Odyssey vs. Diehard Platinum

Couldn't find the email so I went ahead and gave the person a call I talked to before. Didn't get her, so left a message asking about side terminal connections and high drain applications. Will post soon as I hear back.

ok, this is the reply I got

Ok, good to know.

And another reason to buy Odyssey/Platinum Diehards vs Optimas. I'm no longer a fan of Optimas having lost two in the last two years.

Even if I were looking for an Optima type battery, I'd go with the Exide instead, which is what I did in 2001. When they finally needed replacing I went with the Platinum though. If not the Platinum I'd have stuck with the Exide as I had good service with them.

That a wet battery not AGM, right ?

Thats funny...all of them and I mean all of them (optima,exide,DH) are all priced at 189...so the price doesn't seem to come into play here..

Well, given the destruction of the US dollar, anything commodity related will probably continue to increase in price for the foreseeable future.

This kind of sucks, because I really want the DieHard Platinum, but my Optima Yellowtop auxillary battery refuses to kick the bucket. I guess I bought it before Optima quality went to krud.

But, what if I buy the DH Platinum and just shelf it until my Optima dies...maybe 1-2 years? Is there any issues with that as far as the battery performance in the long term? (short term draining while it's sitting on the shelf is not an issue since this would not be my starting battery, and would re-charge once I installed it and drove 'round a bit)

Any thoughts?

Batteries have shelf lives. Do not buy one before you need one. You wont be saving money with a battery that has lost a portion of it's capacity just sitting undercharged. Perhaps if you were to keep it on a float charger, but over 2 years that could add 20 bucks to your electric bill.

AGM's do not self discharge very much compared to Flooded, but they will still sulfate and lose capacity.

My buddy has a 8 year old optima still in the plastic, and refused to believe it was no good anymore. " It's still new!!, never used!!" he kept muttering.

5.42 volts does not lie. We got it charged up with the parallel battery method. Put it on a desulphating AGM charger/ conditioner for a week, and 6 hours after it was removed from the charger. 11.7 volts. 24 hours 9.7 volts. 48 hours 6.7 volts.

Thanks, wrcsixeight.
But I gotta wonder...surely when I go to a store and pick up a battery...there's a good chance it's been sitting there a while. So I wonder, what then is a good rule of thumb for max "buy before use" time -- 3 mos? 6 mos? 8 mos?

Bummer, spent the last two hours at Sears.
No Platinum or Gold Diehard will fit my Blue Torch battery tray.

He threw a bunch of different batteries at it, and no go.
The tray would have to be modified quite a bit.

Going to suck up to Optima again and get a Yellowtop, despite hearing how bad they are and my own experience with mine going to 10.5 volts a year later.
Maybe I will get lucky this time.

He also said I should not use a Platinum Diehard for the starting battery when the Toyota one dies later, but I see many do use a P-1 or a P-5 with no problems.
