The standard cycle life of 12V20Ah maintenance-free lead-acid batteries is 300-500 charge-discharge cycles, with a service life of 2-3 years for daily household use. Battery capacity attenuates slowly over time, remaining above 85% of the initial value after one year of normal use. Frequent fast charging, deep discharge and use in extreme temperatures will accelerate battery aging. High temperature speeds up plate corrosion, while low temperature temporarily reduces discharge capacity (recoverable after warming up). Replace the battery in time when its capacity drops below 60% or it has obvious endurance reduction.
