I bought this battery brand new from eBay in February 2024 as I thought I need to replace my own battery. Turned out that rodents had chewed through my wire harnesses, so I didn't need the battery after all. However, in the process of troubleshooting, the battery became uncharged (due to the chewed out wire harnesses) and so I attempted to recharge it according to some Youtube videos, which instructed me to remove the top encasing of the battery to access the connections directly. I never successfully removed top encasing but broke a flange while attempting to do so.
