When I bought my Accord back in January it had a 62Ah RAC battery which didn't even fit on the tray properly, and was held in place with a Ford battery clamp lol I replaced it with a Bosch S4 021 battery (type 158 I think it is) which is 44Ah and has a CCA rating of 330 amps. Looking on the Lings Honda website and Google Images, the OEM battery (p/n 31500-ST3-111HE) appears to be a 48Ah battery with a CCA rating of 420 amps. Assuming I make sure my battery is always charged up, is it OK to stick with it or should I sell it/keep it as a spare and buy the OEM one? The only reason I got the Bosch is because I've always bought them for other cars and have never had issues with them. The Bosch battery application guide shows that the one I bought is the right (and only) battery for my 2.4.
