Battery - SCOLA TEACH
One AA battery is required for SCOLA TEACH. The re-
chargeable battery included is a nickel-metal-hydride
(NiMH) type battery. It is environmentally friendly and
does not contain heavy metals. The contact surface at
the negative pole ensures that only this type of battery
can be charged in SCOLA TEACH.
The lifetime of the battery depends on the number of
times it is charged. If the battery is charged daily, we
recommend changing the battery once a year to ensure
optimum operating time.
Other battery types can also be used, but cannot be
recharged.
