[quote name='hack']Well the battery life on Wii Remote is really iffy. I mean the remote has rumble, and of course special sensors, not to mention it's very own speaker, and its wireless. The manual even says that it uses additional battery power when the Wii Remote is used as a pointing device.
The Wii Remote eats normal batteries and spits them out faster than you can say Twilight Princess. Which is why its literally suicide to go with non-rechargeables.
I always say buy 2 or 4 extra batteries. That way when your first set dies, you simply grab an extra two that have already been charged and pop them into the remote, recharge the dead ones, lather, rinse, and repeat.[/quote]
My original Panasonic batteries that were included with the Wii lasted over 20 hours of Zelda time, not to mention quite a few Wii Sports marathons.
I think mine lasted so long b/c I actually turned the Wiimote speaker off. I usually play Zelda at night when my daughter is sleeping, and no matter how low the Wiimote speaker volume is set, some sounds still sound like they are blasting (collecting rupees for example) so I just turned it off.
I have rechargablebles for my digital camera, I just need to go out and get some more to use with the Wii.
