Product details
CSB GPL12650 is a 12V valve-regulated sealed lead-acid battery in the GPL series. The GPL series builds on the GP series with an emphasis on long life; its target application is general float standby power, enabling longer service life. It uses AGM (Absorbent Glass Mat) technology, with gas recombination efficiency up to 99%, maintenance-free; internally it has a pure lead construction combined with a proprietary formulation. The product is manufactured according to IEC 60896-21/22:2004 and recognized to UL1989 (MH14533).
In terms of life, in 25°C float standby service, the GPL12650 can last up to 10 years; under the Eurobat (20°C) standard it exceeds 12 years, placing it in the Very Long Life class. This makes it suitable for float standby power supplies, such as general-purpose standby power systems, and it operates stably under the temperature and charging conditions listed below, addressing long-life, maintenance-free backup power requirements.
Capacity data: nominal 65Ah (1.75VPC @25°C, 20-hour rate). Different discharge conditions are 63.60Ah at 8-hour rate 1.75VPC @25°C, 70.40Ah at 20-hour rate 1.75VPC @25°C, and 62.40Ah at 8-hour rate 1.80VPC @25°C. Current and internal resistance specifications include maximum charge current 19.50A, maximum discharge current 500A, short-circuit current 1637A, and internal resistance 5.3mΩ; standby power systems can manage charging and discharging accordingly.
Temperature, charging, and self-discharge: at 25°C, float voltage per unit is 13.5 to 13.8 Vdc, and equalization voltage is 14.4 to 15.0 Vdc. 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. At 25°C, self-discharge is less than 10% after 90 days, and maximum storage time is 6 months; fully charge before use, and if storage temperature is above 25°C, charge earlier.
Appearance and terminals: length 349.4mm, width 166.0mm, height 174.9mm, weight approximately 20.8kg. Terminals are I2 threaded lead alloy terminals, can accept M6 bolts, torque 51.7±10.3 Kgf·cm, i.e. 44.9±9.0 Lbf·in or 5.10±1.0 N·m. Case material is PP (UL 94-HB); a flame-retardant (94-V0) version is available on request.
