I. | ENGINE START |
|
|
1.Set charge rate switch and timer to OFF positions.
2.With the charger unplugged from the AC outlet, connect the charger to the battery following instructions given in section F.
3.Plug the charger AC power cord into the AC outlet, then move timer from OFF to HOLD position.
4.Set the charge rate switch to the engine start position that matches the vehicle battery and then crank the engine. Fol- low 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.
5.If the engine fails to start, charge the battery for 5 more min- utes before attempting to crank the engine again.
6.After the engine starts, move the charge rate switch to OFF and unplug the AC power cord from the outlet before discon- necting DC clips.
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 crank- ing the engine until the other problem has been found and cor- rected.
J. | CHARGE PERIOD |
|
|
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
7.25hours 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
K. | BATTERY CHARGING |

|
CHARGER MUST BE ASSEMBLED BEFORE USING.
1.Before charging any battery, make sure the electrolyte (bat- tery liquid) in each cell is at correct level.
2.Set all switches and timers to the OFF position.
3.If the battery is being charged inside the vehicle, use con- nection procedures outlined in Section F. Should the battery be removed from the vehicle, follow the instruction in Sec- tion D, step 6 and Section G. Plug the power cord into the AC outlet.
4.Set the charge rate switch to the desired charge position. See Charge Rate Charts.
5. Set the timer from OFF position to desired timed charge, 30- 135 minutes.
NOTE: These battery chargers are not automatic and can over- charge a battery if permitted to operate for extended periods of time. Monitor the charging often.
