I have several of the UB12750 batteries. I am trying to come to a conclusion if these are acceptable batteries to use with the 30A Wonderer Charge Controller and what mode the controller should be placed in. Should I be setting the system to GEL? The instructions are not real clear on this.

Thanks,

Chris

The reason I ask is because I feel I ruined two of these batteries with this older 30A PWM controller which I believe was equalizing the same kind of batteries over a year period. The batteries were new and their capacity dropped to around 10% after only a year. I bought a new controller and want to make sure the settings were correct.

You know it could be more that you drained the batteries to much..........

Way more info is needed to give you a better explanation..........

I agree and I just don't have that information because it is at a location where others are able to discharge the batteries for charging their R/C airplane/heli batteries. They may have over discharged them while I was not there although that old controller did have a low voltage disconnect which I hoped would prevent that from occurring. The new unit does not so I need to find another way do do a low voltage disconnect.

That one is very small..... Tell us how many panels you have and more about your system.........
