Exide gel battery sealed GEL12-19. The battery is completely hermetic and sealed, therefore free from acid or gas leaks thanks to the recombination principle. The acid is immobilized by gel, so the battery has a high degree of eco-compatibility. Unlike conventional battery, EXIDE GEL allows 100% discharge. When used on off-road vehicles, operating machines or boats, the battery must be able to work perfectly from all points of view and withstand severe vibrations. EXIDE GEL, thanks to its robust construction coupled with the advantages of gel technology, is characterized by resistance to high vibrations. Thanks to an extremely low self-discharge, EXIDE GEL still has more than 80% of its nominal capacity after being stationary for six months - even after 2 years it still holds more than 60%. Compared to a conventional HD starter battery that loses power steadily throughout its life, EXIDE GEL starts with increased cold start performance and keeps it constantly for life. More performance and more value for money: Compared to the HD starter battery of a commercial vehicle EXIDE GEL allows a much higher number of cycles with the same levels of discharge.
