Cycle life is the number of complete charge-and-discharge cycles a battery delivers before its capacity falls to 80 percent of the original rated figure, measured under defined test conditions of depth of discharge, charge rate, and temperature.<\/p>\n\n

Why it matters for home backup power<\/h2>\n\n

A home backup battery cycles every day: charged when the grid is available, discharged during each outage. Those cycles accumulate over years, and cycle life is the number that determines how long the battery performs before capacity drops too far to meet your needs. A higher, honestly stated cycle life lowers the real cost of ownership: a battery rated for 6000+ cycles to the 80 percent end-of-life point costs far less per cycle than one rated for a fraction of that.<\/p>\n\n

Two operating variables shape the real-world cycle count your battery delivers. First, depth of discharge: a battery drawn down more deeply each day degrades faster than one cycled at a shallower range, so the rated figure always states which depth was used in testing. Second, temperature: cold conditions accelerate degradation, and in climates with freezing winters a standard LiFePO4 battery must NOT be charged below 0 C without BMS self-heating. It can discharge down to about minus 20 C with reduced capacity; only charging requires cells to be above 0 C.(Source: Battery University BU-808<\/a>)<\/p>\n\n

Cycle Life in practice<\/h2>\n\n

Key numbers<\/h3>\n\n

LiFePO4 chemistry delivers substantially longer cycle life than lead-acid or other lithium chemistries. Genixgreen LiFePO4 systems are rated for 6000+ cycles to the 80 percent end-of-life point, scaling from about 5 kWh to 16 kWh for homes and into the MWh range for commercial sites. For energy planning, usable output is about 85 percent of nameplate per cycle: depth of discharge of 80 to 95 percent combined with one-way discharge and inverter efficiency of 90 to 95 percent.<\/p>\n\n

Always ask a supplier for the test conditions behind a cycle-life headline: depth of discharge, charge rate, and temperature. A figure quoted without those conditions is a marketing number, not a specification you can plan against.(Source: Battery University BU-808<\/a>)<\/p>\n\n

Cycle life vs calendar life<\/h3>\n\n

Cycle life counts usage events; calendar life counts elapsed time. For a battery cycled daily the two converge closely. A system that sits infrequently used still ages through calendar degradation even if its cycle count stays low, so state-of-health monitoring matters alongside tracking total cycles.<\/p>\n\n

How Genixgreen uses Cycle Life<\/h2>\n\n

Genixgreen has built LiFePO4 storage in its own factory since 2011 and ships to 100+ countries, with local stock in Odesa for delivery across Ukraine. Every home and commercial system in the range is rated for 6000+ cycles to the 80 percent end-of-life threshold. The integrated BMS manages charge rate and depth of discharge in real time, keeping each cycle within the rated operating window and protecting the full cycle-life budget.<\/p>\n\n
