battery, the system provides boost charge optional function. If the lead-
acid battery is used, when the mains returns after an extended mains failure, the charging voltage of the
battery will be higher than the normal charging voltage, this is normal, and the charging voltage of the battery
will return to normal value after a few hours' charging.
