This 70Ah GEL Battery is a valve-regulated lead-acid battery with the feature of maintenance-free. This is because its electrolyte is a gel-like substance, and the internal gas is allowed to recombine into water by opening the valve in one direction, so there is no need to check whether it is filled with distilled water or monitor the water level. The battery adopts tight assembly technology to ensure leak-proof and safe design, which can improve safety and prolong the service life of the battery during long-term use. In addition, it can be safely installed in a place with limited ventilation, because its gas/smoke output is very low, and you can even install it at home.

Features:

This 70Ah GEL Battery is specially designed for deep cycle discharge, which is very suitable for applications that need frequent and long-term discharge and charging, such as solar energy storage, marine use and electric vehicles. Its maintenance-free structure allows you to use it easily without regular inspection and water addition. At the same time, it has strong heat dissipation ability, is compatible with sensitive electronic equipment, and will not cause interference or damage. And because it can provide reliable performance in countless charging cycles, it helps to reduce maintenance times and replacement costs to help you reduce costs.

Application:

1.Solar power system & Wind system

2.Deep discharge UPS

3.Outdoor energy storage systems

4.Communication systems

5.Electric power systems

6.Electric vehicles
