Inspecting Battery Condition and Cleaning
Proceed as follows to inspect and clean battery:
1. See Figure 3-3. Verify top of battery is clean and
dry. Dirt and electrolyte on top of the battery can
cause battery to self-discharge. Clean battery top
with a solution of baking soda (sodium bicarbonate)
and water (5 teaspoons baking soda per quart or
Liter of water). Rinse off battery with clean water
when solution stops bubbling
2. Clean cable clamps and battery terminals using a
wire brush or sandpaper to remove any oxidation.
3. Inspect battery screws, clamps, and cables for
breakage, and for loose connections and corrosion.
Tighten and clean as necessary.
4. Inspect battery posts for melting or damage caused
by over tightening.
5. Inspect battery for discoloration, raised top, or a
warped or distorted case, which may indicate bat-
tery has been frozen, overheated, or overcharged.
6. Inspect battery case for cracks or leaks.
7. Verify battery state of charge. See
of Charge.
8. Replace battery if necessary. See
Battery.
Verifying State of Charge
