8. BATTERY CHARGING AND
REPLACEMENT
The Mastertech contains two types of batteries: a set of rechargeable Nickel-Cadmium (NiCad) batteries and
a replaceable Lithium battery.
NICAD BATTERY PACK
The NiCad batteries are housed in a removable battery pack located on the bottom underside of the tester.
For normal use, the tester should be powered from the vehicle's cigarette lighter or battery adapter cable, or
by the AC 12-volt adapter. However, on some vehicles power is not available at the cigarette lighter when
the ignition is off or when the engine is cranking. The NiCad battery pack provides power to the tester under
these conditions. When fully charged, the battery pack can power the tester for up to two hours.
To confirm that the battery pack is sufficiently charged for testing:
1. Turn the Mastertech on (press O) before connecting the tester to an external power source such as the
vehicle battery or AC 12-volt adapter.
2. If the screen below is displayed when powering the tester with the battery pack, the NiCad battery pack
requires charging.
CAUTION
CAUTION!
Always turn the Mastertech off when not in use!
