What Are Some Battery Maintenance and Storage Tips for my ATT 500 Unit. The proper storage of your ATT 500 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.
ATT 500 should be stored separately from the UPS and used according from oldest to newest. All ATT 500 battery packs should be recharged before use if 100% capacity is required. The stored ATT 500 battery should be kept on a maintenance program and should be recharged periodically according to the recommendations of the tabel below. Battery packs can be recharged using the ATT 500 UPS unit.
