Battery Type Selector Switch
All ProTech-C Series Chargers employ a user selectable battery type switch that is factory
set for flooded (Lead Acid) battery(s) [Profile 1]. Please confirm the appropriate battery type
and the orientation of selector switch before use. The ProTech-C has a switch cover to
enclose the battery type and the programmable timer switches. This should only be
opened/accessed by qualified service personnel.
In order to change the factory setting from flooded (Lead Acid) [Profile 1] to Profile 2 or 3
(see page 8 for general recommendations), simply remove AC power to the battery charger,
and locate the user programmable battery selector switch on the DC end of the charger.
Shown below you will find the three battery type configuration settings that are used to
program the 3 position dip switch as illustrated. Choose the correct setting for your battery
type.
If you are unsure of the battery type, please refer to “Selecting a Charging Profile &
Understanding Battery Types” on Page 8.
Once your ProTech-C is programmed for your battery
type apply AC power. The Battery Type LED will illuminate indicating your selection.
Note: If more than 1 battery type is illuminated, recheck you battery type selector switch
positions as illustrated above. It should be noted, only (1) of the 3 switch tabs can be in the
“ON” position for proper selection and operation.
The ProTech-C Series is equipped with a programmable absorption timer switch that places
the charger into the absorption / conditioning mode for a period of 2,3,4 or 6 hours as programmed
and indicated by the switch selection. The factory setting for the timer switch is 4 hours.
Determine the best absorption / conditioning time either by obtaining your battery manufacturers
recommended specifications or by using the guidelines below. The illustration below depicts
the 2,3,4 or 6 hour switch configuration settings that are used to program the 3 position dip
switch to the desired length of time.

Selecting a Charging Profile and Understanding Battery Types
There are three primary types of batteries; 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).
Almost all GEL Cell Batteries will state that they are GEL Cell on the battery case or labels.
ProTech-C series chargers are designed to allow for the following three (3) battery chemistries.
The most important element in selecting a proper profile is to mate up the voltage selections
available in the 3 profiles to that of the battery based upon the battery manufacturers requirements.
For your convenience, we have incorporated 3 major profiles associated with some of the
most common battery brands. These profiles can be used with many different brands and we
suggest you contact the factory if you are unsure as to which profile to select for your application.
It is very important to select the best match as this will impact total battery cycle life! It is also
fundamentally important to neither over or undercharge your batteries. See the chart on Page
8 for some general recommendations. The Profile Battery Selector switch allows the charger
to be compatible with multiple battery technologies (Flooded Lead Acid, AGM and Gel).
Programmable Absorption Timer Switch
***IMPORTANT!*** If you are unsure about which of the 3 available profiles to choose
from, consult with the factory. Incorrect selection can result in permanent damage and under
or overcharging of the batteries.
NOTE: AGM (Absorbed Glass Mat) batteries are not GEL (Gelled Electrolyte
Lead-Acid) batteries. AGM batteries are charged at different charging profiles
and are not the same
