I need to replace the battery on my BMW and was about to buy a 16CL-B from Walmart http://www.walmart.ca/en/ip/10309509-everstart-battery-es16clb/6000016955307 I checked Amazon and found this http://www.amazon.ca/gp/product/B00BMUJ5...d=AMQ1Z843UINJG The $40 price cannot be beat and, since UPS Battery Center is a Toronto company, I am going to check on Monday to see if it can be picked up and thus avoid shipping fees. PowerSonic is a California based company http://www.power-sonic.com/ The battery seems Chinese made though. What was really surprising to me is that the battery is an AGM. I thought AGMs typically cost twice as much as flooded lead acids. Any opinions on PowerSonic batteries?
