6 Frequently Asked Questions about “Battery discharge cycle”

What is a battery cycle?

A charging cycle is completed when a battery goes from completely charged to completely discharged. Therefore, discharging a battery to 50% and then charging it back up to 100% would only be counted as 1/2 of a single battery cycle. Battery cycles are used as an estimate of what a battery's overall lifespan will be.

What is a charge cycle?

A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time.

What constitutes a discharge cycle?

A discharge/charge cycle is commonly understood as the full discharge of a charged battery with subsequent recharge, but this is not always the case. Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery.

What is a rechargeable battery cycle?

Cycle life refers to how many complete charges and discharges a rechargeable battery can undergo before it will no longer hold a charge. A charging cycle is completed when a battery goes from completely charged to completely discharged.

What is battery charging and recharging cycle in a PV system?

The key function of a battery in a PV system is to provide power when other generating sourced are unavailable, and hence batteries in PV systems will experience continual charging and discharging cycles. All battery parameters are affected by battery charging and recharging cycle.

What does deep discharge mean on a battery?

The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge".
