2015 Cadillac ATS - What are my battery options?

The short life of the battery in my 2015 ATS coupe. I am 0n my 2nd battery battery after six months of use. Is there a lead acid battery I can replace this gell battery with ??

I do not think the batteries are your problem. If I am remembering correctly, I believe caddy’s of your age have had a lot of problems with a parasitic draw draining the batteries.
