Kohler — Battery Specific Gravity Check
Testing & diagnosis
From a Kohler service manual covering: KG100, KG125, KG125R, KG150, KG180, KG200, KG80. Check it applies to your exact model before use.
Applies to: Kohler KG100, Kohler KG125, Kohler KG125R, Kohler KG150, Kohler KG180, Kohler KG200, Kohler KG80
Procedure
- Use a battery hydrometer to check specific gravity of electrolyte in each cell (filler-cap batteries only).
- Hold the hydrometer vertically and read the value.
- Correct the reading using the temperature correction table if the hydrometer lacks one.
- Battery is fully charged if corrected specific gravity is 1.260 at 26.7°C (80°F).
- Charge the battery if specific gravity is below 1.215 at 26.7°C (80°F).
- Maintain specific gravity within ±0.01 between cells.
Tools required
