 IF it is just a "plain jane" cureent limited charger(small power cube
 with no lights) no problem except the charging time will be longer.
 Determine the ratio between the two cell MAh rating and that is how
 much extra charging time required. Rembembering to NEVER leave the
 battery on charge for an extended time as they tend to overheat the
 batteries.
 IF it is a "Automatic" dual rate charger(typicaly with lights
 indicating Charging and Charged)there should be no problem as the
 Voltage curves are about the same and that is what they use to
 determine charge end point. And they are specificly designed for
 leaving the battery in the Charger.
