Hello,
maybe some of you know what are the specs (capacity and CCT) of the original battery that comes with the 1.9 mjet 96kW

Anyone?

There's the specs. The battery type is 027

I found that 60ah was ok, but the colder months were a hassle for slow cranking. I replaced it with a 64ah 640cca and works superb for better starting in the cold.

Ahh that's brilliant, Thanks for that
I thought 540amp was an upgraded battery, i'm surprised this is the normal, will give this a change end of the month

Replaced mine a few months ago with a 096 74Ah off a SAAB 9-3 TID starts on the button now, had to cut the front off the plastic tray to fit it as its slightly longer.
