Corrosion visible on battery terminals and metal parts inside SDMO generator enclosure; strong smell of battery acid.

Safety first: Wear eye and hand protection. Neutralize acid spills with baking soda solution and avoid sparks near the battery.

• Clean terminals: Disconnect battery and clean corrosion from terminals and cable lugs. Apply protective grease after reassembly.
• Check charger output: Measure charger voltage and adjust or replace if it exceeds recommended float voltage.
• Improve ventilation: Ensure the battery compartment has adequate ventilation to disperse hydrogen gas.
• Replace aged battery: If the battery is old and gassing heavily, replace it with an SDMO-recommended type.
