Could anyone tell me what the difference is between the Smart Chargers and the normal cheap chargers. Is it only the charging time?? or does it also give a longer run-time and a guaranteed full charge???
It is none of those really. The current can be higher or lower depending upon the charger so the charge time on a cheap charger CAN be a lot faster than a "smart" charger. The difference is simply an automatic shut-off on a smart charger (when full)

I guess you could call that a guaruntee.
