It's brand new, just installed it last night. Date code stamps make no sense to me.
For those with poor eyesight, I think the top code is J9GHB and the side stamp is 6J27BS2N
Battery was built October 2019 (J9) ,Not sure who actually made it,maybe someone else will chime in.
Pretty sure it's Johnson Controls, thanks for the date. I actually called the champion battery support number and they claimed J9 was November 2019, he said their letter codes are a month behind or something.
