How long is the lifespan of an EFB battery?

[LaSerenity]

EFB batteries have low self-discharge and a relatively long lifespan. The lifespan of an EFB battery can reach 3 to 5 years. Additionally, EFB batteries utilize new manufacturing processes, significantly improving cold-cranking current compared to conventional batteries. The lifespan of a conventional battery is typically 2 to 3 years. Beyond this period, vehicle owners should pay special attention to battery maintenance and replace it promptly when necessary to avoid affecting vehicle usage. Below is a brief introduction to EFB batteries: 1. EFB batteries are based on traditional battery technology but allow the adjustment of electrolyte concentration by adding distilled water, thereby enhancing deep-cycle performance. 2. EFB batteries exhibit excellent high-temperature resistance, making them suitable for use in engine compartments. They fully meet the requirements of start-stop systems, offering three times the lifespan and performance of conventional batteries at a higher cost-effectiveness, though they are priced more than twice as much as regular batteries. Currently, Japanese manufacturers primarily promote EFB technology.
