Technical explanation
Two 50 % discharges may count as one equivalent cycle when using the same reference capacity. Temperature, power, discharge depth and high charge states affect aging. Check test conditions.

TL;DR
An equivalent full cycle accumulates discharges amounting to a reference capacity. Cycle count alone does not predict battery service years.
Definition
Cyclic aging results from repeated battery use. Calendar aging also occurs over time, even without cycles.

Swiss context
Read warranty limits in years, cycles or energy throughput, residual capacity and exclusions. Dividing advertised cycles by annual use does not guarantee operating life.

FAQs — Battery cycle
How many cycles will my battery do each year?+
Annual count depends on hourly flows, size and settings. Request a simulation of equivalent cycles or energy throughput rather than a national average.
Does the 10 year warranty cover 6 000 cycles?+
The answer depends on the contract, not cycle arithmetic alone. Keep operating records and check residual capacity, compliant installation and claim conditions.
