8. Starter batteries
DANGER
Risk of explosion or fire (oxygen and hydrogen present). The battery must never be
exposed to any naked flames or sparks.
Risk of sparks forming and an explosion . When fitting the battery, never invert the
polarities.
Do not short the battery terminals with a tool or other metal object.
Risk of injury . Battery electrolyte is extremely corrosive. Always protect your eyes, skin
and clothing when handling batteries. Always wear protective goggles and gloves.
In the event of contact with the skin, wash thoroughly with water and soap. If the eyes are
splashed, rinse thoroughly with water and consult a doctor immediately.
8.1. Checking the electrolyte level
The electrolyte level must be approximately 10 mm above the battery plates.
1. Top up with distilled water if necessary.
2. Pour the distilled water carefully to avoid any splashes.
Wear protective goggles and rubber gloves when handling the battery (adding water,
charging, etc.).
Note: some batteries requiring no maintenance form the subject of specific instructions
which must be respected.
After the battery has been topped up, it must be recharged for at least 30 minutes.
8.2. Checking the voltage/acid density
Every 2 months, the following checks must be performed:
1. Check the density of the acid contained in the cells (all the battery cells must have the same density; if this is not the case, the
battery must be replaced)
2. Check the voltage when idle.
Acid density Charge status Voltage when idle Observation / action
1.27 100% Above 12.60 V
1.25 80% 12.54 V
1.20 60% 12.36 V From 60% recharge
1.19 40% 12.18 V Risk of sulphation
1.13 20% Below 11.88 V Unusable
The results of the density and voltage measurements make it possible to define the charge status of the battery. If the charge status is
less than 60%, the battery must be recharged.
