Visual inspection

Before measurements such as open−circuit voltage, gravity of electrolyte or the battery load test are carried
out, a visual inspection of the battery must be performed.
Through this check, it can be determined:
• Whether the housing of the battery is damaged. Acid can leak out due to damage of the housing.
• Whether the battery terminal (battery line connections) is damaged. Contact of the line connections
cannot be guaranteed if the battery terminal is damaged. This can cause a line fire and malfunctions in
the electrical system.

Check acid level

CAUTION
The accident prevention regulations must be observed when handling battery acids.
Wear suitable protective clothing and protective glasses.
Only illuminate the inside of the battery with a torch.
Never illuminate the inside of the battery with a naked flame.
Do not handle a naked flame or lit cigarettes near batteries.
Observe the disposal regulations for batteries when disposing of batteries and sulphuric acids.
Note
• Use a commercially available battery filling bottle.
• The correct acid level of the battery is an important factor for long and efficient operation of the
battery.
• When the acid level is too low, a capacity loss (performance loss) of the battery occurs which is
caused by the cell plates drying out. If the cell plates are not surrounded by electrolyte (battery acid),
it will lead to corrosion of the lead plates, the plate bridges and the cell connectors. The result of the
corrosion is that battery functioning cannot be guaranteed. The battery will become useless.
• If the acid level is too high, damage can occur by the battery acid leaking out (sulphuric acid water
mixture) outside the battery.
1. Switch ignition off and remove ignition key.
