Hot Batteries And Red Light Stays On When Not Charging After I have charged the batteries they are Very hot and smell a little. The red light is bright red when charging. When I take them out of the charger the light is still on but dim. This does not seem right to me. Can anyone tell me if they think this is a defective charger, or is this normal?

This may be a silly question, but are you charging *rechargeable* Duracells? Because if you're trying to put regular Alkalines in, that would certainly explain them getting uncomfortably hot and smelling strange. A charger like this should only be used for rechargeable batteries.

Thanks, I did call. But because I am charging Duracell I got no help. They will only help if I was using Rayovac batteries. I was told the dim light after is normal. So I'll just keep an eye on it when charging.

The manual says that the batteries can get WARM and that would be normal. I would call Rayovac's customer service...1-800-237-7000

The red light should go off when fully charged. If it doesn't you could have a defective battery that never reaches full charge. Try another battery before you conclude that it is a charger problem.

No. Batteries under charge should not get hot. When mine did, they held almost no charge.

When I have put two batteries into the charger that need charging, both light red. If I put one in that needs charging only that light comes up red. When they are finished charging the lights turn green. I've never had them flash.

Check to be sure first of all that the charger is operating by looking for the red light when its plugged in. Please note: these batteries are rechargable. If the red light it is on then its possible the batteries are defective, The batteries are enclosed in the main section near the handle. Check with Radio Shack to purchase the same batteries, you may also need a soldering device due to the battery tabs are sometimes linked together.... It may be a better idea to replace the entire unit!

The charger will flash red when the battery is mostly dead. As it's almost full it will flash green, however when the battery is fully charged the light will stay a solid green. Hope this helps.

The light will turn green when you put the battery into it, unplugged, but when you plug it in, the light turns amber. Then, when fully charged, it turns green again. I suspect it is something with current draw, zero current means green, positive current means batteries are still charging so amber. Very strange, but it works fine otherwise. Charge Times: My batteries are 4000mAh @ 3.7V. The charger is 650mAh at 4.2V. If you do the math, for two fully discharged batteries it takes 10.8 hours. Unfortunately, I charged them 'overnight' so I don't know exactly, but the 2 hours from John sounds lowball, unless he is just topping off their charge before using again.

The charger has warning lights to show when the battery is charged or if it´s too hot and it should be removed from charger (or even when it is defected). In general, I keep it charging for 3-4 hours. It gets fully charged without overheating.

Mine has a red light that comes on and stays on while charging. I will update when it's done charging to let you know what it does.OK, after charging the red light went off. At that point I disconnected from the charger and reconnected it, the light came on for a second and went right back off so it looks like you're fully charged. Hope this helps and enjoy!!

Dear Aya, That's normal. The new charger blinks instead of having the steady red. After the full charge you will see a steady green light. Please contact our customer service if you have more questions. all the best, Team Tendlite

No, it just stays red to indicate the charger is connected and working properly. I just charged mine for 24 hours initially and overnight since then to recharge. They recommend you never let the battery fully discharge.

Never had a problem w/the charger.just adjust the batteries.get a battery checker.best way to check any battery.also the batteries are old?best wishes.

OK Susie P., so you've used the battery until it is completely exhausted and now it won't recharge, correct? If you have checked to make sure there is power to the charger, the charger light should glow red when no battery is inserted, red while the battery is charging (a couple hours) then green when the battery is fully charged. If the charger glows red and you never get to a green light, then the battery is defective and should be returned for an exchange/refund.

HI - I am not an expert.....not even a novice....but we aslso bought these and when they are charging from any active USB port (i.e. - is your computer or TV turned on?) --it should blink red as it is charging and then green when fully charged......If not ...it is defective. Good luck

On mind there is a red LED that glows whenever it is connected to the charger. Unfortunately, the red LED never turns off or changes color to indicate it is fully charged. Does yours behave the same way?

This can often happen when your batteries (usually both in the pair) are in poor condition and will not readily accept a new charge. If you have a voltmeter you can check the voltage and if you find that even after charging the voltage is still close to zero, then this can give rise to this problem. Sometimes if the batteries will accept a charge you can get over the flashing red problem by swapping one of the pair for a different battery. However, due to the problem highlighted by the 'Engineer' reviewer for this product, if you charge two batteries together that are in a markedly different state of charge then you run the danger of overcharging one of them, and this will eventually shorten it's life. This is a drawback of this charger as it requires that you charge them in pairs. Check out the user review about this problem.

I have this charger (2nd one), the red light only appears when the battery is at its lowest charge and will begin flashing green as it charges up. When the green light stays on, you battery is fully charged.
