I recently found a great deal on a 12.5 for my 2 year old. The guy I bought the bike off of said the batteries where shot, had been sitting in the bike for months untouched. He refunded me 100 bucks to buy new batteries, which I ordered. I charged the old batteries on a battery tender and they took a charge up to 12.38, and 12.56. My question is recharging these like this will they hold that charge? How much of the original integrity is lost?
