Harley Davidson Battery question

I recently replaced the battery in my 125cc scooter.

I bought an AGM off ebay for $60.

Interestingly, before it arrived, I found the correct lead acid battery, unopened at a thrift store for $6, so I bought that and am still using it.
The AGM is on the shelf.

The OEM battery in that Yamaha scooter lased from when I bought the 2012 model in 2014 until last year and almost 5,000 miles.
