Thread: Fridge and batteries

waeco's have a low voltage cutout from memory, i don't own one but you might want to check what thy are set at

i have engels and they do not have low voltage cutout standard so they caN/will leave you stranded......in saying that captain rightfoot ran his 40L engel on his first desert trip using only one battery, he was travelling with other cars but never needed a jump start

Looking at the specs, the current draw is

2.1 amps/hr average

So a 10 hour overnight will draw 21 amps (in theory) and you have a ??? amp/hr battery - if it is a good 85 - 100 amp/hr battery yes you should be good overnight.

Yes you would need a short run during the day to top your battery up - but not for long - maybe 20 mins.

The older Waecos ( like mine ) have three positions for the low voltage cut out ( hi, med and lo ). Before you go away, I'd suggest you do a test. Set everything up in the car, set fridge to the "med" position and run the fridge till it cuts out. If you still have enough juice to turn the starter motor, well and good. If not, you will need to set it to the "high" position.
( I'd be trying this while you still have someone nearby who can give you a jump start if needed. )

I don't think the newer Waecos have this selector switch so maybe it's not selectable, or adjustable in software ??

Will my normal car battery be OK to power the fridge overnight. Should I start the car every day??

I wouldn't do it, but, if the new battery is the same spec as the original Delfi Calcium battery with 900CCA 110AH and you have the fridges battery cut out set too high which will stop it drawing power at 12volts then yes it should be OK.

The Waeco 110lte draws a lot of power, far more than the 40l or 50l jobbies, even though Waeco shows they don't, in the factory they might be good, but out in the bush the elements change things alot.

Remember the Disco TD5 needs a higher CCA and Amp Hour battery too the Defender and some battery places and organisations don't know this.

Get one of those Supercheap jump packs and run it off that overnight

Baz.

You should be ok runing the fridge over night with a short run the next day but for peace of mind id get a jump start pack just incase or run the fridge solely from it i have one of theses in the link and it will run my fridge for up to 2 days depending on conditions and settings on the fridge

Tho you should be able to get this same item for 100 bucks or cheaper from any battery world or auto pro i payed 99 bucks for mine 5 years ago and its been a verry handy unit and still is

I have a charger and as I will be on a powered site, was going to run the charger overnight while the fridge is running.......

Considering the amount of imobiliser issues myself and others are "again" having on our D2's at the moment, I'd be cautious of putting any major drain on the battery overnight. It can lead to a world of hurt.

Also, make sure your power socket in the cargo area is in good condition and/or replace it with a more suitable unit (one that doesn't fall out on route) to power your fridge.

In that case why don't you just take a 240V extension lead and plug the fridge straight in to ther mains ?
