Charging Your Batteries
The ProMar1 DS Series is designed to charge, condition, and auto maintain your batteries during
short or long term periods of storage. Please follow these steps each time you use your ProMar1
DS Series Charger:
1. Read manual and all warnings.
2. Review "Preparing to Charge a Battery” on page 6.
3. Ensure charger is installed as per the installation instructions.
4. Connect a heavy duty UL approved extension cord to the ProMar1 DS Series charger first.
After connecting the extension cord to the charger, proceed to plug the extension cord to a
nearby 120 VAC GFCI protected (Ground Fault Circuit Interrupt) outlet. Anytime power is
applied to the ProMar1 DS Series the blue AC Power LED will illuminate.
5. The red Charge LED for each battery bank will illuminate indicating the charger is in
Analyze mode.
It should be noted, Analyze mode can take up to 15 seconds as the
ProMar1 DS will do a self test to check wiring connections and make sure the
batteries are > than 4 VDC and are able to take a charge.
Assuming there are no battery faults, the following charger operation sequences
will proceed:
Note: If there is a bad connection, reverse polarity, or a battery that is below 4 VDC that
can not accept a charge, then a RED Battery Trouble status LED will illuminate for the battery
that requires attention. See page 23 for further troubleshooting details.
6. The red charge mode LED for each battery bank will remain ON indicating the charger has
started its multi-stage charging process as outlined in the Multi-Stage Charging Overview
section of this manual.
CAUTION HOT SURFACE.
Avoid contact during charging operation as unit will be hot to
the touch but operating safely and properly.
7. When the charge process is complete (or if your batteries are fully charged when you apply
AC power), the green Auto Maintain (Energy Saver Mode) LED for each battery bank will
illuminate indicating your batteries are fully charged.
Note: The above applies to each individual charging output. Timing of LED status will vary
from battery to battery based on discharge state of the battery connected.
