Wii Controller Replacement Rechargeable Batteries for Wii Remote Control, White - 2 Pack

I got these to act as constant power sources for wiimotes used to make head mice.So far they are not tested under load, but my multimeter happily reported them to be 3.01 volts when plugged in ( gradually increasing, likely due to my multimeter and no load on them, or just a fluke ) and a bumpy drop to 2.8 volts when unplugged.In other words: Good news, these appear to work without posing a risk to your wiimote.They also appear to be decent quality.Cons:-Made in China-Packaging does not inspire confidence.

I ordered these to make my son's Wii experience less battery-expensive, and I made a good purchase. They don't last all super-long, but we don't use our Wii enough to really drain the batteries too quickly anyway, so no big whoop. I read a disturbing amount of reviews that people couldn't figure out how to use them; I find it disturbing because anybody with even a bare amount of technology-sense should be able to figure them out pretty easily. No manual came with them, but again, only a total tech moron couldn't figure out how to use them intuitively.I like that they charge via a USB port plugin; I just hook them up to my computer and they are charged super quick, with no need for a separate charging dock.I recommend these if you aren't an idiot and have a Wii.

These didn't last very long.

I bought these as a replacement to our old rechargeable batteries that weren't holding a charge any more. All the other rechargeable batteries I've seen require you to put the Wii controller into a cradle and I've had bad luck getting the contacts to line up properly. These are great because they plug in and I'm certain that they'll charge. I bought an inexpensive powered USB hub and run 4 of these at once. I really wish I had found these a long time ago.The only issue I've had is that I had to re-pair the Wii controller with the console and couldn't do it with these batteries. The plastic cover attached to the battery covers the pairing button on the controller and I can't reach the pairing button. I had to go find 2 AA batteries to complete the process, then put the rechargeable battery back in. Not a big deal and I've only had to do the procedure once, but would have been nice to give a hole to get access to the pairing button.

These do not have the metal strips that align with the charging tips of my wii. They come with a wall plug charger but you cannot tell when they're charged! The light never comes on and never goes off ... for WEEKS! Plus the charge seems to only last about an hour. I'm not impressed. In fact I'm pissed off.

Batteries work fine, but didn't work in the charger I already had. they have to be charged using a usb cable...one at a time.

Worked just great.Plug into the back of the Wii so no extra power requiredLimited run time I think; seem to require fair amount of charging; mostly play for a few hours and put it right back to charge (though I never tried to time them full to empty). Have to have the "skins/sleeves" off to use the charger.But for the price and saving batteries - well worth it.

Wow what a great replacement for something you would think to last for years. what a relief to find these devices at such a bargain to take a chance on. they do the job 100% better than what was replaced. I would recommend just not leaving plugged in all the time or they might get overcharged.
