Maintenance Free Battery

“Maintenance-free” batteries have revolutionized the automotive industry, but the term can be misleading. While these batteries do not require regular water refills, they still need proper care to ensure optimal performance and longevity.

The key advantage of maintenance-free batteries is their sealed design, which minimizes water loss and extends lifespan. This is achieved through advanced grid alloys, such as calcium or silver-calcium technology, reducing self-discharge and enhancing durability. However, routine checks are still necessary—keeping the terminals clean, securing the cables, and ensuring timely recharging can prevent unexpected failures.
