AGM replacement batt recommendations?

Post by RetroBiker » Wed Jun 18, 2025 5:49 pm

I've been online searching for an AGM replacement battery for my '67 CL77, and found that physical sizes vary greatly. Batteries Plus sold me one that would not fit, so I'm hopeful one of you kind folks can provide a vendor and part number of a battery that will fit my bike. High Tech Battery Solutions says their Origin Battery is a direct replacement, but I've not heard of them and was curious if any of you had?
I've spent 2 years and too much money getting my project to this point, so I just don't want to go back to a flooded battery that might destroy my brand new paint job. Any AGM batteries known to fit this model would be greatly appreciated.
Thanks so much for your help!

Hey Guys,
I am happy to report that the MB5U MotoBatt 12V battery fits in my CL77 perfectly and is putting out 12.5 V. If you're looking for an AGM battery for this bike, definitely considered this battery as an option although it is rather expensive. We'll see how it holds up over time even though I plan to use a battery tender.
