For battery maintenance and storage information, please read the following: For the ACG2500 Series UPS: Maintenance and Battery Storage The proper storage of UPS batteries cannot be overemphasized.

Improper battery storage is the most common form of battery misuse. All batteries exhibit a loss of charge over time even when stored in an open circuit condition. This is called self-discharge. Both chemical and electrochemical reactions within the battery cause this consumption of the stored energy. The self-discharge reaction rate increases as a function of temperature.

If the batteries are stored long enough without a periodic replenishment of charge, an irreversible loss of battery capacity can occur, causing premature battery failure. All Acumentrics battery packs are shipped fully charged. They should be stored separately from the uninterruptible power supply and used on a FIFO (First In, First Out) basis. All battery packs should be recharged before use of the UPS (uninterruptible power supply) if 100% capacity is required. The stored battery packs should be kept on a maintenance program and should be recharged periodically according to the recommendations shown in table 1. Battery packs can be recharged using the UPS (uninterruptible power supply).

Table 1: Storage Temperature and Supplementary Recharge Intervals The battery OCV (Open Circuit Voltage) can be used as an indicator of battery pack residual capacity. When measuring the OCV, the battery pack should not have been charged or discharged within the past 24 hours. A supplemental recharge should be performed if the battery pack OCV is 24.6 volts or less when measured at 25ºC (77ºF).

The ACG26BP has a recharge time of 2-hours to 90% present capacity from full discharge. The ACG2500BP has a 4-hour recharge time to 90% present capacity from full discharge.

Charging the UPS Battery The UPS (uninterruptible power supply) charges its battery when connected to utility power. For best results, charge the battery 4-hours before use of the UPS.
