The lifespan of pane solar batteries can vary depending on several factors, including the type of battery, usage patterns, maintenance, and environmental conditions. Generally, lead-acid batteries used in solar installations can last anywhere from 3 to 10 years, depending on their quality and usage. Lithium-ion batteries, on the other hand, have a longer lifespan and can last between 10 to 15 years or even more. For example, Anker's portable power stations, with their proprietary InfiniPower™ technology and LiFePO4 batteries, are designed to last over a decade, even with daily use.
