Won't start

A new battery should be 12.5-12.8. A little older probably 12.0. Yours, at 10.3 after a charge, has served it's life. I've had good service from Deka brand but Interstate is also good.

It was on a smart charger all the time. You lose your bet

Smart charger can mean a lot of things. If not something similar to a CTEK 4.3 with a reconditioning cycle, just charging then switching to a trickle charge isn't something most would call any kind of maintenance. Anyway....those chargers are incredible and running that cycle once per year will significantly extend a battery's life all else being equal. Expensive for what they are, but do pay for themselves...

Yes. A 12.6 volt 6 cell battery has about 2.1 volts/cell when charged. You're missing a cell, that is a cell is shorted, probably from building up sulpher deposits.
You can find out which cell it is with a battery specific gravity tester. Charged cells should have a specific gravity of about 1.265, discharged, or not fully charged cells will be less. Then again, it doesn't really matter what cell is bad if the battery is useless unless you can de-sulphate it.

I would recommend Interstate batteries.

The Genius is similar to the CTEK and has a recondition mode too. Have you tried running a couple cycles of that? Mine will allow a cycle to complete and then run another full recondition cycle if you want without need to discharge some in between the two.

My CTEK has saved some batteries I was sure were toast.

Yes Murph, Get another Interstate from fresh stock from a local dealer. You won't have to worry about a dead battery in dead of winter. Forget reconditioning your dead one, its toast. The price of a good battery that lasts 7 years over that time, is less than an expensive coffee and cruller once/year. Why waste time, electricity, and aggravation on a dead horse?

Our son bought a set of blemished Interstates about 3 years ago for his IH 686, two 12 volts. It still zips it over like the day he put them in. He paid $35. a piece for them. Personally I couldn't see anything wrong with them cosmetically. I think they both had a black X on them for some reason, I guess so they couldn't be sold as first quality.

They're marked as seconds and sold at reduced prices. Good as new, and same warranty, IIRC. I'm a former Interstate dealer and get a reduced price on all Interstate items because of having been a retail dealer years ago. I too have bought their seconds; they are just as good, but even less money. Yeah!
