Always use the battery pack supplied as an accessory or an
equivalent battery pack specified in the User’s Manual. Other
battery packs have different voltage and terminal polarities.
Use of non-conforming battery packs could generate smoke or
cause fire or rupture, possibly resulting in serious injury.
After repeated use, the batteries will finally lose their ability
to hold a charge and you will need to replace them. Under
certain applicable laws and regulations, it may be illegal to
dispose of old batteries by placing them in the trash.
Please be kind to our shared environment. Check with your
local government authority for details regarding where to
recycle old batteries or how to dispose of them properly. If
you cannot find the information you need elsewhere, call
Toshiba at: (800) 457-7777.
