Calculating Charge Time - Proseries PSW-2035 Guide D'utilisation

1. Set the charge rate selector switch
(switch #2) to the OFF position.
2. With the charger unplugged from the
AC outlet, connect the charger to
the battery, following the instructions
given in section 6.
3. Plug the charger's AC power cord into
the AC outlet.
4. With the charger plugged in and
connected to the battery of the vehicle,
set the charge rate selector switch to
the ENGINE START position. (Switch
#1 should be toggled up and switch #2
should be toggled down.)
5. Crank the engine until it starts or 3.5
seconds pass. If the engine does not
start, wait 3 minutes before cranking
again. This allows the charger and
battery to cool down.
NOTE: During extremely cold weather, or
if the battery is under 2 volts, charge the
battery for 5 minutes before cranking the
engine.

13. CALCULATING CHARGE TIME

When you know the percent of charge and
the Amp hour (Ah) rating of your battery,
you can calculate the approximate time
needed to bring your battery to a full charge.
Example:
Amp hour rating = Reserve capacity + 16
NOTE: The Reserve Capacity can be
obtained from the battery's specification
sheet or the owners manual.
To calculate the time needed for a charge:
1. Find the percentage of charge needed.
2. Multiply the Amp hour rating by the
charge needed, and divide by the
charge rate.
3. Multiply the results by 1.25 to find the
total time needed, in hours, to bring
the battery to full charge.
4. Add an additional hour for a deep-
cycle battery.

6. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
7. After the engine starts, move the
charge rate selector switch to the
OFF position and unplug the AC
power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry
location.
NOTE: 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.
GENERAL CHARGING NOTES
Fan: The charger is designed to control
its cooling fan for efficient operation.
Consequently, it is normal for the fan to
start and stop when maintaining a fully
charged battery. Keep the area near the
charger clear of obstructions to allow the
fan to operate efficiently.
Example:
Ah rating x % of charge needed x 1.25 = hrs of charge
Charger Amp setting
100 (Ah rating) x .50 (charge needed) x 1.25 = 3.125 hrs
20 (Charger Setting)
100 x .50 x 1.25 = 3.125
20
You need to charge a 100 Ampere hour
battery for a little more than 3 hrs at the 20
Amp charge rate, using this example.
Use the following table to determine the time
it will take to bring a battery to full charge.
Ah – Ampere Hours
CCA – Cold Cranking Amps
RC – Reserve Capacity
NR – The charger setting is NOT
RECOMMENDED.
The times given are for batteries with a
50% charge prior to recharging.
