Engine/Starter Battery

[Lazyboy]

Looks like I need a new starter battery.
What do knowledgeable funsters advise on the best product to purchase?
It is a stop/start battery.
I would like the greatest capacity in terms of Ah and cranking available.

I would simply replace like for like and turn of the stop/start function.....mine is on by default but I turn off every time I turn the key.
I can't see any real gain in a bigger starter battery
