Oh, ok... It doesn't sound like it's too messed up then.... I don't think you have to trash it... Of course, thats fast diagnosis from the confines of my kitchen at the moment! Lol!
I was asking about the type of charger to see about its capabilities... That charger should be fully capable of cycling the battery full balance charge and discharge. That will likely straighten it out although it may take more than one cycle to do it. You're more or less good to go at this point!
