Vevor 55l fridge how long would a leisure battery last

[F2JON]

As title, I have a vevor 55l fridge , I just wondered how long it would last if I hook it up to a leisure battery, going to camper jam this weekend just wondering wether to take it or not, here’s the specs if it makes any sense to anyone

It depends:
The fridge will pull a max of 5A when on...
The fridge cycles on/off dependent on the temp you have it set to and the ambient air temp. The default hysteresis is 2 degrees.
So for example you set it to 0 degrees, it'll cool to -2 and switch off, when it gets to +2 it'll switch on and cool down to -2. Meaning an average of 0 degrees.
The speed at which this changes will depend on what's in the fridge and the ambient air temp (warmer = more quickly)

I have a coolbox which constantly draws 4~5Amps and that flattens a 75ah battery in ~14 -16hrs. I've just replaced this with a Vevor (45L) and I'm expecting around 48hrs.
The Vevor does have low voltage protection for your battery to prevent you killing it. Also The fridge will work as a coolbox if/when the power is off (so maybe turn off/down at night if it's going to be colder to ensure cooling during the day) - set an alarm to remind yourself to turn it back on in the morning.

brilliant thanks for your reply

What he said.

You should be able to get two days from a 100ah LB.

How do you charge you LB?

Dc-dc charger?. Solar?

I was borrowing a leisure battery off a mate I haven’t installed one in the van as I barely need one as I have a hook up normally.

Ok.

Well enjoy CJ.

Keep the fridge full of beer and set the temp 1-5degC.

That will help it to run most efficient.

I intend to I’ve filled it with beer ready to rock

Chuck some freezer blocks in there to get the temperature down when you first turn it on

Chill the beer at home first. Water has a huge thermal capacity, if you fill the fridge full of ambient temperature beer, it’ll take 12hours or so to get it down to temperature, & the fridge will be running flat out during that time.

Chill the beers at home first as this will help cool the Vevor when you load it and reduce how hard it has to work to reach the desired temperature.(helping to prolong the battery life)

Great minds! You beat me too it!

Don't forget @JOG 's frozen chilli

 

[Dellmassive]

Yes. Defo pre chill the whole full fridge at home down to 1degc , then plug it in for the drive to a 12v socket in the van, if you can.

Then when onsite. Set the temp to 4 or 5 themmn move to over to your leisure battery.

I've used this before I had 240v in the van while driving.... Plugged in the front socket. And had the fridge behind the seat.

Fridge only draws 6A ish intermittently.... So that cable worked fine.

Now I've got perm 240v in the back...
So I run the fridges off that when travelling to site...
But alway pre chill at home.

The only problem is that the fridge is then super heavy when full off beer so it takes both me and the cheif advisor to get it into the van.

Yup already got one of those ready to rock, thanks every one for the advice hopefully I’ll have cold beers all weekend, oh and a bit of food
