Maintenance and care Batteries normally produce explosive gases that can cause personal injury. Do not allow flames, sparks, or lit smoking materials to come near the battery. When charging or working near a battery, always cover your face, protect your eyes, and provide ventilation. Batteries contain sulfuric acid that can burn skin, eyes, and clothing. Applying too much pressure on the ends when lifting a battery could cause acid to spill. Lift the battery with a carrier or with your hands on opposite corners. Servicing your battery The low-maintenance battery has removable vent caps for checking the electrolyte level and adding water. Check the electrolyte level every 24 months or 40, 000 km (24, 000 miles) in average temperatures below 32 °C (90 °F). Keep the electrolyte level in each cell up to the level indicator. Do not overfill. 143
