GEL1240AG-CGB battery 12V4AH-gel battery for solar and wind power systems

■Features

- Designed with flat plate, GEL electrolyte, and AGM separator technology.

- The GEL electrolyte inside the battery maintains uniformity, resulting in excellent cycle life.

- The GEL electrolyte has a large thermal capacity, preventing thermal runaway phenomena.

- High strength ABS material used for the container & lid.

- Wide temperature range of application (-15~45℃) with the optimal temperature being (20±5℃).

- Leak-proof, safe, and reliable.

- Can be used standing or lying down, convenient for transportation and installation.

- Low self-discharge rate.

■Storage

- Batteries should be stored in a dry and clean warehouse with a good ventilation system. Avoid direct sunlight and proximity to heat sources (such as radiators, with a distance greater than 1 meter). Also, avoid exposure to any toxic gas and organic solvent.

- The longest storage life is 6 months when the ambient temperature is less than 25℃. If the ambient temperature is higher, the longest storage life varies as specified in the table below:

  - Storage Temperature (℃)≤2526～3334～40

  - Storage Time (Month)631

- Batteries should be recharged within the storage life or before use.

- Charging methods: maximum charging current of 1.2A, constant voltage of 2.45±0.05V/cell (25℃); Charging time: 15~20 hours; Temperature compensation coefficient: -5mV/℃/cell.
