Yea I would not cut off the wires either. Like kirrbby says that is either the original battery or it was originally bought from a Honda dealer
All my bikes have 6V sealed maintenance free batteries now. For the $15 bucks they cost, it's a no brainer. I hate wet lead acid batteries as we all know they leak and require constant baby sitting. But, I did cosmetically restore an original green 6v battery for show purposes in my one K1 CT70. It will likely never be ridden again just given my life long ownership and attachment to it. I have another bike that is my rider, and not afraid to get it dirty. I simply wanted an original battery to display in the bike so I tackled replacing the cut off wires inside the epoxy filled terminal holes. It was quite easy once I removed the original epoxy and unsoldered the wires. Then I found some blue and red wires, placed clear shrink tube over them where they enter the battery case, just like the originals had. Then soldered to the terminals of the battery. Then filled the square holes back in with black 2 part epoxy/plastic weld. I then had to wet sand and polish it up a little bit to make it look better. I'm quite happy with it and it looks perfect sitting in there. Some might say it's stupid or a waste of time, but I took it as a challenge. And if that's not visually appealing enough for some, I do have a NOS original never activated 6v Yuasa battery in the original box that I can show with the bike. So yes, the original batteries do have some worth to whack-jobs like me! 😂I would not even use a wet battery after having a gel, but I learned not to throw any original part out. A Z is different though since they are so obvious. Took me a long time to find the correct colored Yuasa even though it does not have the Honda wing. The wrong battery and number plate bracket really jump out but did not seem to affect the auction price a couple of years ago.
