Huh..... I can't believe Zimmerman hasn't responded yet.....
For me..... Walmart / Sam's / O'rileys...keep the receipts and mark the batteries.
buy the 72 month battery and flip them every 2 years...
I have to keep at least 7 - 8 batteries happy for all my stuff that sits and is not driven daily...
keeping fresh batteries in these vehicles just makes good sense.
just catching up Frank! I'll give my .02
my original optima (labeled as a Gates) was made in 89...I traded it to Optima (Johnson controls) in 2010 for my Yellowtop even up, they paid shipping and all to do with the trade...I thought that was a great deal. My story of the battery also landed me a trip to the SEMA show in 2011.
I now have a Redtop in my 99-2500 p/u, and the Yellowtop is in the Maiden...both are on battery tenders for the most part when not in use.
I have documented my experience with both batteries in my Optima battery thread.
I have no brand loyalty to Optima, although I think Jim McIlvane is a great guy to talk with, and he has given advice to those who seek it.
I know there is a lot of good and bad experiences with Optimas that is why I started posting my status of my two batteries about once/twice a year.
I own an Interstate in my Vette, it sits in a heated garage stall all winter, and is on a battery tender as well...that battery has at least 5 years on it, no issues.
I own two different WalMart batteries, haven't had good luck with either one...the one in my JD lawn tractor I have to keep a tender on it, it won't keep enough charge in it to start after sitting in the cold for a week. It is 3 years old.
My Jeepster I put Duralast in it from Autozone, when I got the Redtop 3-2010, that battery has been good, and its on a battery tender when not in use for the most part.
Also ran across this tidbit...
Costco and Interstate are made by Johnson controls...along with many other brands:
Major customers include
WalMart, Sam’s Club,
Advance Auto Parts, AutoZone, Costco,
Sears, Interstate Battery System of America, Daimler, BMW, Ford, General Motors, Toyota, Volkswagen, Chery, SAIC
That said, I think its a crap shoot as well...although I do believe keeping anything that isn't used for more than a week on a maintenance charger is a good idea.
