Specifications
The AGM Sealed VRLA Battery has a nominal voltage of 12V and a nominal capacity of 3.6AH. Its dimensions are 134mm in length, 67mm in width, and 61mm in height, with a total height of 67mm. The battery weighs approximately 1.3kg and has a maximum discharge current of 42 mΩ. It uses a T1 standard terminal and is made from ABS container material.

Constant-Voltage Charge
For cycle applications, the initial current should be limited to less than 0.9A. 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 0.0216A 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 0.9A continuously. The temperature compensation coefficient is -18mV/ºC.

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. The battery should be charged 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 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.
