Scientific maintenance greatly extends the service life of household LiFePO4 batteries. Keep the installation environment dry and ventilated, avoiding dampness, direct sunlight and rain, with a suitable working temperature of -20℃ to 60℃. Fully charge the battery once a week to calibrate the BMS and prevent capacity virtuality. For long-term idle storage, maintain the power at 50%-70%, and avoid long-term full or empty power storage. Regularly check circuit interfaces to prevent looseness and aging, avoid overload power use and violent collision to reduce battery loss and maintain stable energy storage performance.
