Internal rechargeable batteries
Important: If you’re going to store your Neo for a month or longer,
charge it before you store it, and then again after you take it out of
storage to compensate for the batteries’ self discharge.
The AC adapter
A rechargeable Neo comes with an AC adapter for charging the
internal batteries. The specifications for the adapter are listed here:
• Class 2 transformer
• Input: AC 120V 60Hz 9W (US) or 230V 50Hz 11.5W (UK and

• Output: DC 7.5V 500 MA
You should always use the AC adapter supplied by AlphaSmart; don’t
use other types.

are never used lose their charge in about a month due to the self-
discharge effect.)
New NiMH batteries need to be “cycled”—also known as
“conditioned”—three to five times before they hold a full charge. This
means that, during the first three to five charge cycles, the batteries
