Hi all, I have a 2016 Peugeot Boxer pvc and the cab battery is kaput. This forum has been so helpful in that I’ve got the battery out easily, but I’m stuck now , looking for a replacement. The old one is marked 105ah, do I need that or would a 90ah be ok? I’ve attached a photo of the old one...any recommendations gratefully accepted, I’ve confused myself with ah A and prices that seem to vary so much.
