What is Cycle life?
In short
How many charge and discharge cycles a battery is rated for before its capacity falls to a set level.
Cycle life is the number of full charges and discharges a battery is rated to complete before its capacity drops to a stated level. It tells you the working life of a home battery rather than its size, so two units with the same capacity can age very differently. The ALLDREI balcony set with storage is rated at 10,000 cycles, DATOUBOSS at 8,000 cycles, and Deye at 6,000 cycles. Ask which capacity level the figure assumes, since makers test to different thresholds.
