I am planning to replace my house bank this year of about 650 amps. My boat is located in the Caribbean
so you dont get too many battery
choices out of the chandleries in the caribbean
. Vetus marine
has a line of batteries being sold at Budget marine
that touts "lighter and smaller" due to Lead/calcium grids instead of lead/antimony. Does anyone that knows batteries have an opinion on these batteries and the stated calcium technology for a house bank? I can go with lifeline AGM
but at considerable cost and weight.
Vetus Maintenance Free Deep Cycle 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.
