New battery losing water with new 3 stage Professional Dynamics 9260 Charger

Just had a new 3 stage charger installed by my mechanic and I'm using it for a weekend trip.

I checked the batteries earlier (brand new Interstate 12V group 27), however, and the tops are wet and have clearly been bubbling up acid.

I was thinking the new charger and new batteries would prevent that. Not sure how to trouble shoot this.

I have an watering system (qwik-fill) for the batteries. I am wondering if it is filling them too full? It's a bit frustrating...

I would think that a new battery would be full of water and not need more. If your Dynamics is putting out too much voltage it can heat up the batteries. I would check the voltage coming out of the Dynamics and see if that is not the problem. Hope you get it working

How many batteries do you have? Did you replace all of them at the same time? Changing one or two from a set will cause charging problems.
Best way to troubleshoot is to take your multimeter and check the voltage across the Pos and Neg terminals. When plugged in to shore power you should see 13.6 - 13.7 VDC Maximum. If it is higher, you have a problem with the converter or a faulty battery.

Are the charging parameters of your new 3 stage charger adjustable?
If so are they set correctly?

BTW: only add water to the battery electrolyte up to the correct level, (and only when the batteries are fully charged).
If the cells are filled when the charge is depleted it's not unusual for the cells to overflow while charging, (via the on-board charger, the alternator, or an accessory charger).

It could be the batteries are over filled. I have the same Progressive Dynamics converter/charger with Profill battery water system. My batteries always stay clean and dry since installing the Profill. Only other thing would be the converter is over charging the batteries. If you have a volt meter check the voltage at the batteries with the charger on. If it is over 15 volts there maybe a problem with the charger.

Maybe this explains the problem. They needed quite a bit of water when I brought them home new from the store. I heard many batteries ship that way so I filled them up and charged them.

I then put them on a separate charger and noticed only a little boiling off.

After my trip here I noticed more, and I was thinking maybe the alternator was over charging a bit.

Since being here and plugged in I am noticing what I think is even more, even though the charger seems to be working...right now it is on maintenance at 13.2V. Also, I see water on the top of the batter but don't see any bubbling out of the holes, so maybe it was from the alternator....

Thanks for all the comments!!

Also, I have two house batteries that were replaced new at the same time.

You could remove the excess acid with a turkey baster or just keep cleaning up the tops of the batteries till it stops boiling over. Just be safe, use gloves and face shield or goggles when working with batteries.

I was going to say that a 9260 is too big for a SINGLE Group 2, it is, however, precisely the recommended size for 2 of them in parallel. (Source Xantrex manual for my Prosine 2.0)

Batteries may have been overfilled,, Though many say "To the bottom of the split ring" or "To the bottom of the filler tube" including many battery professionals... The proper level is 1/8 to 1/4 inch BELOW the bottom of the split ring/filler tube This gives them a bit of head room.

Also the level my go up a bit when the batteries charge.

So for now wash 'em off with soda water, then clear water (Baking soda and water all the water will hold of soda).

Then when you re-fill 'em fill to like half way between plates and filler tube, Charge, Fill to 1/4 inch below in that order.. I need to check mine soon thanks for the reminder.

Looks like I should have added water and charged them fully BEFORE adding the qwik-fill system. It says that on the qwik-fill instructions, once I got around to reading them... :-) Now that the excess water has boiled off, everything works like a charm. Thanks, everyone, for the great advice!
