20 Most Recent Duracell AAA NiMH Battery Charger with 4 Rechargeable AA Battery Questions & Answers

What did the manual say about operating conditions or how long it takes for the batteries to charge. Let that guide you.

The flashing red probably means that the charger is working correctly and is indeed charging the batteries. The light should turn green when charging is complete after anything from 1 to 16 hours depending on how this charger works.

Do the following test: Fit the charger with your batteries and connect it to the mains. After 1 hour check if there is a detectable temperature rise in the batteries. You can do this without interrupting the charge cycle by touching the cells with the back of your fingers. If the temperature is still low, let it continue for another 15 hours or so, checking every now & then for any temperature increase. Should the temperature rise more than a few degrees, then stop the charging by removing the charger from the mains. Should the red lamp remain flashing after 16 hours, then I suspect you to have a defective charger.

When the duracell lights blink during charging, AT YOUR OWN RISK, try a reverse charge. Instead charging positive to positive and negative to negative, try positive to negative and negative to positive. I did this for 2 minutes. This solved the problem. After the 2 minutes, I gave the batteries a normal charge. You will have to force the battery and charger contacts to touch.

I wont exactly call this solved but I called duracell and they think the batteries are old. They are sending me a new set of batteries.

put one battery at a time ,when it turns red that battery is bad.

I had the same problem. 1 of four way's can fix it. #1 Put a batt. that has a little charge in that flashing spot 1st. and see if that works. #2 put the batt. in that flashing slot first and then in the 1st slot, If that did'nt work, #3 Put Batt. in backwards for 1 sec. in and out fast. and I do say very fast, In that flashing spot. #4 buy a new one. The one that fixed mine was #1 and it stoppppped flashing, The order I put them in was - 3-1-2-4 I put in #3 batt. first, it was the one flashing And it worked, You may have a bad batt. or it's on it's way out, but try It. worked for me!

Do not use leaky batteries. The chances of a leaky battery still being useable is slim, and generally the chemicals that spill out is not good for you and not good for the electrical appliances that use them either.

Yes, this will charge any AA-AAA Batteries. Typical charge will be about 14 to 18 hours

return it to the store oir replace it it isnt working

You broke it. there is no fix.
The batteries you put in it that blew were resisting the charge and fighting with the unit and most likely burnt up some electronics inside the charger.
I would not use it at all or even try to use it. You may cause a fire or get zapped.

Rechargeable batteries just don't last long in digital cameras unless it is a battery pack made specifically for the camera.
