Battery Voltage Test (No Load
Applied)
NOTE: A voltage test is carried out on a battery
without discharging current. It is the simplest
and most commonly used. However, be aware
that the voltage test can be good; while the
battery does not have enough power to crank
the engine .A load test gives a more accurate
condition of the battery.
A voltage reading provides an instant indication
of the state of charge of the battery, not of it's
current output capacity. A load test gives a more
accurate indication of the battery's condition.
If the battery has just received a charge,
allow it to rest for 1-2 hours before taking
a voltage reading.
FULLY CHARGED BATTERY VOLTAGE:
12.6 Vdc minimum.
NOTE: A battery that shows a voltage of 12.0
Vdc is considered completely discharged and
need to be recharged.

Battery Load Test

This is the best test to indicate a battery
condition. Use a load testing device and has a
500 Amp adjustable load.
Apply a load of 3 times the ampere-hour rating
of the battery. At 14 seconds into the test, check
battery voltage.
14 seconds = Min. 10.5 Vdc @ 20 ℃

Battery Removal

1. Disconnect BLACK (-) cable first, then the
RED (+) cable.
NOTICE: Always respect this order for removal;
disconnect BLACK (-) cable first.
2. Remove battery strap retaining nut.
3. Unhook the top of battery strap.
