Specifications
The AGM Sealed VRLA Battery has a nominal voltage of 12V and a nominal capacity of 9AH. Its dimensions are 151mm (L) x 65mm (W) x 93.5mm (H) with a total height of 99.5mm. The battery weighs approximately 2.55kg and can handle a maximum discharge current of 127.5A for 5 seconds. The internal resistance is approximately 17 mΩ, and it uses a T2 standard terminal with an ABS container material.

Constant-Voltage Charge
For cycle applications, the initial current should be limited to less than 2.25A. 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 0.054A for at least 3 hours. 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 2.25A.

Operating Conditions
The nominal operating temperature range is 25±3°C (77±5°F). The discharge temperature range is -15 to 50°C, the charge range is 0 to 40°C, and the storage range is -15 to 40°C. 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 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.
