ACHTUNG!
Attention!
The following instructions do not apply to maintenance-free starter batteries.
Strictly observe the manufacturer instructions!
4.18.14 Checking the acid level
• Clean battery surface, open locking caps.
• The fluid should typically be 10 to 15 mm above the plates or at the level of the
control device. Observe the manufacturer instructions.
• Refill with distilled water (not acid!), if necessary.
• Mount locking caps.
4.18.15 Checking the open-circuit voltage
In order to achieve a correct result, the battery may have been neither connected
to a load nor charged at least two hours before the measurement.
If the open-circuit voltage is to be measured with a built-in battery, first disconnect
the negative terminal and then the positive terminal from the battery. Otherwise,
there is a danger of short circuiting!
• Measure the voltage between the terminals.
If the measuring device displays at least 12.5 volts, then the battery is in order. The
battery must be charged immediately once below 12.5 volts.
