Since that the weather has gotten cold here I've noticed that the OEM batteries that come in the accent suck. I have to plug my car in below -15 celcius so that my car will start in the morning. Its only when I'm at work I don't know if its going to start because I can't plug in my car. What would you guys suggest for a battery, something that has good cold cranking amps and that is easier on the engine when its cold. Also a battery I don't have to constantly plug in when the mercury hits below -0 celcius.
