jrr102486, you can drain them by hooking up to a 12 volt car bulb.........sset it outside away from anything and let the bulb drain it down to zero.

Crash you need to be more specific which pack of ours do you want to compare with which pack from kokam. I will tell you from the start ours are cheaper and we offer the 3yr/300 cycle warranty not to mention top notch customer service if a problem should arise.
