How long should it take to charge my rechargeable batteries?

Using the 10-Station Battery Charger (Part #: RF25) it should take only three hours to fully charge your rechargeable batteries (Part #: RF16 or RF46). The green indicator lights on the charger should begin to turn green within two to three hours and should brighten as they reach full charge. They can also be left on overnight, as the charger goes into a trickle charge mode once the lights turn green.
