Sorry to hear about your battery troubles, but I thought you would like to know I really like your animated icon.

This is a battery setting on my work bench, not connected to anything. I had taken it to an authorized Interstate Warranty Dealer in my area. He in turn put it on a charge system and analyzed it with a piece of equipment provided by Interstate. I have done nothing but let it sit a couple of weeks at this point.

Do you by chance have an electric jack hooked up?  On my last trailer that had on it pulled a little bit off my battery even when it shut off.

Just make sure they give you a deep cycle and not starting battery.

As a follow up...
I never received a call back from Interstate so contacted them again today myself. I was connected with the local Interstate Battery Store which is supposed to be company owned and not a dealer. I was told that they will re-evaluate the battery and offer me an upgrade for $15.00 since the battery I have isn't carried in the area. Hope this turns out to be worth the hassle and run-around.

I have a call into Interstate and am awaiting one of their customer  service specialist to get back with me, had hoped that would all be in the same day. I also mentioned that this forum was how I discovered another customer with the same issue. We'll see what happens...

I'll repeat my other post above - even w/o a battery tester the voltages you reported leave no doubt at all that the battery is trash and should be replaced.  If your dealer argues that a 6 volt reading is fine he knows absolutely nothing about lead acid batteries.

I agree completely but the dealer seemed to be afraid of going against anything his battery machine didn't tell him. Essentially, at the time I picked it up from them it was fully charged and I think it said 440 CCA and stated the battery was equivelent to a 16 month old battery (it was only 12 mos. old). Anyways, he wasn't going to give me a new battery at a prorated price period.. I guess I could try calling the corporate office but I have limited time to mess with it all.Angry
If I end up buying a new battery I'm thinking hard about buying 2 - 6 volt golf cart batteries, that looks like a better way to go given their high capacity. I've done a little shopping around on them and they're not cheap by any means.

It might be equal to a 16 month old battery....it's hard to tell what kind of shape it was in when you got it (perhaps it sat on the shelf for several months self-discharging, sufating, etc.?).  However, the attitude seems to be that you are guilty until proven innocent.  Though I'm certainly no expert, it would seem that even a 16 month old battery would perform better than what you are getting.
 
A number of folks favor the golf cart batteries.  Since you're starting from scratch anyway....certainly worthy of consideration.

DogHouse, yes and no on the 6 volt batteries.  You need to look at the total watts available - that number is the same no matter the volts or amps, since volts times amps equals watts.

Your average deep cycle battery is around 110 amps @ 12 volts.  Paralleling them you get 220 amps at 12 volts, or 2640 watts.

Your average golf cart deep cycle battery is around 220 amps @ 6 volts.  Putting them in series you get... 220 amps @ 12 volts, or 2640 watts.

Having said that, there are 2 advantages to using the golf cart batteries.  First, you can run into issues with the 2 batteries in parallel, where one can take on more of the load and also take on more of a charge, eventually causing one to fail before the other.  Its physically impossible to have this problem with the 2 batteries in series.  Another advantage to the golf cart batteries is the internal cells are twice as big as the cells in the 12 volt batteries.  That makes them more resilient, able to last longer and/or take more abuse.

I have seen reports that Costco has 220 amp golf cart batteries for around $75, but I haven't been to Costco lately to confirm.
