Shoot, then I guess all of my small batteries are destroyed then. If that is the case, then why can I keep starting my powersports toys? I have a basic Yuasa battery in my Zx1100 Ninja - 4 years old (have had it go completely dead 3 times). I have a Murrays special in my Polaris Sport 400 - 3 Years Old (Has gone dead with a load on it twice from not disconnecting a snow plow lift). My Ds650 has a Walmart battery (Almost 2 years old) has gone completely dead twice. I also have a Walmart battery (barely bigger than a lantern battery) in my kids' Chinese 90 (Has gone dead once and is 8 months old).
I have charged all of these at a 10 amp rate. None of them have gotten more than warm. The 90 battery is the only one that I do not leave charging for an extended period of time.
Having a rather extensive background in remote control, it is typically accepted that 1C (1xCapacity) is a universally acceptable charge rate for almost any battery type (Even the tempermental Lithium Polymer batteries). Seeing how the typical capacity of a Battery for the DS650 is 13 Amp/Hours, it would be perfectly safe to charge it at 13 amps. The Outlander in question most likely has even a larger battery with greater capacity as it is a Utility Quad and therefore charging it at 10amps would pose absolutely no threat.
The reason for higher amperage and voltage charging is to break up any sulfation crystals that may have formed and turn them back into lead sulfate. If the crystals have not gotten too large, this process can indeed "bring back" a dead battery.
Well, after all is said and done it seems that my battery may be OK after all. I charged it over night for about 20 hours or so, on a 1 amp charger. Just now I took the charger off and the voltage was 13.17 volts. Will check it again in a few hours to see if it is still up there, and then I should do a load test of some sort.
I left my lights on my ATV on at camp over night the next morning the battery was stone dead, I gave it one pull of the pull start and let the motor idle for 10-15 min and the ATV's electric start was fine from then on.

Using your high amp charge rate, I see that all of your batteries keep going dead.
Thank-you for proving my point.

Boy have I really got it wrong...I always thought that charging a battery increased its electrical potential. Thanks for clearing that up for me.
I also must have it wrong that a lead-acid battery will self-discharge at a rate as high as 40% per month. There must also be no such thing as a parasitic load from various electrical components. My bad.
I bow to your supreme knowledge and experience on batteries and electrical theory (How could I not with all of the proof, clarification and facts that you have provided?).
Thanks for setting me straight.

It's 6 P.M. now, some 9 hours after I disconnected the 1 amp charger, and the battery has self-drained down from 13.17 volts to 12.79 - still enough to do the job. No load test yet, however.
FYI, here is a battery voltage & specific gravity (as measured by a hydrometer) to state of charge chart:
SOC= State of Charge
SG = Specific Gravity
V=Voltage

I would say that you are probably good to go. About 12.5-12.6 is resting voltage.
Well, the battery still shows about 12.79 volts, so I guess I dodged a bullet. Will load and recharge it a couple of times just to be sure, though. Thanks for the great help folks!
