Daewoo — Battery servicing
Maintenance
From a Daewoo operator's manual — check it applies to your exact model before use.
Before you start
- The battery electrolyte is dilute sulfuric acid; be careful not to stain your body and clothes with it. If stained rinse the stained portion with clean water.
Procedure
- Periodically measure the electrolyte gravity of the batteries.
- Measure the electrolyte temperature and convert using S20 = St + 0.0007(t - 20) when not at the specified temperature.
- Check the battery terminal connections every 600 operation hours for loosened connections and terminal corrosion.
- When the batteries are fouled clean with clean water or tepid water and wipe with dry cloths.
- Apply a coat of vaseline or a grease lightly.
Tools required
- Hydrometer Amazon
