Regular cleaning and maintenance are essential to extend the service life of home energy storage batteries. Wipe dust on the device surface with a dry soft cloth; never flush or spray water directly on the equipment to avoid short circuit caused by water penetration. Regularly check and fasten loose or oxidized wiring terminals and interfaces to ensure good contact. Observe indicator lights and display screens to confirm normal operation of charging, heat control and protection systems. For long-term idle storage, maintain 50%-60% battery power and recharge monthly to prevent battery damage from power loss and ensure standby availability.
