hey guys, so some of you may know from before (last year-ish) the batt in my car kept dieing when it got cold, well i replaced it with a Motomaster Eliminator the dry-cell ones like the optima. needless to say i go out last night and after noticing hard starts during the day while i was at work i decided to check it out, and it turned over once then died.

does anyone have any ideas what could be wrong? i highly doubt its the battery again but it does come with a 10yr warranty so i'll take it to canadian tire on friday (my day off) and go from there. but what else could be drawing power?

the only thing thats really changed and after it started happening was the addition of a capacitor for my sound system, but thats supposed to hold charge not drain it.

any ideas?
