- The battery has a built-in hydrometer (1). The hydrometer
lens provides a visual indication of the condition of the electrolyte.
- Tap lightly on the lens and observe the built-in hydrometer
(1).
- Under normal operation, one of three color conditions on the hydrometer
(1) is possible:
| • | Green ball visible (2). |
| • | This condition indicates a sufficient state of electrolyte (5) charge
(65 percent or above) for normal charging system operation. |
| • | Dark lens (3) (Green ball not visible) |
| • | This condition indicates an insufficient state of electrolyte (5) charge
below 65 percent). Recharge the battery before further testing. |
| • | Clear lens (4) (or Yellow lens). |
| • | This condition indicates that the electrolyte (5) is low. The battery
electrolyte (5) cannot be refilled. Replace the battery. |
- A low electrolyte (5) level can be caused by any of the following
conditions:
| • | Excessive battery tipping |
- When finding a battery in this condition it may indicate high
charging voltages caused by a faulty charging system. The charging and electrical
systems should be checked.
- If there is a cranking complaint, inspect for trouble in the
charging or electrical systems.
- If a cranking complaint exists and is caused by the battery, the
battery should be replaced.
