Charged the batteries fully in charger provided and after placing them in an Arlo unit they were dead again before the end of the day. Other batteries last for weeks. This is junk.

This unit worked as stated for the first 4 batteries I put in it.  After that even new rechargeable batteries will not charge.

Good charger but had trouble getting AAA batteries to fit in slots. Finally got them to charge but can't touch charger once they are in place. Works fine for the AA and 18650 Batteries. Haven't tried the C batteries as I never use them.

hello, I was shipped the batteries and charger it arrived on time, but after a week using the charger it stopped functioning correctly.
Description:the blue light on the charger stays blue and doesn't charge the batteries anymore. I tried using a different outlet i flipped the charger just in case it was not plugged in right but no luck. i'm not sure what to do. hopefully i can return it for another i'm sure i just got a one that was old . my last charger for batteries lasted me a good year and a half  until someone stole it, im sure they last fairly long.(also the item came with no instructions surprisingly i could make out what i had to do based on previous experiences but it would have been nice to be told blue is for charged fully and purple/blacklight is for charging)

I misplaced my  charger for a few weeks and  I received a generous gift card, I ordered this. When I received my order, I charged every battery including the 2 batteries I a read already had. Now I don't have to connect to the camera to charge anymore. It even folds up after use.

The batteries fitted the camera BUT not the charger supplied.  I kept the batteries and threw the charger in the trash!

I received my chargers two days ago.  I have been trying to charge my batteries since the chargers arrived. Charger will only charger them to 5%.

Contacted seller about charger not working. got a fast response offering to replace defective part. Turns out it was not defective. The charger seemed to not turn on when some batteries were plugged in. It turns out that the charger led for that port will not light if the battery is already charged, and this is what caused me confusion.  I found the best way to use it was to plug in the batteries, then connect power to charger.  Only those batteries that need to be charged light up. I drew lines from ports to leds so I know which batteries are charged. I also numbered the batteries so I can use them in rotation for better lifespan. I use these in My Syma X5C  Quad and have had no trouble so far. Very good flight time so far. Love having extra batteries always at the ready.

The batteries (that worked)  were great.  One battery showed up dead.  After contacting the vendor they quickly offered a replacement which has not arrived.  The charger. Is plain,  but effective.  I would buy again.

At first, the batteries would charge, but had a short operational life. After about 15 usages, the charger malfunctioned. It and the batteries became useless.

My home security system battery came time to replace so I figured I might as well install a new charger at the same time as replacement of old battery.  Everything worked .

I used this new charger for a new spare battery. During charging there is a red LED. After the charging is complete, the LED becomes green. I put the charged battery into my Nikon P600 camera; and the camera display indicated that the battery was fully charged. The charger prongs rotate/flip back into the charger body for safe storage. I have not yet used the DC car charger. Nikon should have included this type of charger with the camera, DUH. You cannot use the camera for pictures and charge the battery at the same time with the Nikon charging cable.
Thank you for your product at an affordable price.

This is an updated response. The first charger didn't work, so i contacted Customer service and they offered me a full refund or another charger. I decided to give it another chance and the charger came in less than 2 days. Worked fine and charged my battery. I very satisfied!

Have been charging since I received the batteries and charger. Took longer than I expected since it was called 'rapid' but the product worked as described. I like the color changes as batteries charge. Makes it easy to quickly determine which are finished.

I haven't read all the reviews (too many!) so I don't know if the following has been mentioned:
There's been several one star reviews and I think I might know why...
When you receive the charger, with batteries, there are two plastic, thin, spacers between the charger terminals and the batteries. These spacers must be removed before the batteries will charge. You should charge the batteries before using.
The other thing I noticed was the battery compartment in the charger is different than most, as the spring terminal is negative and the fixed terminal is positive. If a person was use to putting the negative terminal of the battery to the spring end, it would be backward. I tried it to see what the charger would do and the red lights come on and never go off. If that happens, look in the bottom of the charger battery compartment with a light and you will see the plus and minus. The positive goes toward "Duracell" and away from the LED lights.
I hope this helps someone.

As I had issues with my cell phone holding its charge; I needed extra time to test the battery.
So after extensive testing I am giving the Batteries 5-stars - my phone was clearly the problem not the batteries.

received 2 batteries.  Put both in the charger and it indicated they received a full charge.  On the first try the battery turned the unit on and when I was about to put in info the battery  died as the unit shut down.  Again put it in the charger until it indicated  a full charge.  Put it back in the unit and quess what - the same thing happened.  Used the  second battery - no problem on the first  try.  Recharged the first  again - to day it worked.  Let you know next week how it goes.  Tks  Jim
