You definitely don’t want to get in the middle of nowhere with a dead battery. Whether you’ve had your deep-cycle battery for years or you just bought a brand new one, knowing how long it should last is important.
Many factors influence the life cycle of a battery, but before we get into them, we’re going to cover what exactly a battery life cycle is and how to calculate it. You can also check out here to know more about battery life cycles.
As you use your battery and recharge it, it slowly loses the ability to return to its original capacity. The life cycle of a battery is the number of charges and discharge cycles that it can complete before losing performance.

How Do You Calculate Battery Life Cycle?
In reality, the first time you discharge your battery, it will not recharge to its full capacity. Of course, this doesn’t mean your battery has reached the end of its life.
Each manufacturer provides data on acceptable performance and capacity reduction before determining the life cycle is reached. There is not a standard test, but a general rule of thumb is that the life cycle of the battery is the number of cycles you get before you cannot recharge your battery to more than 80% of the original capacity.
How Is The Depth Of Discharge Determined?
Another way to understand battery capacity is in terms of the depth of discharge. Depth of discharge is the percentage of the battery capacity that has been used relative to the total capacity. For example, a brand new battery with a 100 Ah rating discharged down to 60 Ah would have a 40% depth of discharge for that cycle.
