DieHard Platinum 31M DEAD

[TomH]

I understand what the lady from Odyssey said but I don't believe her.
A snapshot of a great battery article:

Basically there are two types of lead acid batteries (along with 3 sub categories); The two main types are Starting (cranking), and Deep Cycle (marine/golf cart). The starting battery (SLI starting lights ignition) is designed to deliver quick bursts of energy (such as starting engines) and therefore has a greater plate count. The plates are thinner and have somewhat different material composition. The deep cycle battery has less instant energy, but greater long-term energy delivery. Deep cycle batteries have thicker plates and can survive a number of discharge cycles. Starting batteries should not be used for deep cycle applications because the thinner plates are more prone to warping and pitting when discharged. The so-called Dual Purpose Battery is a compromise between the two types of batteries, though it is better to be more specific if possible.

I think what you are missing here is all Platinum batteries are deep cycle so it's likely there is no difference between the auto and marine versions, other than the second set of terminals.

When I bought mine, I chose a Group 65 strictly because it was the of the warranty. At the time the marine batteries were 3 year replacement and the auto batteries were 4 years replacement/100 months pro-rated. Mine died after about two years and was replaced.

Maybe I'm isunderstanding what your saying but I never recommended another 'Platinum' battery. I recommended a Sears DieHard AGM Advanced Gold, which is not a marine battery.

You said you didn't believe the lady at Odyssey. I assumed you didn't believe the 31 and 31M were the same.

Hello,

Yes, the only difference between any of the PC2150 ODYSSEY series batteries is labeling and terminal configuration. They all perform the same and are manufactured using the same TPPL AGM technology.

Oh, I see what your saying now. If they are putting the same lead plates in their marine(deep cycle) as they are in their auto batteries then, like someone else said, it's just so they can rip you off on warranty. But I don't see a 31 non-marine Platinum DH battery. If they are using the auto plates in a marine battery they wouldn't last long @ all as a deep cycle/marine battery. If they are using the deep cycle/marine plates in an auto battery then they will last longer than vice-versa but it's far from optimal.

If it were as plain as the charge currents being too high, you'd think we could get around that with some electrical engineering.

I will toss my 2 cents in as one of my Diehard Platinum's died this weekend.

It was fine 3 weeks ago, the FJ40 sat for maybe 2 weeks.....dead battery, put on NOCO charger, drove the 40 for a few days, back on charger for 2 days, parked it, dead in another 2 days! I can now put it on the NOCO and within 30 mins it says its fully charged.....but its not.

date on the battery is 9/11, so its close to 3 years old, was in my FJ40, I went to Costco, got a group 27 deep cycle and put it in.

I have 3 other Costco/Kirkland deep cycles, never an issue from them. the one in my 45LV is the one I put in when I bought it 8-9 years ago. Others are close to that old. One sat for 5 years, sure it was dead, but it took a charge just fine, fires up the 45 pickup everytime.

in my 2000 100 series, I have a Odyssey 1700, its over 9 years old!....never an problem, it ran a fridge for years. Sure i have killed it before but its always came back fine.

in my 40 I use to have a pair of small Odyssey 650's(I think) I used them as I could put 2 in a overlarged tray, 1 of those died after 7 years, replaced it, other died a year latter(so 7-8 years) I replaced both of those with a single DHP 31(PM2).....the one that died this weekend. (the charging system is stock and working fine)

my 60 has one DHP 31 and an older(maybe 5 years old) Excide AGM...they have not given my any issues.....yet, think the DHP is 3-4 years old. I have a 200 amp Mean Green alt in the 60

I use either a Battery Tender or NOCO to get them charged

in short, the real Odyssey's seem to be a much better battery than the DHP, but a good ole Costco Kirkland battery is almost(or as) as good and a heck of allot less money. So the choice is to pay more or pay less.

the DHP I replaced today lasted the shortest of any battery I think I have ever owned, I think even my worst Optima lasted longer

I will take my dead DHP back to Sears, hopefully(no receipt) they will give me a new one, guess I will put it the 60. But I am damn sure I wont every pay for a DHP again.

I run dual Odyssey batteries with hell roaring isolator switch in my ride and have had them for a few years now with no issues- besides wife or son leaving the headlights on and forgetting to turn them off and running 1 battery completely down a few times- AGM battery charger restores downed battery in no time. I know that my battereries manufacturer (EnerSys Energy Products Inc) is the manufacturer for Sears Diehard batteries- just surprises me to hear people having issues like that. Of course, my batteries are the smaller 1200MJTs sitting side by side in single battery tray. and there isnt a diehard made in that size...

Can you give some more info/photos of your twin battery install?
Thanks

I've had the DieHard for a while now and it's fine. I've run all different kinds of batteries: Costco Kirkland, Autozone, heavy duty.
They all died quickly.

I don't daily drive my truck, it sits for long periods so the addition of a battery tender is the biggest battery saver.
The DHP is the longest lasting battery I've had in the last 5 yrs, and I think it's because of the Battery Tender Jr

On the surface, I could say the DHP is great and the other batteries suck but I honestly think it's how it's stored.
I bet all of them would last a decent interval with the trickle charger.
