Need a new battrey to power my 360. Alex had previously sugested diesal Transit type (?80 Quikfit!) however, Quickfit provided Ivan (440 Challenger) with the 'correct' battrey only for the alternator to 'overcharge' it and thus melting the battery. Any further suggestions or do i go for the transit battery?

I,ve found an online battery company. Can anyone tell me what ampage I need plus amp hrs figs?
my manual doesnt have these figures.

i use a jeep battery on the duster (it has MOPAR on it) but in the past i have used mondeo diesel batterys with no problems , macro do them for ?22 , i cant see a problem with overcharging if your alternator and regulator are all ok .

Trev, thanks. Have you any idea what the amp figs are for the mondeo battery? Much happier to shell out 20 odd quid than eighty but, only want to spend once. Also, is your duster an auto?

the duster is a 273 auto the battery is in the boot which uses more power , according to the haynes book it is anything between 500 and 650 amps , most aftermarket only list one , it seems ok for a v8 , its suprising how little power you need , my old 3500 rover used a mini battery and my 3ltr scimitar used a reliant robin one , if everything else is in tip top condition a small battery will work . personaly i would use the bigest battery phisicaly possible if you dont want any problems , when you buy it tell the shop its for your normal car , many warranties wont cover classic or american cars

Thanks Trev, just got to invent a 'normal' car to suit now!

buy a diesel on paper , or find a mate who has one

US Auto got me a new AC Delco suitable for SB Mopar for ?50

just paid the same from a local supplier. The guy is a yank who is familiar with our cars and has helped me out a few time. I'm back on the road again!

I am trying to solve asimilar battery problem,

I went to go and get a transit diesel battery from my freindly neighbourhood battery shop, he asked me what transit it was for to which I explained how it's actually for an old V8. I had brought the battery with me, and he looked at it a and told me it was a japanese spec battery, with cold crank of 740 and 90amp hours, and that a diesel transit battery doesn't have as much power. A similar battery was ?80 (exact same measurements and amps), Anyway he also tested my old battery and after reporting that it was reading 11.4 volts offered to give it a proper charge overnight to see if it's ok or not, explaining that alternators are designed to just replace the power used not to deep charge the battery, and that if a battery gets too low it reverses polarity, and er, gets hot (to be honest I wasn't listening properly at this point.) He also had a good laugh when I told him I had been jump starting it from my golf. Meh.

So I've left the battery with him to charge up, and maybe it'll be fine, else I'll buy the budget version of the japanese spec battery at ?60.

So If I do have to buy a new one, have I been running an overpowered battery on my 360, and a (smaller) transit job will do, or should I get the closest replacement for my old battery? ?60.

Don't forget that the more cylinders you have, the less cranking power you need. But more compression means more cranking power. HTH!

I bought a battery for a Grand Cherokee from my local Jeep dealer for ?80. Same size and configuration as stock, has Mopar written all over it, and spins my 440 easily.

i'm using a Hitachi battery that is at least 12 years old on my Dodge ! (old skool screw caps)

Worst battery i bought recently was a Fulmen, and worst ever ever ... Pavillion. (made in Brighton i believe)

Yuasa make a good batt. Also the Varta ones seem ok.

If buying a battery, pick a heavy one. Might actually have enough lead in it to be half decent!

Here's the battery(s) you need!

Kev, that's a Fuel cell.
