Product details
The GPL12520 has a nominal capacity of 52 Ah at the 20-hour rate, 1.75 VPC, 25°C; at the 8-hour rate, 1.75 VPC, 25°C corresponds to 49.36 Ah, and 1.80 VPC, 25°C corresponds to 48.32 Ah. 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.
This battery belongs to the CSB GPL series, its type is a 12V valve-regulated sealed lead-acid battery, and its product classification is 12V Top Terminal VRLA-AGM. The GPL series is the long-life version of the GP series, used for general-purpose float standby power; under float conditions at 25°C, design life can reach up to 10 years. The Eurobat long-life standard classifies it in the category of greater than 12 years at 20°C.
In terms of construction and materials, the GPL12520 uses a valve-regulated sealed lead-acid structure and AGM technology, with gas recombination efficiency up to 99%. It is a maintenance-free design and uses pure lead construction with proprietary elements. The case is PP (UL 94-HB); if a flame-retardant version is required, 94-V0 material can be requested. The terminal is an I2 threaded lead alloy terminal that accepts M6 bolts, with 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, length is 228.0±2.5 mm, width is 138.4±1.5 mm, height is 206.3±2.5 mm, and weight is 17.80 kg (39.23 lb). At 25°C, equalization charge voltage is 14.4 to 15.0 Vdc/battery, and float charge voltage is 13.5 to 13.8 Vdc/battery; nominal operating temperature is 25°C, discharge temperature range is -15°C to 50°C, and charge and storage temperature range is -15°C to 40°C.
Regarding self-discharge, it can be stored for up to 6 months at 25°C and must be fully charged before use; if storage temperature is above 25°C, recharge earlier. After 90 days of storage at 25°C, self-discharge is less than 10%. Manufactured in accordance with IEC 60896-21/22:2004, recognized to UL1989 (MH14533), suitable for float standby power applications.
