BATTERY TESTING
General
Three different procedures may be performed to provide a
good indicator of battery condition: a voltage test, a conduc-
tance test, or a load test.
A battery may be tested, whether fully charged or not, via
conductance test. In order to perform a load test, however,
the battery must be fully charged.
Voltmeter Test
Refer to Table 7-13. The voltmeter test provides a general
indicator of battery condition. Check the voltage of the battery
to verify that it is in a 100% fully charged condition. If the
open circuit (disconnected) voltage reading is below 12.6V,
charge the battery and then recheck the voltage after the
battery has set for one to two hours. If the voltage reading is
12.8V or above, perform the load test.
CONDUCTANCE TEST
Test the battery using the MCR-101 HD ADVANCED BAT-
TERY CONDUCTANCE AND ELECTRICAL SYSTEM ANA-
LYZER. Perform a battery test as follows:
1. Connect the MCR-101 HD analyzer leads to the vehicle’s
battery.
2. Follow the instructions in the analyzer’s instruction man-
ual to perform a battery test.
The test results will include a decision on the battery’s condi-
tion, the measured state of charge and the measured CCA.
See Figure 7-46. The analyzer’s printer will provide you with a
printout including one of five possible test results:
● GOOD BATTERY–return the battery to service.
● GOOD-RECHARGE–fully charge the battery and return
to service.
● CHARGE & RETEST–Fully charge the battery and
retest.
● REPLACE BATTERY–replace the battery and retest.
● BAD CELL-REPLACE–replace the battery and retest.
NOTE
A REPLACE BATTERY test result may also mean a poor con-
nection between the battery cables and the vehicle. After dis-
connecting the battery cables from the battery, retest the
battery using the out-of-vehicle test before replacing.
