Depth of discharge means how much of a battery’s actual power can be used out of its total power capacity.
Battery capacity is the maximum energy a battery holds when fully charged. However, you can't use all of it without damaging the battery. DoD indicates the safe portion of energy you can utilize without compromising the battery's lifespan.
If your battery has an 80% DoD, it means you can only use 80% of its total capacity.
- Why a Higher DoD is Beneficial?
A higher DoD allows you to use your battery for longer periods before needing a recharge.
- How Does Battery Discharge Affect Cycle Life?
But greater DoD and frequent discharging reduce the number of charge-discharge cycles a battery
can endure. This is why it’s generally not recommended to discharge a battery entirely. The
recommended battery DoD varies by the type of battery and manufacturer.
- Is it Okay to Fully Discharge a Battery?
You should avoid doing so as much as possible. And when that happens, you can cause permanent
damage to the battery.
- What Happens If You Discharge More Than Your Battery’s Rated
Exceeding the rated DoD accelerates the deterioration of battery plates, affecting its ability to
charge and discharge reliably.
