I had been using my Wii fit without any problems until I got (1) a rechargeable battery pack and (2) Wii fit plus. Since then, I don't get very far until the blue light on the balance board starts flashing and the message appears that connection with the board has been lost and to turn it on again. I have tried re-synching the board, ... nothing works. I checked whether or not the board was functioning properly, and it's okay. It works with normal batteries

If a Double-A battery insert is present, then take out your rechargeable and insert 2 Double-A batteries. Then, start up the remote and point at the screen (Making sure sensor block is in range and exposed) so the remote can re-calibrate. Once done remove the batteries, if you'd like, and re-insert the rechargeable battery pack. IF this fails, simply remove and re-insert the rechargeable battery pack. Shut down the Wii manually at the home unit, and then start it back up using the Wii remote.

rechargeable batteries are definitely a better bet. I have used many Wii battery packs and chargers, none seem to last very long.

Seems the rechargable battery pack was the problem. Switched to normal AA batteries and it worked straight off.

JUST CHARGE THE CONTROLERS

#1 rule for batteries do not overcharge/overvolt, dispose of in fire or throw at your cat unless you like fireworks.

you will need new batteries for your wii, i have a couple of rechargeable wii battery packs that i bought from EB Games they work fine, they hold charge, and they save batteries, my fave part is where you buy 3-4 of them and you have two charging while you use the other two.

also a small tip, the nintendo wii is very anal about voltages, but a pocket flashlight isn't. you can take batteries that refuse to work in your wii and put them in your flashlight.

Guest: Rechargable batteries are only 1.2 V each. You should get up to 4.8 V.

I highly suggest running your Wii Fit on nothing other than Alkaline batteries. I've had my Wii Fit for over 3 months and still use the original batteries.

If you feel like you need rechargables, that's fine, but I recommend a quality set of regular AA rechargable batteries that comes with a quick charger (IE: 1-hour). Stick to the same brand of batteries and buy enough for each Wii-Mote, Wireless Guitar, Wii Fit Balance Board, etc.

Amy - Keep in mind that your Wii Fit balance board will ONLY turn on when your program (ie: Wii Fit) is loaded and ready to go. Since the balance board takes up one of the four available Wii-Mote channels, make sure all but one Wii-Mote is turned off before starting Wii-Fit.

Make sure that whatever game you are playing (ie: Wii Fit) is fully loaded before pressing the power button.

If the light continues to go off, you may need to re-sync your Wii Fit balance board to the console. To do this, load Wii Fit, and when the program is running, press the red button inside the battery cover. Immediately press the same type of red button inside the panel on the Wii located between the eject and reset buttons (on the face).

If these steps don't work, try fresh new alkaline batteries and repeat.

Note that there have been lots of complaints using rechargable batteries. I've had the same alkalines in my unit for 3 months now. If insistent on using rechargables, I suggest buying several of the same battery and a quick (15 minute or 1 hr) charger as opposed to ANY after-market recharging product. It will be cheaper and more reliable.

Good luck!

make sure the battery charger is connected, and that the port connections are tight, other than that I would say you have a faulty charger.

If you remove the rechargable battery pack and put regular batteries back in, are you still having the same problem? If so, I would recommend returning the rechargable unit and replacing it.

For what it is worth, I've been using my Wii Fit board for nearly a month on 4 alkaline batteries and have not had any problems.

I recommend rechargeable NiMH batteries with a 15-minute quick charger. Always have four more batteries than you need in your machine, ie: if you have a Wii Fit, a Nyko Wireless Sensor Bar, and two Wiimotes, then you should have 16 batteries total (4 + 4 + 2 + 2 + 4 spare).

Good luck!

Have you tried regular batteries, the UK model takes 4 AA batteries or is the US model different? Cheap third party battery packs made in China are rubbish and never work for long if at all.
