How Does Depth of Discharge Impact Battery Longevity?

Depth of discharge significantly impacts battery longevity. The depth of discharge (DoD) refers to the percentage of a battery’s capacity that has been used. A higher DoD means more energy is drawn from the battery before it is recharged.

Batteries have a limited number of charge and discharge cycles. A deeper discharge reduces the total number of cycles the battery can endure. For example, if a battery regularly discharges to 80%, it may have a shorter lifespan compared to one that discharges to 20%. This is because deeper discharges put more stress on the battery’s materials.

In general, maintaining a lower depth of discharge helps prolong battery life. For lithium iron phosphate (LiFePO4) batteries, like the 12V 100Ah type, keeping the DoD around 20-30% can significantly extend cycle life. The cycles reduce more slowly at these levels.
