replace small scooter battery with car battery??

[username]

I was wondering if anyone has ever done this, or know of anyone that has done this. The reason I'm wanting to put a car battery in mine is because I have a charging issue that I cannot for the life of me figure out. So, I charge the battery to full and ride until it either cuts off on me, or when I think it's about to I go home. No disrespect, but I'd rather not talk about fixing the problem or anything on this thread. I just wanna know if anyone has done it, could it screw up anything, things of that nature. I have plenty of room under my seat, and already have a way to mount it securely. Thanks in advance!
