   Perhaps what's confusing are the words "trickle charge." You don't   
   "trickle charge" LiIon cells in the sense that most people think of   
   trickle charging. A charger limited to 220 ma at 4.2 volts max is a   
   constant voltage current limited charger, more commonly called a   
   "float charger."   
      
   Forget "trickle charger" and just pay attention to the description NP   
   gave of its electrical characteristics.
