Replacing 488 Battery - Questions/Opinions

Took ownership of a 2018 488 in April and has been a ton of fun. The car 2 weeks back started to have the alarm go off after parking so I knew something was up but had to head out of the country. I am back today and the car will not start. The Ferrari trickle charger for an hour or so got the dash to light up at least and the battery voltage is showing 8.7V. I am going to get a wireless jump starter to get it going then drive it to my shop. When I opened the panel I was expecting to see a Ferrari OEM battery but it was instead an Interstate battery.

I am going to keep this car for the next 6 months and then move to a 812. I was going to buy a Braille battery to replace this one since I am not keeping the car forever. Is this a stupid idea when the Antigravity battery plus trickle charger/magnetic 4 pin adapter will be around $1300 vs a Braille (also adding a new CTEK charger plus adapter) will run $600?

Also for sanity check it seems the Braille B7548 is now B48-H6-L3?

This would be the correct battery? - https://www.cspracing.com/products/braille-battery-b48-h6-l3-endurance-series-agm-battery-12v-group-48-h6-l3-880-cca?gad_source=1&gad_campaignid=22810131539&gbraid=0AAAAACQ_uG_efq3dhMp7h1g3V33SHu1fW&gclid=Cj0KCQjwrJTGBhCbARIsANFBfgu2Bm1OWzacE9qw6CjaNZ_TroEfEBNEjCmRU1pwnuMNzP4n5FD3z18aAhHNEALw_wcB

Thanks for the input all.

these braises on sale aren't much more. They aren't better quality batteries?
