I have a Dolphin 12 V 80 Amp charger approx 3 years old. I have just changed my house batteries from Flooded Lead Acid to Full River AGMs. I believe that my charger settings now need to be changed suit the AGM batteries. However there are no obvious setting adjustments on the charger that I can find and no description in the handbook about changing settings.
Can anyone please help?

Greetings and welcome aboard the CF, Geoff .

Apparently, the Dolphin chargers have about 10 differing (selectable) charging profiles. Check out (or ask) which most closely matches the FullRiver specifications.

Thankyou GordMay - I know what setting I need to be on but it is not clear in the manual how or where I make the changes to that setting. Any further suggestions?
Cheers Geoff

Well I read the manual from cover to cover and...it beats me!!

I found the "Charge Selector" switch but no indication regarding what program you have selected. If I were you, I would remove AC power, wait about 30 seconds, apply AC, change the "Charge Selector" one position and try and discern some indication on the LED display. Repeat. Possibly this will provide a pattern and a clue.

Let us know what you figure out.

I have Dolphin 60 charger fitted to my boat.
It has a small unlabeled switch inside near the bottom when you unscrew the cover.
I used a calibrated multimeter to check the voltage when I got the boat, and to set the switch at its correct position.
I cruse and mostly live at anchor with solar power. I haven’t used the charger for a couple of years now so I cannot remember what the voltages were, but it should be easy for you to check. From memory it was only 2 stage (Absorption and float).
It would have been nice if they included this in the handbook.

Yes - quite some time ago but the settings you have listed seem correct to me. The adjustments are easily accessable on the charger once you know what battery type you are wanting to match. I changed the setting to AGM batteries and all seems to be going well.
