Ok....but behave yourself this time

It would be extremely foolish to buy those expensive AGM batteries unless you provide a means of looking after them. They can be killed off just as easily as cheaper lead acid batteries.

Those ones are very reasonably priced......hence my interest. Also the capacity is good and the footprint is perfect

Edit: Don’t do that. It’s one way. Battery protect needs to be in front of the loads only.
It’s madness that Jenneau don’t fit one in the factory

Do we know they didn’t ?......there’s one or two electronic components that I haven’t bothered to identify

But is it more reasonable than your upcoming elective surgery?

Well if they had fitted one, your batteries wouldn’t go completely flat.

What would they go down to ?

Whatever you set it to, but normally about 50% if you want your batteries to last.
That way, if the fridge is left on, you can just charge the battery back up rather than replacing it.
Discharging a battery past 50% has a massively detrimental effect on its life and subsequent ability to hold a charge. If you discharge it to completely flat and leave it there for any length of time the battery will be completed junk.

I will see if one is fitted next visit

You make giving useful advise virtually impossible. It's been suggested that you fit a battery protect by more than one person and told that there cannot be one installed because the batteries are allowed to completely discharge.
Your answer to the problem is to fit smaller batteries but leave then in an installation where they can be 100% discharged and ruined. A "solution" that cannot fix the issue and costs more than actually fixing it !
Frustrating.

I actually said that I will check next time I visit the boat if it already has a battery saver....this isn’t something that I had heard of before....if it doesn’t have one, then I can investigate how to install one

You could arrange for your fridge to switch off if the pontoon power is removed. That saves your batteries at the price of wasting some food.

How is that possible ?

For me, leaving the DC switched on whilst we are away from the boat is a No No No No
If you must have a fridge on whilst you are away, why not arrange for it to be powered by the shore supply.
All mine are.
Waeco supply fridge power unit that will power a DC fridge from both 240v and DC (12v / 24v).
It automatically switches from DC to 240v whenever the 240v is connected.
Use one of these and SWITCH THE DC OFF when you are away.
Then, if someone disconnects your shore supply whilst you are away, your batteries won't discharge.
When you are on board (with your DC systems on), the Waeco power unit will automatically switch from 240v to DC when you go cruising.
And then switch back to 240v whenever you are plugged back into shore supply or running off generator.
These Waeco supplies are used everywhere - they are designed for the job.
They have a few different models, depending on the size of your fridge.

I had one like that on my motor home....in fact it was three ways...gas, 12v and 220v...all seamless transitions.
So you saying that an existing fridge can be converted ?
