GFM (2V) series valve controlled maintenance free lead-acid battery

Basic Features

Product characteristics

1.Battery tank, cover: high quality ABS synthetic resin, higher safety;
2.Pole plate: high corrosion resistance of multiple lead and calcium alloy plate grid;
3.Separator: ultra-fine glass fiber separator with excellent heat resistance and oxidation resistance, prevent short circuit of positive and negative electrode plates, retain the electrolyte, press the surface of the plate, prevent the active substance from falling off, improve the deep cycle life of the battery;
4.Safety valve: the safety valve with good acid prevention performance, prevent sparks from entering the battery, and prevent acid fog from escaping from the battery.
5.Sealant: efficient sealing agent and special structure of the sealing design, to ensure that the battery will not leak defects.
6.Battery terminal: brass electroplating aluminum based alloy, good corrosion resistance, excellent electrical conductivity, high strength. The battery terminal is an embedded (built-in) terminal, which is easier to connect and install, and the battery performance is better.

Battery characteristics

Maintenance-free

No rehydration, no balanced charging

Has a long service life
At 25 operating temperature, the service life can be over 12 years.

No liquid leakage, no air leakage

Special sealing design, never produce leakage, leakage phenomenon.

Safety valve design, safe for use

Has a high energy density

High energy output power and little internal resistance.

Self-discharge is small

After the battery is fully charged, open at 25℃ for 3 months, and the capacity can remain more than 90% of the initial capacity.
