3. Built-in battery
3.1. Maintenance and care
The built-in battery (hereinafter—the battery) requires careful handling. Observe the
main rules to extend the battery service life.
Do not allow deep discharge of the battery.
Even with the Tester switched off, the battery continues discharging owing to self-
discharge process and to the current consumed by the switching on / off circuit
(approximately 10 μA). At high temperatures, the self-discharge process accelerates. If
the battery voltage drops down to 4.5 volts and below, the battery capacity irreversibly
decreases, after which the battery cannot be fully charged.
Before long-term storage of the Tester (more than 1 month), the battery
should be fully charged and then disconnected.
To disconnect the battery, remove the Tester rear cover by unscrewing 4 fixing screws,
lift the lower unsecured edge of the main printed-circuit board (PCB) (Fig. 1) and shift it
so that the PCB connectors disconnect from the counterparts on the filter board. Throw
the main PCB sideward and disconnect the power wires from the PCB connector
(Fig.2). Replace the PCB and close the Tester rear cover. Upon completion of storage
and prior to using the Tester, re-connect the battery and recharge it.
Do not allow storage of the Tester with a discharged battery at low negative
temperatures.
As the battery discharges, the electrolyte concentration decreases, owing to which
electrolyte may freeze. Electrolyte freezing may cause irreversible mechanical damages
of the battery elements. Besides, at low temperatures, the battery capacity drops down.
Thus, at a temperature of -20°С, the battery capacity is 40% of the rated value.
Charge the battery on a regular basis.
The Tester starts giving audible signals every 10 seconds, if the battery voltage drops
down to 5.4 V during operation. These signals mean that the battery requires charging.
