4.60.15 Checking the acid level
- Clean battery surface. Open locking cap.
- The fluid should typically be 10 to 15 mm
above the plates or at the level of the
control device. Observe the instructions
from the battery manufacturer!
- Refill with distilled water (not acid!), if
necessary.
- Mount locking caps.
4.60.16 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 shows at
least 12.5 volts, then the battery is ok. The
battery must be charged immediately once
below 12.5 volts.
4.60.17 Checking the acid density
Using a hydrometer (Fig. 4/Fig. 5) measures
the acid density of each individual cell. The acid
temperature must be at least at 10°C during
this process.
The acid densities of the individual cells may
not deviate by more than 0.03kg/l. Otherwise,
the battery is defective and must be replaced.
It should further be noted that the acid density
is lower under tropical conditions. See tables,
Tab. 1.
