Battery installed, all working as intended so far. now to wait on the sub install, car audio joint booked out till mid feb!

I'm looking at putting a decent sub and amp into my 2019 corolla hybrid hatch. The car sound guys im dealing with have recommended to upgrade the 12v battery in the corolla before getting the sub installed as the stock battery probably wont run the amp and sub decently. Anything to look out for when swapping out to a higher CCA battery for the hybrids?? Been looking at a Delkor 500CCA Calcium battery as a possible upgrade for it.

I have a tarago, 1987 model with a dead battery. have looked high and low for the battery but cant find it- its not under the seat or in the compartments behind the drivers seat. help!
