Using Test Indicator
The Test Indicator measures the specific gravity of the electrolyte. Specific Gravity (SG) of the electrolyte will show state-of-charge (voltage). The test indicator WILL NOT show cranking capacity of the battery. Look into the sight glass and note the color of the indicator. Refer to the following description of colors:

NOTE: GREEN = 75 to 100% state-of-charge

The battery is adequately charged for further testing and may be returned to use. If the vehicle will not crank for a maximum 15 Seconds.

NOTE: BLACK OR DARK = 0 to 75% state-of-charge The battery is INADEQUATELY charged and must be charged until green dot is visible, (12.4 Volts or greater) before the battery is tested or returned to use.

NOTE: CLEAR COLOR = Replace Battery

WARNING: DO NOT CHARGE, ASSIST BOOST, LOAD TEST, OR ADD WATER TO THE BATTERY WHEN CLEAR COLOR DOT IS VISIBLE. PERSONAL INJURY MAY OCCUR.

A clear color dot shows electrolyte level in battery is below the test indicator. Water cannot be added to a maintenance free battery The battery must be replaced. A low electrolyte level may be caused by an over charging condition.

Causes Of Battery Discharing
It is normal to have a small 5 to 25 Milliamperes continuous electrical draw from the battery. This draw will take place with the ignition in the OFF position, and the courtesy, dome, storage compartments, and engine compartment lights OFF. The continuous draw is due to various electronic features or accessories that require electrical current with the ignition OFF to function properly. When a vehicle is not used over an extended period of Approx 20 Days the IOD fuse should be pulled. The fuse is located in the power distribution center. Disconnection of this fuse will reduce the level of battery discharge.

Abnormal Battery Discharging
- Corroded battery posts, cables or terminals.
- Loose or worn generator drive belt.
- Electrical loads that exceed the output of the charging system due to equipment or accessories installed after delivery
- Slow driving speeds in heavy traffic conditions or prolonged idling with high-Amperage electrical systems in use.
- Defective electrical circuit or component causing excess Ignition Off Draw (IOD).
- Defective charging system.
- Defective battery
