D10 - BATTERY ELECTROLYTE DENSITY
CHECK
The electrolyte density varies depending on the temperature concerned, but a minimum of
1260 at 16°C must be maintained. In the shaded area (fig. D10), the battery is in a normal
charge condition. Readings above this zone indicate that the battery needs to be
recharged.
The density should not vary more than 0.025 units between cells.
- Check the electrolyte density in each battery cell using a hydrometer.
- Do not carry out this check immediately after topping up with distilled water. Recharge
the battery for at least an hour before checking the battery electrolyte density.
Handling and servicing a battery can be dangerous, take the following precautions:
- Wear protective goggles.
- Keep the battery horizontal.
- Never smoke or work near a naked flame.
- Work in a well-ventilated area.
- In the event of electrolyte being spilled onto the skin or splashed in the eyes, rinse
thoroughly with cold water for 15 minutes and call a doctor.
