Difference Between Lead Acid and Calcium Batteries

16/06/2018· The key difference between lead acid and calcium batteries is that the lead acid battery has a lead electrode inside the battery whereas the lead calcium battery has calcium along with lead as the electrode inside the battery. Because of the use of lead-calcium alloy for the electrode in lead-calcium batteries, they have a low self-discharging effect and a longer service life than the lead
