I’ve been blissfully ignoring this system but now Mums 2017 Subaru Forrester had a flat battery. Seems like a replacement is likely but it’s currently on charge and I’ll run a couple of checks first.

Preliminary discussions with my battery supplier has suggested that these sort of vehicles can need some reprogramming after a change. Is this to reset any adaptive battery management? Is it to specify the exact battery specs in which case if it is an exact replacement will this need doing? Is it something super annoying like an individual serial number of an imbedded chip?

Can anyone offer some insight.
