Specifications
The GEL Sealed VRLA Battery is designed for a long life of 12 years as per EUROBAT standards. It has a nominal voltage of 12V and a nominal capacity of 120AH. The dimensions are 333mm (L) x 173mm (W) x 216mm (H) with a total height of 223mm. The battery weighs approximately 31.8kg and can handle a maximum discharge current of 1,350A for 5 seconds. The internal resistance is approximately 4.3 mΩ, and it uses an M8 standard terminal. The container material is ABS with a UL94-V0 rating.

Constant-Voltage Charge
For cycle applications, the rated capacity varies with the discharge rate: 120.0AH at a 20-hour rate, 115.0AH at a 10-hour rate, 97.75AH at a 5-hour rate, 86.3AH at a 3-hour rate, and 69.0AH at a 1-hour rate. The initial current should be limited to less than 28.75A, and charging should continue until the battery voltage reaches 14.1V to 14.4V at 25ºC. The voltage should be maintained until the current drops below 0.69A for at least 3 hours. The temperature compensation coefficient for charging voltage is -30mV/ºC.

Standby Service
The battery should be held across a constant voltage source of 13.6 to 13.8 volts with a current limit of 28.75A continuously. The temperature compensation coefficient for charging voltage is -18mV/ºC.

Operating Conditions
The nominal operating temperature range is 25±3°C, 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, 100% at 25°C, and 86% at 0°C. The cycle life is related to the depth of discharge, and the battery exhibits specific discharge characteristics at different end voltages and durations.
