Battery cycle life is the number of full charge and discharge cycles a home battery is rated or warranted to deliver while still meeting a stated capacity floor (often called state of health). Warranties usually count full equivalent cycles: total energy moved divided by usable capacity, so several shallow discharges can add up to one full cycle.
A published cycle count is a warranty or datasheet figure, not a promise of how many cycles a typical home will run. Do not read a bare cycle number as "typical yearly use" without the context of tariff, pack size and depth of discharge. Brands also quote different units (years, cycles, or total throughput), so compare the document for your purchase date rather than a marketing headline alone.
What it means for a home battery
For Habo readers the useful questions live in the long guide: how throughput on a time-of-use tariff compares with the warranty cap, how state of health floors work, what happened when a warranty writer entered administration, and why the inverter warranty can matter as much as the cell cycle count. Read home battery cycle life and warranty UK 2026 for those worked figures instead of repeating them here. Habo's offer is an electrician-wired EcoFlow STREAM from £2,499. Join the waitlist.

Frequently asked questions
Battery warranties usually count full equivalent cycles as total energy throughput divided by usable capacity. Two half-discharges count as one full cycle.
Not necessarily. Real yearly throughput depends on tariff, sizing and how often you force-charge. See Habo's cycle-life and warranty guide for worked UK patterns rather than treating a bare cycle count as typical.
Yes. Many packs have a separate inverter or electronics warranty from the cell warranty. The cycle-life guide explains why that split matters.
