How Long Will a 12V 100Ah Lithium Battery Last?

by

A 12V 100Ah lithium battery typically lasts 8-10 years under normal use or 5-7 years in high-demand applications. Its runtime per charge depends on energy consumption: for example, powering a 500W device at 50% depth of discharge (DoD) provides ~1.2 hours. Factors like temperature, discharge rates, and maintenance significantly impact longevity. Deespaek 12V LiFePO4 Battery … Read more

How Long Will a 36V 100Ah Battery Last?

by

A 36V 100Ah battery typically lasts between 5–20 hours, depending on the device’s power draw. For example, a 500W motor would drain it in 7.2 hours (3600Wh ÷ 500W). Factors like temperature, discharge rate, and battery chemistry (e.g., lithium vs. lead-acid) significantly impact actual runtime. Always check your device’s wattage for precise estimates.
