The charging current of APCSURT series UPS is generally within the range of 2-8A, and this charging current is completely sufficient for the built-in battery of APCUPS to charge to 90% of the battery capacity within 4 to 8 hours. Therefore, when customers consider using external batteries to extend the standby time of UPS, it is necessary to estimate the charging time of the external battery based on the charging power of our UPS itself, so as to configure and use the battery reasonably.
