Yeah, for years my auto battery purchase has been from Sam's. About 5 years ago in FL visiting my wife's mother and I was just kicking it around while they were catching up....i visited Walmart they were selling an AGM battery (MAX something or other) at a third of the regular price (someone returned it).
Running that battery to this day with no starting problems...may have re- conditioned it a couple of times.
The Sam's battery is good! Sam's stands behind that Duracell product line, it's a little known service but Sam's will make a house visit to install the battery at no additional charge. I ve never taken advantage of the service. Three years ago the Duracell it went flaky on me and Sams replaced it for me at a decent pro-rated price...i found it acceptable. But it's now 3 years later and
( I believe) the cause of my car's periodic hard starts. Duracell is currently on the charger.
I've installed the O'Reilly Super Start in the Duracells place. Found the Super Start in a boneyard BMW...6 months old off the store's shelf. Now closely monitoring it's proformance especially seeing temperatures are dipping greatly around here.
Of course I might just need to replace the alternator which is at 230k miles...
Thanks for your much appreciated input!
