In order to prolong battery life, perform regular maintenance and inspections.
Monthly Maintenance
Keep the batteries and battery room clean. •
Measure and record the ambient temperature of the battery room. •
Check for damage and overheating evidence on the terminal, container, and lid. •
Measure and record the total voltage and floating current of the battery system. •
