Service & Maintenance
Batteries should be carefully inspected on a regular
basis in order to detect and correct potential problems
before they can do harm. This routine should be started
when the batteries are first received.
Inspection
• Look for cracks in the case
• Check the battery, terminals and connections to
make sure they are clean, free of dirt, fluids and
corrosion
• All battery cables and their connections should
be tight, intact, and NOT broken or frayed
• Replace any damaged batteries
• Replace any damaged cables
• Check torque on terminal bolts
