My 2012 Fit bought new still has the original battery 151R. Since it seemed sluggish last winter and because it is 7 years old, I think I would be wise to replace it before winter. If I could be sure that another 151R would give me as good a life as the original, I would just stick with that. But experience says aftermarkets won’t last that long. I have looked at quite a few posts talking about installing 51R which has more power but requires some significant modifications. Unless I missed it, I didn’t see any posts for installing a 51R in a 2012 and that there might be differences between different years. Has anyone put a 51R or other battery other than the original in a 2012 fit? Also, I know that the radio will be affected when the battery is disconnected. Is there anything else that I should know about?
Thanks for your help.

 

Search. Ppl have done it. You have to remove or modify the bracket. It will barely fit. The 2012 is same as other years of GE fit mechanically (at least in nearly all respects).
