CTA either has really bad quality control, or manufactures defective designs for this particular model.

The charger is wacky - the LEDs flip between "charging" and "charged" randomly, even when you put dead batteries in. The LEDs change state when you push on the batteries or change their order. On the first attempt at charging, after 5 hours, my batteries weren't charged. After a couple more tries it seemed to work, but now one set of batteries is losing its charge after 2-3 days. I'm not sure if it's a problem with that set of batteries or if the charger only charged them 50%.

I emailed CTA support and they said try spinning the batteries around and just wait 4 hours to see if they charge up (ie, ignore the LEDs). That seems to only have worked partially, as I mentioned. It's just not worth the aggravation of getting these batteries.

Bought these to go with a new digital camera. They arrived nearly dead; they would fire up my old camera almost through the boot. So, I decided to charge them. Installing them in the charger, as directed, showed them charging (red LED to green) in about 10 seconds. \But, they still wouldn't boot the camera. So, after some effort, I found that if you spin the just right batteries in the charger, they will switch from green back to red and charge. So, after about 5 hours charging the light switched to green. Yeah!

Now, I plug them in and they seem to work...until the third picture. Then the low battery warning comes on. These are not worth the trouble. Buy a name brand.

I bought this for my daughter's camera. She took a trip to New York, DC, Chicago, and Philly with her school. I did not want her to run out of batteries when taking a once in a life time trip or hassle with difficulty in charging them. It worked out amazing for her and luckily (I ordered item late) it arrived the day before she had to leave and with it charging 4 batteries at a time she always had charge batteries with two in use and two for back up and then could charge more when any ran out. It was great thanks very much she had an amazing trip with hundreds of pictures, not a memory was lost. Heidi Martin

I've bought this same package numerous times - and these batteries are one of the best I've ever been able to get; I also really like the small compact size of the charger.

I have about 12 of these batteries, both 2200 and 2700 mAH types. They seemed to work well initially but then quickly began to fail. Two issues cropped up. First, all of the batteries fail to charge (or discharge) anywhere near the rated mAH. I can't get more then 1000 mAH out of any of them any more, even after massaging them with a fancy charger, and they are still virtually brand new (maybe 15 charge cycles on them max). The second issue is that about half of them start reading 0V after sitting on the shelf for a weeek and it takes applying a voltage for a short while to get the battery to read > 1.2V again. Clearly there is something seriously wrong with CTA's manufacturing process. Do not get these batteries.

Had this charger for about 6 months now. The batteries seem to last about as long as any other set of name brand batteries I have. The charger just blew up about 30 seconds ago though. Actually, it was the transformer in the plug.

I think I'll pay for the name brand next time.

This does a good job charging AA's, but with AAA's, it just shows a green LED, indicating fully charged, but never charges the batteries. (Batteries were even their own brand.) Multiple contacts to CTA resulted only in autoresponses, never any useful information.

Cycle them a few times and then they seem to last for ever in my Canon SX10-IS....... Take plastic strip out from top of batteries to let it work. I found out you can not leave the Batteries in the charger for storage unless you use that plastic strip to keep the Batteries from cantacting the charger. It draws them down after awhile....

I paid $12.99 (free shipping) for this small, lightweight rapid charger with both home and car charging options and 4 long life batteries - a good deal! I had a similar problem as another reviewer when I first tried to use them, but once through a couple charging cycles they seem to work really well. Just took a bunch of pictures at the Coast all on one set of batteries without a problem. Recommended!

These batteries and their little charger have proven to be the BEST deal on the market to date! They WORK when all the rest of them "bleed-off" their charge for no reason other than poor quality of manufacture! After a month of "sitting" these batteries still retain over 80% of their charge, based upon an excellent "designed for the job" tester put them thru their paces. When I need MORE, I KNOW where I'll buy them!!
