How long will a 12V 100Ah LiFePO4 battery last?

The AJPOWER 12V 100Ah LiFePO4 battery, recognised for its deep cycle characteristics, outlasts typical lead-acid batteries. With an average lifespan of 3000-5000 cycles, this battery can deliver consistent power for a long time.

The depth of discharge (DoD), charging and discharging rates, operating temperature, and general maintenance all have an impact on the life expectancy of a LiFePO4 battery. Deeper discharge cycles and faster charging and discharging rates might lower battery longevity marginally.

We may estimate the battery's estimated duration by assuming an average DoD of 50%, which is usual for deep cycle applications, and considering the battery's capacity of 100Ah.

If you used 50Ah of electricity per day, the battery would last around two days before needing to be recharged. It is crucial to note, however, that continuously draining the battery until it is completely exhausted might diminish its total lifespan. As a result, it is suggested to keep a moderate DoD to maximise battery longevity.

It's also worth noting that LiFePO4 batteries provide constant performance throughout their lives. They do not suffer from the same voltage sag or capacity loss as lead-acid batteries.

Finally, the battery's actual lifespan will be determined by unique usage patterns, charging practises, and environmental circumstances. Regular maintenance and suitable charging practises can help extend the life of the battery and assure peak performance.
