Red or white wire with in-line fuse to battery (+)
Black wire to battery (-)
The in-line fuse holder houses a 3 AMP fuse. If the battery is connected in reverse (red to (-), black
to (+)) this fuse will blow, and there may be no LED indication of malfunction.
WARNING
Do not cut off or rewire the DC output connector. Failure to abide could cause
personal injury and void the warranty.
Making AC Plug Connection
After securing the battery connections, plug the AC line cord into an available AC outlet that is
protected by a Ground Fault Circuit Interrupter (GFCI) breaker. Keep the AC power cord connection
as short as possible especially when using an extension cord.
4. OPERATING THE CHARGER
Proper Operation
When the 2602A-12 charger senses a drop in battery voltage, it automatically increases its output to
re-charge the battery. By using a sophisticated three-stage charging method, it can fully recharge
your batteries in the fastest, healthiest way.
During the first charging stage, known as “
BULK
” charging, most of the battery charging is
accomplished. The green LED will blink during this stage. The charging current is limited to 2 Amps
and the battery voltage rises to approximately 14.5 VDC.
During the second charging stage, known as “
ABSORPTION
” charging, the charger holds the
battery voltage at approximately 14.5 VDC, and then gradually reduces the amount of current
(Amps) it delivers to the battery. By doing this, the battery is able to “absorb” the last 10% of charge
as quickly as possible without becoming overheated. The green LED will blink during this stage.
When the battery approaches full charge, the charger switches into its third charging stage,
gradually reducing the current fed to the batteries to as low as 0.1 Amps. At the same time, it
reduces its output voltage to a “
FLOAT
” or “
Maintenance
” charging rate of approximately 13.3 VDC
nominal, indicated by the green LED light. This low “
Float”
or
“Maintenance”
voltage gently “tops off”
your batteries, keeping them fully charged and ready until needed. Now you can store your batteries
at full charge indefinitely without overcharging, when batteries are properly maintained. The green
LED indicates that your batteries are now fully charged and ready for use.
