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 200AH. The dimensions are 523mm (L) x 239mm (W) x 218mm (H) with a weight of 59.8kg. The maximum discharge current is 2000A for 5 seconds, and the internal resistance is approximately 3.8 mΩ. The standard terminal is M8, and the container material is ABS UL94-V0.

Constant-Voltage Charge
For cycle applications, the rated capacity varies with the discharge rate, from 212.0AH at a 20-hour rate to 123.0AH at a 1-hour rate. The initial current should be limited to less than 40.0A, and charging should continue until the battery voltage reaches 14.1V to 14.4V at 25ºC. The temperature compensation coefficient for charging voltage is -30mV/ºC. For standby service, the battery should be held at a constant voltage of 13.6 to 13.8 volts with a current limit of 40.0A.

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 document includes detailed tables for constant current and constant power discharge at various end voltages and time intervals, highlighting the battery's performance under different conditions. The cycle life is related to the depth of discharge, and the capacity curve is affected by temperature.
