Battery Types
There are three primary types of batteries in the marketplace today; Flooded
(Lead Acid), AGM (Absorbed Glass Mat) and GEL Cell (Gelled Electrolyte Lead-
Acid). Traditionally, the most common type of batteries used are Flooded (Lead
Acid batteries).
AGM batteries are often mistaken as GEL batteries
Almost all GEL Cell batteries will state that they are GEL Cell on the battery case or labels.
NOTE: AGM (Absorbed Glass Mat) batteries are not GEL (Gelled Electrolyte
Lead-Acid) batteries. AGM batteries are charged at the same charging profile
as Flooded (Lead Acid).
***If you are still unsure as to what kind of battery you have, we recommend that
you contact the manufacturer of the battery.
CAUTION: When installing a ProTech-4 battery charger in a vessel with a generator be
aware the charger is designed to charge batteries of similar size. Generator batteries
are usually significantly smaller potentially causing the charger to overcharge the
generator battery. We recommend that the generator battery receive a battery maintainer
available from ProMariner.

Operation
When the charger is activated, the YELLOW Fast Mode LED and ORANGE Boost
LED will be lit. If lead acid/GEL cell switch is in GEL position, top LED will be GREEN
instead of YELLOW. (LEDs shown below)
Note: It is not recommended that you charge different battery types and sizes.
The charger is design to charge similar battery types and sizes; any other combination
can cause the charger to over or undercharge and is not recommended.
After the Fast Charge cycle, Absorption time is determined by the position of the
three timer switches. (Shown on page 4)
The ProTech-4 battery charger will operate for the selected absorption time
whenever AC power is applied.
Full-rated current is available in Float Mode. Voltage
will normally be above charged battery Voltage at
full output.
When the Voltage falls below 11.5 Volts, or if the AC
power is applied, the Fast Charge cycle will start.
Battery charger fan(s) will turn on only as needed
to control temperature, the fans will not run
continuously unless needed.
Note: for your safety the charger is equipped with an internal temperature sensor
that will turn off the charger in extreme heat.
