24v Batteries

Garry,

You require 24V and a 700 amp CCA. To achieve this your battery or batteries will still occupy roughly the same volume as your present ones are using. If you can find a 24V battery to do the job it will be roughly twice the size of one of your present 12V batteries. It will be twice as heavy too, and being a rarity, more expensive than a pair of 12V ones. Don't think it's a good idea!

I both agree and disagree with what the previous poster says.

lots of the 4wds that came fitted with 24 Volt systems, had twice the battery capacity of the similar vehicle fitted with a 12 volt system.
The 24 volt systems being fitted for increased reliabilty and compatability with bigger trucks in the same fleets.

So the increased battery capacity may not be necessary.
If you know there is a similar model with a single battery 12 volt system you may in theory get away with it...but in practice it may not be that simple.

Most 4wds and small to medium trucks use N70 form batteries, about 175mm wide adout 200mm high and about 300mm...and no matter of the brand or model, this about the best bang for bucks 12 volt battery size on the face of the plannet.

AND the manufacturers work arround that, that is why you will almost certainly have two 12v N70s under your bonnet now.

The problem is that a 24 volt battery in that size wont be common and likewise 2 batteries half that size that would convieniently fit.

depending on what vehicle you have what your options are.

my brother had a 24 volt MQ patroll, and he was running 3 batteries under the bonnet of that......but there is plenty of room under the bonnet of those....but all these modern cars are pretty crowded under the bonnet.

If you have a look arround, ther might be room to fit a longer battery tray somewhere an fit 2 smaller batteries..but I don't like ya chances of getting them into an existing tray.

cheers

Is it feasible to convert the vehicle electrics to 12V?

Thanks for all the comments - I take it that no one knows of a 24v battery of about the same physical size as a standard 12v car battery.

I have long ago looked at alternative options such as converting to 12v, tapping off one battery etc but these are not options for my vehicle. The issue is that 2x12v batteries take up a bit of space and if the job could be done by a single 24v battery that would be better.

24v batteries are available but I have only seen them in some small aeroplane's.
Very expensive and only lowish cca's not at all suitable for 4wd.
