5 XF 95 series Inspection of batteries BATTERIES 4.3 INSPECTION USING A BATTERY TESTER - The general condition of the battery can be checked quickly using a battery tester. For this check, a load is applied to the battery and then the discharge voltage at the battery poles is measured. The load applied to the battery must be at least 3 times the capacity of the battery. - The rule of thumb is that the test can be carried out when the battery is sufficiently charged (relative density 1.25 - 1.28 kg/dm ). At normal temperatures (10-20 C), the charging voltage for a properly charged battery must be 10 volts after 10 seconds.
In the case of a partially discharged battery (relative density 1.25 kg/dm 3 ), the reading should be at least 9 volts. It is important that the voltage be measured directly at the battery poles. 4 200303 4-3
