Charging Lead-Acid Batteries
WARNING: Before you start to charge batteries read the “Important Safety Instructions” on page (1)
and take all safety precautions when working with batteries.
The
Intelli
SUPPLY has been designed to provide fully automatic recharge of 12V, 14V and 16V AGM and gel-cell
batteries.
To charge your 12V, 14V or 16V battery:
1) If possible, disconnect all loads from the battery, by removing battery cables, opening a
disconnect switch, or switching loads off.
CAUTION!
Although this is best, in a racing environment this may not be possible. Supplemental
loads such as an electric water pump or cooling fans may be operated while charging
during stage one. Please note though that supplimental loads will reduce the amount of
amperage available to the battery. The charger detects that a battery is fully charged when
its charging current drops below a preset limit in a specific elapsed time. The presence of
electrical loads on the battery will interfere with this process. Therefore when the charger
is in stage two-absorption charging it is necessary for the battery to be isolated from loads.
The Intelli
CHARGER
is in stage-two when the charge rate is declining.
2) Select the correct battery voltage.
3) Connect the red positive (+) clip of the charger cables to the positive (+) terminal of the
vehicle battery.
4) Connect the black negative (–) clip of the charger cables to a solid chassis ground. If this is
not possible, connect it to the negative (–) battery terminal.
5) Flip the power switch on the front panel to ON.
The microprocessors will analyze the battery and then after a short delay, the charging status
LED indicator will turn red beginning the three-stage charging sequence.
CAUTION:
Do not change the voltage type during charging. Use the correct battery type at all times.
During stage one-bulk charging, the amperage will begin at 0A and finish at either 15A, 30A, 60A,
or 90A depending on which PSC model is being used. During stage two-absorption charging, the
amperage will start to fall to zero as the battery comes up to 100%. When the charging process
is complete, the charging staus LED indicator will turn green. The cooling fan inside the charger
wll come on for several seconds when the unit is initially powered up and connected to your
battery. The fan will turn on automatically when the unit reaches 6 to 7 amps and will remain on
until the unit falls below 6 to 7 amps.
*Note that the charger will automatically restart the charging sequence if the charge current rises
above a factory preset threshold.
6) When complete, flip the power switch to OFF.
7) Remove the black negative (–) clip and the red positive (+) clip from the vehicle’s battery terminals.
