If a repair shop (All Tune In my case) installs an Autozone Duralast battery and if fails, Autozone will NOT honor the warranty! All Tune & Lube @12490 NW Fwy Houston, TX installed a 36R-12 (7 Yr) battery on 11-14-2007. Failed 6-29-2010. 19 months service on 84 month battery. Run around starts with All Tune who tells me to go to Autozone and Autozone tells me to go to ***!! I was told by Autozone that your warranty is between you and the one who installed it. So beware if you have a Don'tLast battery installed!!
