IMPORTANT: Using the ENGINE START feature WITHOUT a battery
installed in the vehicle could cause damage to the vehicle’s electrical
system.
If the engine does turn over, but never starts, there is not a problem with
the starting system; there is a problem somewhere else with the vehicle.
STOP cranking the engine until the other problem has been diagnosed
and corrected.
CALCULATING CHARGE TIME13.
The Chart Method13.1
Use the following table to more accurately determine the time it will take to
bring a battery to full charge. First, identify where your battery ts into the
chart.
Small batteries – motorcycle, garden tractors, etc. – are usually rated in •
Ampere Hours (AH). For example: 6, 12, 32 AH etc.
Batteries in cars and smaller trucks are usually rated in Reserve Capacity •
(RC), Cold-Cranking Amps (CCA), or both.
Marine or deep-cycle batteries are usually rated in Reserve Capacity •
(RC).
NR means that the charger setting is NOT RECOMMENDED.•
Find your batteries rating on the chart below and note the charge time
given for each charger setting. The times given are for batteries with a
50-percent charge prior to recharging. Add more time for severely dis-
charged batteries.
