What CCA battery for V8?

[DeeJay]

Our '95 Disco has been cranking over slowly lately. I cleaned the terminals etc but today it refused to start. The RACV called out ( I was at work) and tested everything saying it was a faulty battery- not holding its charge.
He spoke to my wife and looked up a V8 Disco battery in his book and it says 800cca.
The battery in it aint that old- probably less than 2 years and its an exide 550 cca extreme- a good battery, but he says being not up to task is what killed it.
I think the book is wrong.
Any opinions??

550CCA should be adequate. Mine is 550CCA and works fine. I did replace the battery last year after I bought my Disco as I didn't know how old the battery in the car was.

Perhaps the problem lies elsewhere?

The physical size of a battery capable of 800 cca is quite large but would fit (unless it is an optima or similiar) so I expect it is less than that.

If buying a wet cell battery, I would be looking for something with a 12+ plates.

I run two N70** series in parallel. 550 is a bit small and depending what additional electrics you are running.
Combined new I had nearly 1200cca and man did it crank!!!
As both of mine are looking to be replaced as they are about 5 years old am looking at cranking deep cycles for a change.

Just need to check out the the charge limitations if any being deep cycle. Think these may be an AGM style.

MRV70 for right hand side and MRV70L for left hand.

Golden rule!

Fit the biggest bugger you can fit in there!

Always nice to have as much in reserve as possible.

MRV70 wont fit unless I re route some aircon(I think- its dark now) pipes.
The biggest size would be 290 x 175x 225
I need to start shopping around. BTW its "her" Disco- so bog standard:)

I've been running the same size Extreme for a few years as my start battery with no problems in my V8. I also run a second Extreme as my aux battery and it does a great job running the fridge etc.

The Extreme have a 2 year warranty so you might be able to get it replaced if its failed.

The battery box area should be identical to a Classic and mine fits in perfectly....

Dimensions of what I have now are 300 x 170 x 200 and I still have about 10 - 15mm left to right movement. RH side is probably a bit tighter but fits without moving anything.

Its a 3.9l low compression engine, it don't need much to crank over

But as Tombie said, fit the highest CCA that fits in the hole

If you wanna be sure, I got one, works alright

I have been running a 550cca as well.

When we crank the car sure it drains a bucket of amps but in the first 10 minutes, the alternator puts it all back as it runs at max.

Its the heat under the hood that is a real killer of batteries.
Put one in the boot with heavy duty leads and I bet it will last 5 years.

I'm using ....
Supercharge 530cca .... 2 years old.... V8efi ..... Good as gold

Visit your local CAT dealer(Caterpillar) grab a battery from them.MADE to SURVIVE in earthmoving equipment.
I got a Calcium 1000CCA for $189.00 from Westrac Guildford WA.You wont go anywhere near that in an auto shop.That was as a walk in cash buyer,no Shire worker discount!!! 5 year warranty!!!!
They are slightly bigger than the standard size but fit a D2 fine,I had to change battery lead ends to suit,but was easy and the D2 ones were stuffed anyhow.
Goodluck

Thanks guys,
I found the receipt :cool:
Well, the Visa statement anyway. March 16th 2007. So its still under the two year warranty.
I bought it two months after the new alternator so its never gone flat,- until lately anyway.
The RACV says the charge, leads, starter are all fine, so I reckon I have a pretty good case.
I think I'll go up to an optima bluetop as it claims to be 750 CCA.

The MRV series is a good unit I have a MRV87 on the left to run the fridge and other goddies and its also a simple hook up as a secondary cranker and on the right i run the same size gold series MF31-930 they both required some triming and minor mods to fit but they sure do have some cranking power and the allrounder will run the freezer for 3 days without a run to charge it back up ....

Woohoo:banana::arms::clap2:
I got a new battery under warranty today.
Full marks to Marshall batteries at Dandenong (they advertise in the Vic Land Rover Owners mag).
I took Debs Disco in after charging the battery last night and they tested it as faulty & swapped a new one quite happily.
I said I'd like to upgrade to a bluetop & the manager said I would be wasting my money. It appears they rate thier batteries @ minus 18 deg celcius and the 550 CCA thumps out 850 at ambient temp and a bluetop would be sending a man on a boys job.
I could'nt be happier with the service & advice.

Part No looks to be 175-4390,unless some is covered by the battery clamp.Cant give sizes without removing,it isnt much bigger than a standard 4WD battery.Sizes are on the website.
Search Cat Bateries on Google,P.S its much easier to use the US CAT site,you need to register to use Aussie CAT sites,go figure!!!
