Lead Acid Batteries vs. Calcium Batteries: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on January 28, 2024
Lead acid batteries use a lead-dioxide cathode and a sulfuric acid electrolyte, while calcium batteries replace some lead with calcium, enhancing longevity and reducing water loss.

Key Differences

Lead acid batteries are made up of plates of lead and lead dioxide, submerged in a sulfuric acid solution. The chemical reaction between these components produces electricity. In contrast, calcium batteries are a type of lead acid battery where a portion of the lead is replaced with calcium. This alteration results in different chemical properties and behaviors in the battery.

Lead acid batteries, due to their traditional design, often require regular maintenance, including water top-ups to compensate for water loss during electrolysis. Calcium batteries, on the other hand, are designed to reduce water loss. The inclusion of calcium results in a lower rate of self-discharge and water evaporation, thus they are often termed as 'maintenance-free' batteries.

The charge and discharge rates of lead acid batteries are generally reliable, but they are susceptible to degradation if overcharged or deeply discharged frequently. Calcium batteries, with their modified composition, have improved resistance to corrosion and overcharging, which in turn enhances their cycle life and reliability in various applications.

Lead acid batteries are widely known for their cost-effectiveness and high availability. However, they pose environmental concerns due to the lead and acid they contain. Calcium batteries, while slightly more expensive, offer benefits in terms of reduced environmental impact and better performance characteristics, such as lower gassing and reduced water loss.

Lead acid batteries are commonly used in vehicles, backup power systems, and for energy storage in off-grid power systems. Calcium batteries, being more resistant to heat and having a longer shelf life, are often preferred in high-temperature environments and in applications where minimal maintenance is a priority.
