Does anyone have any input on which brand agm battery group size 48 or h6 would be the best to buy. I don't have a mini dealer near me and frankly probably cannot afford the OEM replacement. My options are Napa-legend, Autozone-Duralast, Rockauto-Bosch, Walmart-Optima, Advanced auto-Diehard, all of these are $300 or I have a local batterymart for $200.
