Calcium Battery
A battery in which both grids are made of a lead-calcium alloy.
The calcium alloy has largely replaced the lead-antimony alloy that was previously used. The use of calcium reduces the amount of gas in the battery. Less liquid is lost, making closed, maintenance-free batteries possible. Calcium batteries are mostly used as starter batteries because they have a good cold start performance. They are less suitable for cyclical use, i.e. frequent charging and complete discharge, as when used as a drive or supply battery.
