Corrosion on battery terminals and internal metal surfaces

Safety first: Turn OFF the generator and disconnect battery negative first, then positive. Wear eye protection and gloves.

Steps:

• Clean battery terminals: Neutralize corrosion with a baking soda and water solution, then scrub with a wire brush. Rinse and dry.
• Check charger voltage: Ensure the Honeywell charger is not overcharging (should be around 13.2–13.8V). Replace charger if voltage is excessive.
• Protective spray: Apply battery terminal protectant and a light corrosion inhibitor to exposed metal surfaces.
• Improve sealing: Inspect enclosure seals and repair any gaps that allow salt spray or moisture inside.
