I purchased the Odyssey Extreme AGM Battery to replace the lower powered 540CCA Motorcraft battery that is failing (second battery) I will say it most likely is not the fault of the Motorcraft battery but the failure of the internal voltage regulator in the 2011 Ford Edge which has cause repeated drains on the battery and caused it to prematurely fail. Good news is I am taking the Motorcraft battery back for replacement and will have it on hand for a spare. This Odyssey battery has a 4 year full replacement warranty and 950 CCA's should start the Edge without a problem. It is also a Deep Cycle battery that can withstand 80 percent discharges over 400 cycles without damage, which is where the motorcraft battery was the weakest.
