Battery Charging and Replacement
Page 8-2 Mastertech 3100 Operator’s Manual
CHARGING THE BATTERY PACK
The Mastertech constantly charges the NiCad battery pack as long as it is connected to a 12 VDC power
source. In normal use, the tester will keep the battery pack adequately charged. However, if the tester is used
for extended periods of time with the vehicle ignition off, or stored for an extended period of time without
use, the NiCad battery pack may become discharged.
To recharge the battery pack, connect the tester to a 12 VDC power source such as the vehicle battery or the
12-volt AC/DC power supply or remove the six batteries from the battery pack and recharge the individual
cells in a commercially available AA cell NiCad battery charger. It takes approximately 16 hours to fully
recharge the battery pack. However, 4 hours of charging time will provide a partial charge and will allow
approximately 30 minutes of tester operation.
Remember, the battery pack is required only when power is not available at the cigarette lighter socket. If the
battery pack is not charged and you need to use the tester, simply connect the tester directly to the vehicle's
battery with the Battery Adapter Cable and cigarette lighter DC power cable supplied with the tester kit.
This will allow operation of all diagnostic procedures with the tester and will start recharging the battery
pack at the same time.
It is recommended that the battery pack be charged overnight using the AC/DC power supply at least once a
week (or more often if required). You can't charge the battery pack too often.
If “ATTENTION! TESTER BATTERY VOLTAGE LOW” is displayed after the battery pack has been
properly charged, then the NiCad batteries are not capable of being recharged and must be replaced.
REPLACING THE NICAD BATTERIES
The capacity of the NiCad batteries will decrease over time and will need to be replaced periodically. The
six batteries originally equipped with the tester are 1.2-volt High Capacity 600 milliampere hour (mAh), AA
size, NiCad rechargeable batteries. This type of battery is available at certain electronic supply stores, or
may be ordered from the nearest Vetronix Service Center listed in the Introduction. When replacing NiCad
batteries, always replace all six cells. This will result in maximum battery life.
CAUTION
CAUTION!
Only use NiCad rechargeable batteries in the Mastertech battery pack.
Other types of batteries may burst causing personal injury and damage to
the tester.
