Anyone made the switch from the d3100s to these? Any big diff think my d310ps are taking a shit

No comparison BUT MINE ARE AMAZING.. especially the marine one

I switched and for the price and performance theyre better IMO

Being able to pick them up locally on sale is great.

I'm about to run 4 15 ethos. I have a singer alt 320 and two 5500s think 3 would be cool?

I got mine on sale for around 189.00

The platinum group 31?

I ran 4 3500's at .5 with 8 of them and a 320a alt and stayed in the mid 12's constantly.

I run an 240amp alt, and 3 Plat's in the rear on a 5500 at half ohm, never drop below 12.8, hell, i don't never drop below 13.6 when driving full tilt

Nope, you need one up front and atleast 4 of them in the rear.

I ran a two 5500's with a 370amp alt and had 8 batteries(4 group 31's and 4 group 34's) to stay in good range. 

OK cool thanks for the heads up guys

Try to put them on the charger

I did woke up they were at 12.6

After 24 hrs from being off the charger

I might unhook stuff and try again Before I buy new batts

At what voltage are you charging your batteries, also do you have a load tester? You can put a load on it and see if it drops to low voltage. Normally batteries just don't die, there is typically a reason if you keep your current setup you may just ruin another group of batteries.

Did everyone know that DieHard Platinum Batteries are made by Odyssey and Sold under Sears DieHard Platinum Logo!  Odyssey is one of the best if not the best agm battery out there.  Preferred and used by the military even.  I use an Odyssey Group 65 PC1750.  DieHards are just as good at a better price point : )

Take your batts to a auto parts chain and get them load tested!

They are similar to the odyssey 2150s although not as strong.

13v start load tested drop to 11.5 with a carbon load tester @ 400 amps for 30 secs

Rose back up to 12.8 but when I charge my batts they rest at 13 and are fine out the car soon as its hooked up I wake up to 12.6
