Inverter Battery Lifespan & Replacement Year Estimator
Estimate how many years your inverter battery will last before needing replacement. Accounts for battery chemistry (Flat Plate, Tall Tubular, Gel, Lithium LiFePO4), ambient room temperature, and average daily power cut frequency.
Approx. 3.1 years of remaining useful service.
Never fill tap water or RO water in lead-acid batteries. Only use 100% distilled demineralized water to prevent electrode plate sulfation.
