Battery Maintenance Guidelines The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions for transportation, installation, storage or maintenance take precedence over these instructions. • • • • • • • • To prevent damage, inspect batteries every 3 months for: Signs of battery cracking, leaking or swelling. The battery should be replaced immediately by authorized personnel using a battery of the identical type and rating. Signs of battery cable damage.
Battery Safety Notes WARNING! Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery installation, maintenance, service and replacement must be performed only by authorized personnel. Chemical Hazards Any gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric acid, which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and corrosive.
