damm didnt know about the costco one ,

my battery left me starnded last night walked 2 niles to wallmart bought one for $77 with a 3 year warranty

installed it and was on my way . that adventure took 2 hours out of my day

 

I also run the Diehard Platinum P5 .. main reason? Sears is open 7 days a week. Sears is just about everywhere. If there is a question on whether or not your battery is under warranty .. All Sears automotive centers are connected via their computers ..

jackjroadster .. changing a battery is one of the relatively easiest of DIY jobs.
