HDI Battery

[powerandtorque]

I'm well aware of the finer points of batteries, cold engines and the weather. I'm also well aware that there's cheaper sources that ECP - as I said, that was purely a comparison between different sizes of the same brand of battery from the same supplier.

You'll also note I wasn't suggesting buying an 065 battery, merely pointing out that in the real world a few year old one is more than capable of starting an HDi even in the depths of winter (certainly no issue down to -10). That's hardly a surprise of course, as Peugeot will have specced the recommended battery for a worse case scenario and the sorts of temperatures that we just don't see in this country.

There's no harm in putting in a larger battery with higher CCA rating of course, but in my opinion, there's no tangible real world benefit in doing so.

apparently just a relabelled bosch silver they are, last Varta lasted me 8 years so cant complain at that haha.

If that's true I hope that they've improved over Bosch Silver's of a few years back which were a disaster - I had three fail in well under a year, and I'm far from the only one that had issues with them (ironically in light of Big_K's post, that was a battery that was slightly over-specced for the car it was in)
