EGL deep-cycle batteries are maintenance free lead-acid based battery cells specially designed for wind and solar power applications. They have long product life guaranteed to work with high charging current and under hushier temperature conditions.
The cells have thicker-than-usual erosion-proof lead-calcium-tin-aluminum alloy plates that are seperated by non-woven glass-fiber fabric known as Absorptive Glass Mat (AGM). Diluted acid is absorbed in the AGM encased in tough non-leaking ABS casing. Also available deep-cycle GEL batteries. CE safety approved.
