On average, a well - maintained lead - acid battery in a solar battery cabinet can last between 3 to 5 years. Factors such as depth of discharge (DOD), temperature, and charging regime significantly affect their lifespan. They're more affordable upfront but require regular maintenance and don't hold up as well over time. When people talk about battery lifespan, they're often. . Lithium batteries offer superior performance compared to lead-acid batteries, which significantly influences installers' choices. One of the primary advantages of lithium technology is its higher energy density. It will then decline until the sun sets.
