Battery Warning Label
Voltmeter Test
The voltmeter test provides a general indicator of battery condition. Check the voltage of the
battery to verify that it is in a 100 percent fully charged condition. If the open circuit (disconnected)
voltage reading is below 12.6 V, charge the battery and then re check the voltage after the battery
has set for one to two hours. Refer to Voltmeter Test.

Cleaning and Inspection
Battery top must be clean and dry. Dirt and electrolyte on top of the battery can cause battery to
self discharge.
1. Clean battery top.
2. Clean cable connectors and battery terminals using a wire brush or fine grit sandpaper to
remove any oxidation.
3. Inspect and clean the battery screws, clamps and cables. Check for breakage, loose
connections and corrosion.
4. Check the battery posts for melting or damage caused by overtightening.
5. Inspect the battery for discoloration, a raised top or a warped or distorted case. This might
indicate that the battery has been frozen, overheated or overcharged.
