battery saver

Gramps, Mine has this function... because I'm a senior with obvious mental problems I don't know how to use the switch....Please explain?
I have tried using the instructions but they prattle on about hard wiring etc...

Mr Fawlty,

We all have those 'senior moments' :))))

Bearing in mind this is from the non-techo of all non-techos.

As I understand it, my CF40 has the option of cutting out at 10.4, 11 and 12 volts (Low, Med and High respectively) depending on the setting of the slide switch above the On/Off Emergency switch. Once it has cut out at the selected voltage, it will not cut back in until the power supplied is 11.2, 12 or 12.9 volts respectively.

Being a renowned fence sitter, I opted for the medium setting but I do run a dual battery system in the vehicle. I've left it running for at least three days without starting the vehicle before the fridge cut out.

If you're not running a dual battery system I'd suggest you set it on the High position to be safe.

I'm happy to learn from others with more experience in this area so don't be afraid to correct me If I'm wrong with any of this, please.

Just re-read my post and can see where it could be misconstrued (big word lol ).

The line "Bearing in mind this is from the non-techo of all non-techos" refers to me, me alone and does not refer to any other person living or dead etc etc etc.

Gramps, if it was my fridge I would use the high setting. Simply because I do not like to discharge my batteries too deeply.
Others may differ but that is my (electronic techo) opinion on this.

Thanks Klaus.

Always happy to take advice from people who know what they're talking about. I'll change mine and see how it goes.

I don't own a Waeco so can't check their handbook but I would suggest the following:

Single battery and camped by yourself - 12V setting
Single battery camped with someone who owns jump leads - 11V setting
Dual battery - either 11V or 10V4.

10V4 is the _very_ lowest you should discharge a battery to. I would probably select 11V unless I had some really important stuff in the fridge (decent wine etc :) or were using it as a freezer and would prefer to empty the battery before loosing the fridge.

The less you discharge a battery each time the longer their lifespan.

Hmmmm does this mean if you never discharge it, it will last for ever? :)

Mostly agree with MIke's comments.

Personally, I wouldn't go below the 11 volt setting.

On a 12 volt battery, 10.5 is dead flat and you would soon ruin the battery.

11 is better, but still a bit low.

Shaker has the better suggestion, use the Projecta "Sure Start" Over Discharge Protector.
The cut out voltage is 11.6 volts, or about 25% of remaining battery capacity and that's about as low as you should go.

So the consensus is to use the High setting on the fridge (Medium in a crisis) or get a Projecta unit if the fridge does not have the battery saver feature.

Thanks guys, appreciate the advice.

Hope your question has been answered Jilted :))))

Hi guys,
thanks to everyone I believe I have enough advise to last a lifetime. I even may have fueled a few fires!!!!
