I was wondering the same thing
I think it's just a really trustworthy brand but I truly have no idea.
Nickel Metal Hydride batteries last longer from my experience.
I suppose one could use rechargeable alkaline batteries too which is safe for other Nintendo accessories/handhelds. I think Nintendo opted on the NIMH batteries because of the high power consumption. Also if you completely drain a NIMH battery there is no memory effect issues. Do that with a rechargeable alkaline and it may not retake a charge or will severely damage the batteries ability to store a full charge for any length of time.
Yes, the NIMH batteries will give you the most for your money. Plus it's best to play it safe since that is what Nintendo says to use. The Rayovac NIMH Hybrid series from what I hear are the best. They may be hard to find in the stores since they just came out. They can be purchased off of Ebay though. I have always used Rayovac rechargeables and feel that they outperform their Duracell and Energizer counterparts.
Yea when i first got it it came with some batteries that lasted quite a while, id say 18-24 hours. now i am borrowing the rechargable batteries from my digital camera lol,
How would you check the battery level?
I don't own a Wii yet so any guess is speculation. I'm thinking the green light on the bottom of the Wiimote turns red like my Gameboy Advance SP does when the battery is running low. If anyone knows for sure please chime in since I'd like to know the definative answer to this as well.
Hit the home key (in between the plus and minus key) anywhere and on the bottom of the screen is the battery level
