Thread: What CCA battery for V8?

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.

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??

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
