BAD (RED LED LIGHT):
Battery may be defective (e.g. a bad cell).
5.
Digital LED code display "c.b":
a) If the battery volts is under 12.3V, "c.b" (Charge battery) will be shown on LED display.
Please fully charge the battery before test. After charging, please wait 15-30 minutes to
let the voltage stable & make load test. If reading is still below 12.3V with "c.b", the
battery should be replaced immediately.

b)
If the battery volts is above 13.2V, "c.b" (Charge battery) will be shown on LED display. While
in making load test connected with battery from vehicle, please turn off the engine & turn on
the head light in a second to wait the battery voltage under 13.2V, and then turn off the head
light to test the battery.
c)
In a battery that has just finished its charging cycle, the voltage is unstable. Therefore it is
recommended to wait for 15-30 minutes, until the voltage is
below 13,2 V, before performing a load test.”

If the tester indicates poor battery condition, allow the battery to stabilize for a few minutes
and check the open circuit voltage by voltmeter. This is a good measure of the percent charge
in the battery. The battery is considered charged if it measures 75% or more. If it failed the load
test with 75% charge, it should be replaced. If the battery charge measures less than 75%, it
