Determine the charge level of your battery with a hydrometer or electronic percent of charge tester. Determine the ampere hour rating of
your battery. It may be on the battery information label. If the battery is rated in Reserve Capacity, convert to ampere hour rating using
the following formula:
Ampere Hour rating =
(Reserve Capacity) + 16 Example: AH rating = (168 Reserve Capacity) + 16 or AH = 100
(2) (2)
Reserve Capacity is in minutes.
Use the following formula to determine the time of charge required:
(AH x % of charge needed) divided by amp setting of the charger, times 1.25 = hours of charge:
Example: State of charge of the battery is 50%
Percent of charge needed is 100% - 50% = 50% (.50 decimal)
Ampere rating of the battery is 100AH
Charger setting is 10 amps
100 x .50 = x 1.25 = 6.25 hours of charge needed
10
+ 1.00 hour more if charging a deep cycle battery
7.25 hours total for a deep cycle battery.
A hydrometer reading of the specific gravity of the electrolyte (fluid) of the battery in good condition should be between 1.25 and 1.28.
When a battery reaches 80-85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling
will become more vigorous.

1. With the charger unplugged from the AC outlet, connect
the charger to the battery following instructions given in
section F.
2. Plug the charger AC power cord into the AC outlet, then set
selector switch to the 12 volt Engine Start position.
3. Crank the engine by turning the ignition key of the vehicle.
Follow the duty cycle printed on the front panel of your
charger for proper ON / OFF times. During extremely cold
weather or when the battery is severely exhausted, charge
the battery for about 5 minutes before cranking the engine.
4. If the engine fails to start, charge the battery for 5 more
minutes before attempting to crank the engine again.
1. Before charging any battery, make sure the electrolyte
(battery liquid) in each cell is at correct level.
2. Set switch to the OFF position.
3. If the battery is being charged inside the vehicle, use
connection procedures outlined in Section F. Should the
battery be removed from the vehicle, follow the instruction
in Section G. Now plug the charger into the AC outlet.
4. Set the charge rate switch to the desired charge position.
See charge rate chart.
NOTE: These battery chargers are MANUAL type chargers
and MUST have the charging monitored regularly.
The battery can overcharge if the charging is not
stopped when the battery is charged.
5. After the engine starts, move the charge rate switch to the
off position and then unplug the AC power cord from the
outlet before disconnecting the output clips from the battery.
Do not try to engine start a vehicle without a battery in it.
You may damage the vehicle’s system. If the engine spins,
but doesn’t start after several starting attempts, there is a
problem with the engine of the vehicle other than its starting
system. STOP cranking the engine until the other problem
has been found and corrected.
