I have come to have in my possession a spare 12V battery (accidentally bought the wrong one for my car and couldnt be bothered taking it back)
Now does anyone know is there any point in me shoving it into the passenger side locker box on the unit and wiring it up to something like a tv, or microwave.
I would presume id have to find to some way to wire it from the alternator as well? So it doesnt just run itself flat. Or how long would i get out of tv / micro usage before I had to sya charge it with a portable battery charger.
get a 24 volt invertor - run a 12 volt charger to the battery - use a nice one like a C-Tek that conditions the battery and you can leave it connected - it will then run all your 12 volt stuff
cheers

Would love to hear nay suggestions please
Thanks in advance!
Stick it on Ebay or Freecycle, would you really want a loose battery in the side locker

lol, mmm, tricky one that, carry a spare 12 v battery, then buy and carry around a 24 v inverter to convert to 240 v then buy and carry around a battery charger to charge a 12 v battery surely there is a simpler way of running 12 v than this:D

If someone is going to get an inverter wouldn’t it be easier to just use that to run their various items?
A lot of people seem to miss the point that its so easy to pick a feed up off ONE of the trucks two 12v batteries. Heck, you can even jump start a truck from a car.
OP, whilst you’re thinking what to do with it, whatever you do don’t leave it stood on concrete or it will be buggered in under a week.

I used a car battery to jump the truck a few weeks back. My last truck had a dodgy outer battery that just needed a bit of a boost. It wouldnt start when I had a long park up in portchester so I went to the car spares shop in the village and asked for some help. The guy came round to the lorry park in his car with a brand new car battery, I connected it to the dodgy battery and the truck started no problem. I gave him a tenner for his trouble and we were both happy

It is easy, but employers don’t tend to like drivers doing it, for perfectly good reasons; best to get a fitter to do that sort of thing.
As to your second point; this was indeed the case many years ago, but it’s ancient wisdom handed down which does not occur with today’s modern batteries. See here;
Hmmm, American article eh. Not generally known for being the brightest button in the box are they?
Certainly wouldn’t allow any batteries I owned to be stored on concrete.
A friend who is a dairy farmer lost 2 truck batteries in recent times due to this. He diversified into chicken rearing, had 2 big broiler houses erected with auto feed & lighting systems, etc. Large diesel standby genny, auto start, 2 x heavy duty batteries sat on the concrete floor. They lasted under 2 months. The replacements, set on a timber still, have lasted years.

I picked that article from many which came up when I Googled “battery on concrete”, just looked back and all those written by qualified people say the same thing i.e. it’s something that used to happen way back when but is no longer possible because of modern battery manufacturing techniques. I was apprentice trained as a vehicle mechanic in the Army on the 1970’s, spent a few days on a course teaching me the ins and outs of batteries and I do not remember seeing such advice as you gave.
But of course you know better because all Yanks are thick… tell me, do you switch off an empty socket in case the leccy leaks out?

Taking a 12 volt feed from one of your main batteries is a bad idea, it will disrupt the charging of your main batteries and cause there early demise.
Driveroneuk:
Really? So how is the radio, if its a 12v and any 12v sockets fed from new then?
By a voltage dropper from the main wiring loom. And bazstan, do you have any documentary evidence to back up your claim? I wouoldn’t have thought it would make a deal of difference UNLESS you’re running appliances which draw a high current which would leave one battery in a considerably lower state of charge.
Would welcome some input from a qualified sparks on this one, think it’s heading into MMTM territory.

I read up on this a while back before fitting extra batteries to mine I will find the info I used and post it buy maybe not til home.
surely there is a simpler way of running 12 v than this:D
