Vetus Maintenance Free Batteries

Designed especially for the rigors of marine use.
The VETUS battery has sufficient electrolyte to last the whole of its life.
A special construction with lead/calcium grids instead of lead/antimony plates reduces the water consumption considerably. The latter in conjunction with the large reserve of electrolyte means that “topping-up” is no longer required. This special construction also means that Vetus batteries are up to 25% lighter and 40% smaller than equivalent batteries. The wrought lead-calcium grids and special separators give the batteries extremely long cycle lifetimes in either starting or house bank applications.
Topping-up, “periodic cleaning”, and greasing of the connections are no longer required. You just install and forget it. Recharging can be done with a conventional battery-charger. Also the state of charge can be checked from the outside. A test indicator on top clearly illustrates this. The use of a hydrometer is eliminated.
