Battery Megastore MF31-1000, it's the largest battery that will fit. Less than £90 delivered in the UK I think. My last one from them lasted 8 years and was killed by the alternator.My Optima red top has finally died after several harsh winters. My budget wont allow another atm. Can anyone recommend a battery around the 100 quid mark that will fit ? Cheers
For the past 10+ years I've relied on standard 72AH / 600CCA batteries with a two year no-quibble warranty purchased from my local auto factor. Each one has lasted over five years on a 3.5efi (same battery spec for the 200/300i models) that's only an occasional driver & has to park outside in all weathers.
I have never owned a P38 or desired one, but I can't understand why they seem to need such a large battery, after all a RV8 is a RV8 albeit with an extra litre capacity, presumably it's to cope with all the extra lecky gadgets & the parasitic drains many owners seem to suffer
072 or 069 are the only batteries that fitted my RR 3.5 and now the disco 3.9, the battery size that both vehicles left the factory with whatever the engine fitted in them.
The RR's from Mk2 (P38A) on, get progressively thirstier on the battery. The diesel takes more oomph petrol can manage. So many devices one or two draining will tip the balance and good luck finding which
Newer the worser - yes worser is made up
Im not sure anymore, too many replies today. Which do you think is worsererser?
Ok I’m aware of that even though I have never gone near a Diesel engine even the modern ones, petrol only for meOk but diesels usually have a larger capacity battery with more cranking amps. P38 petrol 72 amp P38 diesel 107 amp. It is pretty standard in the motor industry for diesel engine cars to have larger capacity batteries than petrol engine cars. Diesels are much harder to crank than petrol engines due to their much higher compression ratios. Also after the first couple of cranking RPM on a petrol engine there is little compression resistance. Compression resistance is always present on a diesel because the cylinders are always full of air.

Are these terms something to do with Brexit
Hard to pick out, some a gooderer than others and some are baderer.
