The aluminium battery case contains the 7.4V
Lithium Ion (Li-Ion) battery pack and an internal
charging circuit. Supplied with the GPX-4500 is
a mains charger adaptor and a 12V vehicle
charger adaptor.
When fully charged, the battery will provide
enough power to operate the detector for
approximately 12 hours.
The charger will recharge a flat battery in
approximately 5 hours, but partially discharged
batteries require a shorter recharge time. There is
no need to fully discharge the Li-Ion battery before
recharging, it can be recharged at any time you are
not detecting.
Note: Some after market coils can drain the battery at
a higher rate which may reduce your operating time
by up to 30%.
Mains Charger Adaptor
The mains charger adaptor will charge the battery
from local mains (AC) power outlets.
To Charge with the Mains Charger Adaptor:
1 Disconnect the power cable from the battery.
2 Connect the mains charger adaptor to the
battery power plug and the wall socket.
3 Switch the wall socket on.
Vehicle Charger Adaptor
The vehicle charger adaptor will charge the
battery from the accessories socket (cigarette
lighter) of most motor vehicles. The socket must
be 12–24VDC.
To Charge with the Vehicle Charger Adaptor:
1 Disconnect the power cable from the battery.
2 Connect the vehicle charger adaptor to the
battery and to the vehicle accessories socket.
The colour scheme of the tri-colour LED (pg. 20)
will indicate the status of the charging process.
Note: Don't leave the battery on charge in a closed
vehicle on a hot day as it is temperature protected
and will stop charging.
Charging the Battery
Tip: A spare battery is
available as an accessory. If
travelling into remote areas
a spare battery will ensure
you can continue detecting
for long periods of time.
To prevent damage to the battery, do not
start the vehicle's engine while the battery
is connected.
Make sure your vehicle's battery is in good
condition before using it to charge the
GPX-4500 battery.
The colour scheme of the tri-colour LED (pg. 20) will
indicate the status of the charging process.
Caution: The battery should initially be charged
for 8 hours before use.
