What maintenance is required for the EverStart Maxx 1200A?

The battery is sealed and maintenance-free. When the unit is not in use, charge it at least every 30 days to maintain optimal performance. Periodically wipe the outside with a soft cloth, but do not immerse in water. Inspect adapters, connectors, and wires for wear or damage and contact the manufacturer to replace any worn components.
