Product details
The CSB GPL12520 is a 12V valve-regulated sealed lead-acid battery belonging to the GPL series, with a product type of 12V Top Terminal VRLA-AGM. This series is the long life version of the GP series, intended for general purpose float standby power applications, with a design life of up to 10 years in float service at 25°C, meeting the Eurobat long life classification of greater than 12 years at 20°C.
In terms of capacity, the GPL12520 has a nominal capacity of 52 Ah (20-hour rate, 1.75 VPC, 25°C). At the 8-hour rate, 1.75 VPC, 25°C, capacity is 49.36 Ah; at the 8-hour rate, 1.80 VPC, 25°C, capacity is 48.32 Ah. The battery's maximum charge current is 15.60 A, maximum discharge current is 500 A, short-circuit current is 1485 A, and internal resistance is 5.1 mΩ.
The battery uses valve-regulated sealed lead-acid construction and AGM technology, with gas recombination efficiency up to 99%, a maintenance-free design, and pure lead construction with proprietary elements. The case material is PP (UL 94-HB); a flame-retardant version in 94-V0 material can be requested. The terminal is an I2 threaded lead alloy terminal accepting an M6 bolt, with terminal torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m.
In terms of dimensions, the battery length is 228.0±2.5 mm, width 138.4±1.5 mm, height 206.3±2.5 mm, and weight 17.80 kg (39.23 lb). For charging, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C.
In terms of self-discharge, self-discharge is less than 10% after 90 days of storage at 25°C, and the battery can be stored for up to 6 months at 25°C, requiring a full charge before use; if the storage temperature is above 25°C, it should be charged sooner.
