Dolphin Beneteau 371525 Charger

[Justin Clarke]

Hi All,

I have just purchased a Beneteau Oceanis 40 2011. I have just replaced the house batteries with two 200ah batteries. I don't know where there is a switch to change to AGM and their is a button on the side of the unit.

I get a slow blinking yellow light and if pressed I get a fast flashing Green light.

does anyone know what this means or where I could find a manual. I have sent an email to Dolphin but thought I would ask you guys?

any help would be great.

Thanks 

Jay

Dolphin?

I wouldn't recommend pushing any more buttons til you have a manual. Battery chargers normally have a small switch on them somewhere that reads:

Flood/Gel/ AGM

You simply push the selector button to the appropriate position.

Good Luck

Nice Boat

Thanks for the tip ;-)

I have a Oceanis 40 2011 built in USA and my battery charger is a Xantrex 40 amp. If you have that model I can send you the manual.

Hi thanks for the response....

I haven't had a reply back from dolphin but it's the weekend now so hopefully soon.

Yeah no more button pushing lol....

I have included a couple photos and I wish it was the Xantrex system and thanks for the offer also...

That photo shows where lines from your batteries are connected to your charger ( three red positive  (lines) from battery  and a common shared ground line. Looks like a standard  battery charger to battery setup. Now you need to investigate a little further to try and find the battery type selector switch. Is there a cover of some type that you might be overlooking on this charger? Why not have someone in the marina with a bit of experience to take a look at the charger to help you locate the switch if you can not find it.

Almost all modern day multi stage chargers have a "battery type" selector switch but maybe this is not a multi stage charger? If it's not you will need to get rid of this charger and purchase a charger that can charge flooded/agm/gel batteries otherwise you' ll probably gonna have a short service life from those pricey agms. Hope this is not the case and you can find a battery type selector switch.

Hello,

I wonder the exact batteries that you are using. My boat comes with 2 140 AH batteries and I also would like to replace them with larger capacity ones. However, the size is a problem unless I change/adapt the boxes, the wiring, etc.

Hello Jay,
I am away at the moment and cannot access my manual though I am sure if you remove the cover from the Dolphin you will find a series of jumper switches enabling switching between battery types.
AGMs will need a higher voltage than either gel or lead acid so overcharging will not be a problem.
Maintaining the correct voltage at a different or incorrect setting will be.
I will be back around the 22nd November and will have a look and come back.

I have a 2011 US built Ben 40 and installed to 4D AGM batteries. The capacity increased from 160 to 195 amp hrs no modification needed. I have a Xantrex battery charger that came with the new Boat. There is a button you depress on the charger and it will Cycle through the type of battery. Stop at AGM. A flashing yellow may be an internal fault problem. You can disconnect all Electric power to Unit for several hours or over night and see if that fixes the problem. I have been told that charging characteristics for AGM and lead acid are similar so no damage will be done. Just efficiency is lost.

I advised last year than when possible I would forward you a copy of our Dolphin Charger manual.

Finally that is now attached and you should have no trouble configuring your unit. Take the cover off to reveal the jumper switches.

As an aside our Dolphin has performed faultlessly and keeps our battery bank it top condition.
