Two years ago I "treated myself" to a 12v cool box (without mains adapter) which I've used on a number of short camping trips (2 nights) with some success ...

This year, amongst others, I'm planning a 7 day trip in a field in Pembrokeshire (stand pipe only).

Given the length of stay, lack of electicity and fabulous weather I decided I'd finally invest in the leisure battery my cool box instructions said I could connect to. The only thing is, I've now lost the instructions and can't see how I'd connect the battery and the cool box.

Maybe I'm being dim .. can anyone help explain it to me!

You might have to fit crocodile clips to the fridge lead or make up some kind of adapter cable to fit whatever plug type you have on your existing cooler box cable.

Hi, this would be your easiest way...click here to buy

wow....Did'nt think you can buy them, this is what I would have suggested to make.

Don't give up just yet - a car battery and a leisure battery are two entirely different beasts. The car battery is designed for short duration, high load (such as starting a car  ) while the leisure battery is the opposite - long duration, low load - for things such as lighting, 12v tv etc. If you have already got the leisure battery it would certainly be worth having a go and seeing how long it would run the coolbox for. I have (accidentally) left my coolbox connected to the car for 7-8hrs in the past and it's started fine. I'd guess that a leisure battery would run it for a few days.

One word of warning - don't buy a lead that includes a voltage protection cut-out device (used to prevent items flattening a car battery), as this needs the voltage from a running engine/alternator to keep it going. Even my fully-charged leisure battery didn't have the necessary 'oomph' to overcome the cutout device.

Post any results you get from the leisure battery, i'm sure there'd be some interested readers.
