Battery Care (non maintenance-free battery) maintenance
⚠ Batteries present the hazard of explosion; do not smoke or allow any ignition source around the battery area.
⚠ Do not disconnect battery cables while the generator set is cranking or running.
⚠ Battery electrolyte can cause severe eye damage and burns to the skin; wear goggles, rubber gloves and a protective apron.
Tools: terminal puller tool, battery hydrometer
- Keep the battery case clean and dry.
- Make certain battery cable connections are clean and tight; use a terminal puller tool to remove the cables.
- Remove corrosion from terminal connections; wash with an ammonia solution or 1/4 pound (about 100 grams) baking soda in 1 quart (about 1 liter) of water.
- After cleaning, flush the outside of the battery and surrounding areas with clean water.
- Identify the cable as positive (+) or negative (-); always connect the negative (-) cable last.
- Maintain electrolyte level by adding distilled water; fill each cell to the split-level marker.
- Use a battery hydrometer to check specific gravity of each cell; charge if below 1.215.
- Stop charging when electrolyte specific gravity reaches 1.260 at approximately 80 F (27 C).
