TESTER 51
6.0 BATTERY CHARGING AND
REPLACEMENT
The Tester 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/DC 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 one
hour.
Always turn the Tester off when not in use!
To confirm that the battery pack is sufficiently charged for testing:
1. Turn the Tester on (press o) before connecting the Tester to an external power
source such as the vehicle battery or AC/DC 12-volt adapter.
2. If the Power-up screen is displayed for one minute, the battery pack probably has
enough charge to test a vehicle.
3. If the screen on the left is displayed within one minute of powering up the Tester with
the battery pack or if this screen appears during testing, the NiCad battery pack
requires charging.
