2015年7月10日 · So it's time to replace the old battery in my B7610, and I'm looking at the battery specs and it specifies a 55B24L(S)-MF, which is indeed what is under the hood (by Yuasa). Do I have to look for this as an import, or is there any reason I couldn't just put in a 51C equivalent from my local tractor supply (much cheaper).
