Can you overcharge rechargeable batteries. The battery pack says it's 4.8 volts, I checked with my meter, and it reads 5.6 volts. When I put it in radio, it just beeps. None of the keys will work.

take it back for a warranty check / replacement

• A 9.6 volt battery should read around 10 volts or higher after a full charge. If your battery only worked for a minute and has 4 volts then you received a bad battery and it should be returned for a properly functioning battery. Or your battery charger is not charging properly.
• It's simple enough to test. Get a volt meter and set it to DCV (DC Volts). Now turn the charger on as if you were going to charge the battery. Now place the positive terminal in the positive side of the connector on the charger. Do the same with the negative side. If it does not read AT LEAST 9.6 Volts (probably more like 10.2 - 10.5 Volts) then the charger is not putting out enough to charge the battery. A new battery charger will be needed.
• If the volt meter reads anything lower than 9.6 then the battery is bad and you will want to get it exchanged.
• Hope this helps and thank you for using FixYa.

Check the output of your voltage regulator. To do this, use a DVOM (digital volt ohm meter). Connect the red meter lead to the positive terminal and the black meter lead to the negative terminal. Put the meter's function switch in the "DC volts, 20 volt or higher range". Start the bike up and bring it to a fast idle. You should be reading between 14.5 and 14.8 volts. Any higher and your battery is being overcharged. If this is the case, replace the voltage regulator.

If the voltage is reading correctly, you may have a battery that is about ready to give up the ghost. I'd take it to an automotive parts store and ask them to load test it for me. Usually, they'll do this at no charge. If the battery is over two years old, it's possible that it's getting ready to fail.

Good Luck

the voltage read with a voltage meter on a healthy battery should read about 13-14 volts.15 and over is overcharging, 12 and under the battery is undercharged. you read no drop while bike was running, this is good, alternator is good.

#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.
