Auto One 7612 Heavy Duty Calcium Maintenance-Free 12V Battery (HCM27L Size, 680CCA, 162RC, 97Ah)
As pure lead is not strong enough alone to withstand the operating conditions, calcium is added to the plates of these wet lead acid batteries to significantly improve the mechanical strength of the lead. Calcium is preferred over the previously commonly used antimony because of decreased electrical resistance, better resistance to corrosion, reduced gassing and reduced water usage - enabling a maintenance-free design.
