5-Year Lifespan & Up to 6000 Cycles 12V 100Ah LiFePO4 Batteries Can be Cycled 3000~6000 with 5+ Years Life Span. live more than 3000 cycles at 100%, and 5000 cycles at 80% depth of discharge, 8000 cycles at 50% depth of discharge without decreasing in performance. This means that the cycle life of LiFePO4 batteries is at least 3-5 times that of lead-acid batteries! It is safer, more stable, and environmentally friendly than lead-acid batteries, and reduces overall usage costs.
