Bad battery or bad alternator? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

You all people with your batteries dying have me scared. I have a 2013 FR-S, its still rocking the OEM battery. I guess all of the extra stuff the BRZ comes with (and extra things people put on, like cameras and what not) really drain the literal life out of it. I have nothing on my car, basic radio, no other fancy things (scion after all, no options).

Climate also is a factor, the heat kills batteries after a while.

Yep, and:

Red Top. Can't go wrong IMO

just left the dealership, got a brand new battery for free, I was told that the tester indicated that my battery was faulty. Couldn't be happier
