The harvester comes equipped with two maintenance-free 12-volt batteries for John Deere engines. Checking electrolyte level is not necessary.

NOTE: You can cause battery damage when trying to remove caps.

Never check battery charge by placing a metal object across the posts. Use a volt meter or hydrometer. Always remove grounded (-) battery clamp first and reinstall it last.

CAUTION: Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn

skin, eat holes in clothing, and cause blindness if splashed into eyes.

1. Wear eye protection and rubber gloves.
2. Use proper jump-start procedure.

CAUTION: Battery posts, terminals, and related accessories contain lead and lead composites. Wash hands after handling.
