AAA batteries

Hint: In high usage environments it is a good idea to have a spare
battery pack. Alternating the spare battery pack between charges will
prolong battery life.
You can also use an optional AAA battery holder with your
portable. Insert the batteries into the battery holder.
Note: Commercially available AAA NiCd batteries cannot be
charged in the C3050 HiCapacity Charger.
