Checking Condition and Cleaning

trolyte 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).
When solution stops bubbling, rinse off the battery
with clean water.
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, loose connections, and corrosion. Tight-
en 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 might indicate bat-
tery has been frozen, overheated, or overcharged.
6. Inspect battery case for cracks or leaks.
7. Check battery fluid level of unsealed batteries. See
Checking Fluid Level.
