My redtop optima is failing on me now too, since the cold weather has come. I keep a battery tender on it but it doesn't like cranking over. Or I have some bad wiring going on again with my ignition switch. Jumpstarting it fixes the issue so it's probably the battery. Booo.
My experience with optimas has been either hit or miss. I had one that failed and one that lasted until I sold the car. Their service is horrible though, might as well not come with a warranty. I can't say I'd bother with them anymore.
FWIW, my Deka lasted a year of sporadic use during this swap and wouldn't hold past 10v. Replaced with an Optima yellow which has been drained to 5v a couple times and continues to bounce back when I throw a charger on it.
Mazda stopped using AGM batteries somewhere with the NB.
I know that the blue-label battery which the dealer parts counters in the US sell as an OEM-equivelant replacement are no longer AGM, however I wasn't aware that any NA or NB ever left Hiroshima with a flooded battery.
so who's had good luck exchanging an Optima, and where? mine is dead but i lost the receipt. advance auto parts where i bought it told me to get bent, even though it has a 04/07 manufacture date stamp. d00shes
Hmm what a coincidence! I've been having a problem with my yellow top this past few days. It dies every morning now!! Took it back to advance and I just passed the 1 year mark! So now I'm trying to find a replacement.
Why don't they make AGM or whatever the old OEM batteries are anymore? Mine has always worked even in sub-0 weather, and it's 16 years old. It has stopped working as well recently ever since an alignment tech discharged it with the brake light and then overcharged it with a charger, but nevertheless it still holds a charge to start the car.
In for another hassle-free battery that lasts 10+ years.
I have had several red tops and I can never, and I mean never, get them to recharge and last after they drain once... If I have them go down, it's usually just time to trade them in. That being said, the parts stores around town are really good about just looking at the date stamp and replacing them. I've taken two of them to the local O'ripoff and they replaced them with no questions asked...
