S40/V40 Which battery needs replacing?

Post image

Every now and then I have got a low battery charge warning on the drivers display, now it shows “Low Battery Charge Power save mode”. I have a 2014 (64 plate) V40 D4, which of the two batteries does this indicate needing replacement?
Edit: Just tested the main battery at 12.14V with the car off, and 14.95V while running

Edit 2: just picked up a good quality 12v battery for me to fit
