just because you had a bad experience with a kinetic battery, or heard bad things about them doesnt make them bad batteries, i have not had a single problem with my HC2000 and i love it. like with anything you buy there is a chance it will not work or possibly go bad on you.
I'm personally running an hc2400 and I have a friend running a kr3112 both are aswome batteries and as I've read there are no HUGE differences but do some reading on google you may find something out i don't know. Hc2400 has worked aswome for me though.
kinetic batts are top of the line but when going that big you can get a similar batt for a lot cheaper ex. c&d, sprinter and so on trust me you can save some coin and get the same results. check the classifieds for them
