11. Battery charging
The metal detector BLISSTOOL LTC42 has 12V/2.5Ah NiMH battery that is placed inside the
power supply module. The battery has around 500 charging/discharging cycles (battery “life”),
after which its capacitance drops sharply and must be replaced with a new battery.
The battery charging has to be done only by the automatic battery charger BLISSTOOL
DA12250 (~220/12V, 250mA) that is included in the standard kit.
The specified battery charger is designed to ensure the quality and safety during the battery
charging process.
To charge the battery, plug in the battery charger jack into the connector that lies on the front
panel of the power supply module. Then the battery charger contact-plug is plugged into the
~220V circuit.
The charging continues from 3 to 12 hours, depending on the battery level of discharge.
It is not required to keep a close watch on the charging process, as the charger is automatic
and after the battery charging is finished it switches to a stand-by mode, which protects the
battery from over-charging.
The green light indicator lits up when the battery charger is plugged in ~220V circuit, which
indicates that the charger is working properly.
The charging process and the charging stages are indicated with the different light intensity of
the red light indicator – when the battery is discharged, it is either out or is dimly lit up, while
during the charging process the intensity is increased, resulting in a bright intensity when fully
charged.
After the charging process has been finished, the battery charger should be switched off
following the reversed order: plugging off the ~220V circuit by pulling out the power supply
contact-plug from the wall-plug, then the battery charger jack is plugged off.
During charging, the metal detector should be switched off. Switching on the detector while
being charged could cause serious damage to the electronic control module or to decrease the
detector’s search quality.
The built-in battery does not need any further maintenance besides being charged.
