Upgrading 12v Battery - 2019 Corolla Hybrid

[Draebor]

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'm no expert when it comes to batteries, but I'd ask around a few other sound shops for the correct size. I would also assume if one is installing a powerhouse system, then the alternator may also need to be upgraded too. An auto electrician would be the best person to ask.

As for calcium batteries, I can attest to their outstanding performance and longevity. I am still running an Excide Calcium battery in my E36 M3, which is hardly driven, is on a battery tender and the car still fires up 10 years later. It is still good after 10 years ! I am still in disbelief myself, but when it finally dies, I will definitely be seeking another one.
