Does anyone run their fridge all night without generator on while anchored? Will my batteries be ok?

Yes I do with no worries I have 4 batts . I also carry a 1000w genny just in case !!.
If I do something stupid like leaving the cabin lights on all night also . :smt021.
 
You need to know how many amp hours your batteries have. I have 232 amp hours and my fridge when on draws 3.5 amps. The draw is only while it is on but I am good for a long time at that draw. My anchor light draws 2.5 amps it is harder on the batteries than the fridge. It is also down into the 60's or the 70's at night in the summer here not sure about your area.

Off for me. Something I found that helps is if you put a tray of ice in there it keeps them cool through the night. I find those fridges a bit on the noisy side so I prefer to turn them off even if the batteries aren't an issue.

I run both my refrigerators all night, it is the days that use the most power for me while out, the door opens up a whole lot more letting all that cold out each time.

My port two batteries run the port engine and all the house stuff. They were the first to go but made it nearly five whole seasons. Seriously though I have never had any battery issues from the fridge. I run high power amps, subs, etc. When my batteries were failing last season, I had to use the emergency battery dashboard switch once to start, at that time I knew I needed new batteries.

I do... but I installed two additional batteries just for the fridge :wink:

If you have a genset do not forget that it will be of help in a battery emergency case, only if it has its own battery isolated from the others!
 
Yes. On one group 27. The more food you have in it (already cooled), the less it will kick on. I think another 3 to 4 hours would be enough to not allow me to start the engine on that battery, though.
 
I appreciate all the feedback/. I have Satellite Tv so I will probably have generator on until I quit watching tv so it sounds like I dont have anything to worry about. we always sleep at dock with shorepower, but now we want to wake up with some different scenery:grin:
 
I found that turning the fridge on it's coldest setting a couple hours before bed while the genny is on, then @ bedtime and genny off... turn it on it's lowest setting works well. I keep lunch meat etc. and don't want to eat anything spoiled for the sake of a little effort.
 
Start the engines b4 bed to re-charge them for the night as well. then fire them up in the morning same purpose. Once you do it a few times you will feel more comfortable. Good luck
 
We freeze large plastic deli containers full of water. One of these goes into the fridge just before bedtime and then we turn it off. We're also in the 'its too noisy for sleeping' camp as well. In the AM the ice goes into the ice bucket up top in the wet bar.

I run em' both without issue but have more confidence with a charged DC jump pack on board.....even with a genny.:thumbsup:
 
Our boats fridge gets turned on in spring when we splash and turned off in fall just before we pull the boat. The in between time it’s left on.

We anchor overnight often.
 
I switch to just one of my two deep-cycles, turn the fridge to a lower setting like 3 or 4 and agree it helps to put in a frozen bottle of water. Runs all night.
And, I don't like the noise.
 
Go for it you'll be fine. I have never turned my fridge off during the season. This includes 4-5 days on the hook. Although, if you do have a genny it is nice to run that to juice everything up.
