Specifications
The GEL Sealed VRLA Battery has a nominal voltage of 12V and a nominal capacity of 140AH. Its dimensions are 341mm (L) x 172mm (W) x 281mm (H) with a total height of 287mm. The battery weighs approximately 43kg and can handle a maximum discharge current of 1,350A for 5 seconds. It has an internal resistance of approximately 4.6 mΩ and uses M8 standard terminals. The container material is ABS with a UL94-V0 rating.

Constant-Voltage Charge
For cycle applications, the battery should have an initial current limit of less than 27.0A. Charging should continue until the battery voltage reaches 14.1V to 14.4V at 25ºC (77ºF). The voltage should be maintained until the current drops below 0.81A for at least 3 hours. The temperature compensation coefficient for charging voltage is -30mV/ºC. For standby service, the battery should be held across a constant voltage source of 13.6 to 13.8 volts with a current limit of 27.0A continuously. The temperature compensation coefficient here is -18mV/ºC.

Operating Conditions
The nominal operating temperature range is 25±3°C (77±5°F), with a wide operating temperature range from -20ºC to 55ºC. It is important to charge the battery within 6 months of storage to prevent permanent capacity loss due to sulfation.

Performance Characteristics
The battery's capacity is affected by temperature, with 103% capacity at 40°C (104°F), 100% at 25°C (77°F), and 86% at 0°C (32°F). The cycle life is related to the depth of discharge, and the battery's float life is influenced by temperature.
