I've owned my 2005 SRT roadster since 10/07 and it still has the original equipment battery. I haven't had any problems, but as a preventative measure, I am thinking it should be replaced. MY SRT is only used between April and Oct. and is kept in heated storage, and started and run for 20 minutes every few weeks. Rather than the battery failing at an inopportune time, I choose to replace it now. I've done some checking for replacements. The most economical find was at O'reillys part#48-72 for $94.00 with core trade. Others were NAPA BAT 9848 at $210.00, and Interstate MTP H6 at $163.95. The Walmart Everstart 48-3 at $62.00 is no longer available. Anyone else found anything better?
