The petrol models take about 200A to start when warm. Maybe 250 for the V8 and diesel. There is no need for more than 500-600 the rest is overkill. Important is the build quality so in five years it still has 500cca out of the 800.

My 3.0D (M57N) diesel has a DNIN85LMF, which is only rated at 780CCA - works fine. This DIN85LMF battery was fitted by a previous owner so when it needs replacing I'll go back to the recommended DIN88LMF, which vary a bit on the CCA rating depending on the brand etc. (but are usually 810CCA or greater, although I've seen cheap brands of DIN88LMF batteries rated at only 780CCA ... ).

Good points. thanks. I have been out for a short drive and the car has been resting for two hours. I went out and did a #9 obc test - turning the ignition switch to pos 2. The lights turn on due to dark cloudy rainy day and the air con on. The reading is 11.6V. I am assuming this means the batter is towards the end of its charge life unless there is another issue. I will open the cargo bay floor and have a look to see for a date code tommorrow.

Under 12 before starting not great. Yes sounds end of life to me unless you have a ground problem or such. Get a reading at the battery

Heck of a load on the battery for this test though - ignition on, engine off but headlights and accessories running is probably 20-30 amp load... Even a good battery could show under 12v on the BC under these conditions (due to the battery's own internal resistance and the various losses in the BC measuring circuits).

True that might be an absolutely normal value

I have officially 'outsourced' my batteries to AAA. Their battery service came to my house and installed the thing for $190. they got there in 45 min on a Saturday.

It's totally not my M.O. to not research it and figure out the absolute top performing, best bang for the buck etc, but the battery I replaced was also a AAA battery from an emergency install in 2012. it lasted 7 years. no issues whatsoever.

I know not everyone is a AAA member but if you are, a lot of folks don't know about their battery service, which in my n=1 experience, has been very good.

the new battery came with the little plastic elbow for the new vent connecting it was super easy.

Was the battery liquid or AGM?
