AINTENANCE
BattaMax batteries do not require equalizing or electrolyte leveling but periodic inspections and parameter
recording will ensure effective operation and identify issues before they become problematic.
1. Examine the outside appearance of the battery. The tops of the batteries and terminal connections
should be clean and dry, as well as free of dirt and corrosion.
2. Check for any evident fluids. If fluid is present on the top of the battery, it generally indicates that the
battery is being overcharged.
3. Check battery cables and connections. Replace any damaged cables and tighten any loose
connections.
4.
The following will only be done when all electrical connections are completely disconnected from the
battery
. Clean the top of the battery, terminals and connections with a cloth or brush, and a solution of
baking soda and water (1 cup of baking soda to 1 gallon of water). Rinse with water and dry with a clean
cloth and re-apply a thin coat of terminal protector spray. Thoroughly and completely dry the battery
before attaching electrical connections.
5 STORAGE
Batteries may be stored prior to installation for up to 2 years at 25
