Just picked up a Diehard Platinum Group 31 battery for $205 out the door, when you order online you get $62 off the regular price. This battery is comparable if not the same as an Odyssey PC2150. It has a 205 min reserve capacity and 1150 cold cranking amps. The Odyssey version sells for $373.

This is a great battery to run if you want added capacity without the work involved in doing a dual battery setup.

 

very interesting!
