Customer Review: Avoid these!
Summary: 1 Stars
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.
Customer Review: Fail to charge to specified capacity
Summary: 1 Stars
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.

Summary: 1 Stars
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.
