BATTERY REPLACEMENT (CONT)

To Check and Add Electrolyte:
1.
Clean off battery caps before removing. Do not allow dirt to get into battery cells.
2.
Clean vent holes in caps to allow gas to escape from cells.
3.
Electrolyte level must not drop below the top of battery plates. Add distilled water to correct level
indicator mark; do not overfill. Add only distilled water from a nonmetallic container. Clean rainwater
may be used in an emergency.
4.
Run vehicle to charge batteries, which will mix added water with the electrolyte. This is very important
in cold weather to prevent battery from freezing and cracking.
To Remove and Retard Corrosion:
Corrosion is the greenish “fuzz” that builds up on the battery posts, terminals, and cables. This corrosion not
only can prevent statting, but will also eat up the cables and connectors.
C A U T I O N
• Make sure battery caps are tight and no cracks are visible in battery case,
so that no alkaline solution (acid neutralizer) reaches electrolyte.
• If the cables overheat, there may be corrosion or a break within the wiring
causing electrical resistance.
If possible, remove corrosion or notify unit
maintenance for replacement.

8.
Remove corrosion with an alkaline solution of bicarbonate of soda and water.
Remove terminal clamps from battery posts and clean with terminal brush.
Clean bolts and nuts. Check for corrosive effects.
Clean battery posts with wire brush and a water/soda solution. Dry battery posts.
Clean any corrosion from tiedowns.
Rinse batteries, connections, cables, and tiedowns with clear water to remove alkaline solution; dry.
Install and tighten terminal clamps. Apply coat of GAA to terminals, bolts, and posts to retard corrosion,
Keep tops of batteries clean and dry to prevent current leakage between terminals.
