What should I do if Im not going to use my HT for an extended period?
Just leave it plugged in, in a cool spot if possible. Leaving you Segway plugged in for a long period of time is believed to actually help “heal” the batteries to some degree. NiMH batteries will slowly discharge if left just sitting for an extended period of time. It is understood that some permanent damage can result in neglecting NiMH batteries. In the real world, several users have reported leaving their Segway unplugged for weeks or even months with no noticeable change in performance. But this is not recommended. It has been reported that after left plugged in for an extended period of time, a Segway may show slightly unexpected battery results on the following ride. This may manifest itself in slightly reduced range, or quicker than expected discharge. This phenomenon is reported to go away after a charge/discharge cycle.
