CSB UPS12580 F2 (CSB, Taiwan)

CSB UPS12580 F2 - sealed lead acid accumulator with VRLA/AGM technology (the electrolyte is bound in a glass fleece), product of Hitachi Chemical Energy Technology Co. Ltd., Taiwan. Very good price/performance ratio. CSB GP batteries are characterized by a high quality standard of materials and workmanship. Typical properties are cyclic resistance, deep discharge resistance. The service life is about 4 to 6 years at 50% D.O.D. In cyclic operation, the charging voltage is 14.4 V – 14.9 V (at +25°C), in standby mode, the charging voltage is 13.5 V – 13.8 V (at +25°C).

Main applications: backup power supply for control panels and sirens of electronic security systems (ESS), into electronic fire-fighting systems (FPS), into back-up power supplies (UPS), for telecom applications etc. The battery can be used, e.g. in a backup power supply AWZ 230.

* The holding charge current is dependent on the application in which the battery operates. If the battery is used in a backup power supply, this usually allows you to set the amount of current for continuous maintenance charging (usually 0,01 to 0,02C) and/or current for backup mode (after power failure, the power supply runs on the battery, after the power is re-started, the battery is charged with 0.1 C to full capacity and then charged with holding pulse current 0,01 to 0,02C).
