What are your driving habits? Do you drive your car every day? Mostly long trips or just short trips around town? The stock battery in the BRZs (apparently the FRS/86 get a higher amp hour battery and aren’t as bad) are known to be pretty weak and not tolerate the car sitting for days or weeks at a time without being driven. This problem was only exacerbated with the change in battery charging logic in 17+ BRZs that means that the battery only gets a full ~14 charging volts when the electrical system thinks that it needs it.

So what I’m getting at is that I wouldn’t recommend modifying/changing anything on the car while it’s under warranty. If your car sits for days at a time or you normally only take short trips, keep the battery connected to a battery tender at home if possible.
