GEL1270AG-CGB battery 12V7AH-gel battery for solar and wind power systems

■FEATURES

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

- GEL electrolyte inside the battery maintains uniformity, ensuring excellent cycle life.

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

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

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

- Leak-proof, safe, and reliable.

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

- Low self-discharge rate.

■STORAGE

- Batteries should be stored in a dry, clean warehouse with good ventilation. Avoid direct sunlight and proximity to heat sources (such as radiators, with a distance of more than 1 meter). Avoid contact with any toxic gases and organic solvents.

- The longest storage life is 6 months when the ambient temperature is below 25℃. If the ambient temperature is higher, the longest storage life varies as shown 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 2.1A, constant voltage of 2.45±0.05V/cell (at 25℃); charging time: 15~20 hours; temperature compensation coefficient: -5mV/℃/cell.
