Battery Charger not charging

The one i have is the same as yours, but allows up to 30 charging amps instead of 20. What kind of batteries do you have setup to that charger?
 
Thanks @radscoot I'm curious what the best solution is then. I knowingly don't know much about batteries, but from what i've read, house batteries are best to be deep cycle while cranking battery is best to be AGM. Do most people use two battery chargers? Or is it fine to use AGM for house batteries? All of a sudden i'm more confused than before.
Flooded Starting batteries are just as strong as AGM’s. Deep cycle can be Flooded or AGM. The difference is the AGMs are maintenance free where as flooded requires an occasional check to make sure fluid levels are topped up.
The AGMs are generally more expensive so it depends on your budget. My Boat came with Flooded batteries and when I had to update my house batteries I used the same. I also use the Pronautic charger.
On my Harley’s and my car I use AGMs.
If my boat had come with AGMs I would have carried on that way.
Hope this helps.
