Im a dumb a$$, backwards battery connections
So i have a battery tender for my motorcycle, and I also use it on my XP.... somehow I plugged in the tender backwards.....and it charged for about 4 hours, I went to start the ski and nothing....checked battery and it has .75v....LMAO So my question is that if I drained the acid from the battery and refil with some new acid I have in a bottle would the battery take a new charge.... or is it just toast? DOhh

My battery tenders will not allow you to plug them in backwards... not to mention they have reverse polarity protection... was it a true battery tender product

yea true tender product, I had the factory pigtail connected to my bike and made a new one up for the ski, I know what you are talking about... but I had made my own pigtail with some aligator clips, and got the wires switched around. I was suprised the light on the wall wart was solid red like it was charging.... I guess it does not have reverse protection. I tested it again last night and it still works fine, charges like normal.
It is the basic Battery tender product, just has the wall wart (transformer) and a pigtail for the bike......oh well, I bet I screwed up the battery.. Lesson learned, if you have checked 3 times check some more

take your battery out of the ski hook a 12v light bulb to it and completly discharge the battery till its totaly dead, then hook up a standard charger 2-10 amp max (Not a trickle charger/ battery tinder)the correct polarity and re charge for 8 hours should correct the problem if the batery is any good, do not drain and refill the battery!

well now that you mention it, I did have a few miller lite's, maybe that is why I got the pigtails mixed up!

Good news! the battery has held a charge for the last 2 days, maybe it is not toast......50 more dollars to spend on more beer...
