Q. How do I wire the charger to my 24-volt or 36-volt battery system?

A. Our waterproof chargers are designed to charge 12-volt batteries within a 12/24/36 volt system. If you have a waterproof battery charger (ProSport or ProMite) and you want to connect it to either a 24-volt or 36-volt system, just connect one set of leads (positive and negative) to each battery in the system. The leads are fully isolated from each other. Do not disconnect the jumper that connects the positive from one battery to the negative of another battery. The same goes for batteries in a 12-volt system.....just put one set of leads (positive and negative) on each battery. A 2 bank charger charges 2 batteries, and a 3 bank charger charges 3 batteries. Our weather resistant ProTech-C Series is a single output 24VDC or 36VDC charger and is meant to connect across the series connected batteries.

 

Q. Can I connect the charger to only one battery? What do I do with the unused leads or terminals?

A. If using our waterproof charger to charge 1 battery on a 2 bank charger, connect both leads on the single battery. If charging 1 or 2 batteries with a 3 bank charger, connect all the leads on the 1 or 2 batteries. At no time should the charger be run without all the leads being connected to a battery(s).

 

Q. Where can I mount the charger?

A. Follow the instruction manual, but adequate spacing and ventilation are generally required.

 

Q. Can my charger be left on for an extended period of time?

A. Yes, our chargers have a “float” mode that provides a constant float voltage to the batteries after they go through a full charge cycle. As long as the batteries are in good condition and you maintain your water levels (in lead-acid batteries), then leave the charger on without any detrimental effects to the batteries.

 

Q. Can I charge a lead-acid battery and a gel-cell battery together?

A. Our chargers charge and float lead-acid batteries at a different voltage than gel-cell batteries. Do not mix battery types. It will compromise a battery if you charge at the wrong voltage.

 

Q. What does it mean if I have a blinking light?

A. If you are seeing blinking lights, one of two things would be occurring.

  1. There could be a problem with your charger.
  2. There could be a problem with your battery (even if it is new).

The first thing to check is to see that the polarity (negative and positive) has not been reversed. If they are set up properly, then disconnect the leads from the batteries and turn the charger on. You should get a solid green light and the output of the charger should be at the rated DC voltage output. If the light(s) still blinks then there is a problem with the charger. If you get a solid green light the next step is to isolate each of the batteries. Check and/or replace the batteries if any are determined to be weak or defective per the battery manufacturer’s instructions. Re-connect the charger to the known good batteries. If the lights blink then the charger is defective and will need to be replaced.
