I bought about ten sets of these batteries, I figured NiMH cells were all pretty much the same. I was wrong. After two break-in cycles on my Maha C-9000 charger then a refresh and analyze cycle it reports average capacity as approx 1200mah. The actual capacity ranges between 700mah and 1500mah.

They also initially had problems charging in the charger, it said they were full but i'd only get 5 full power flashes from a Canon 580EX before they wouldn't charge the flash any more. Only the breakin cycles made them work at all. Once I had them charged they really just didn't work well, being very low capacity and just generally not working.

I emailed the manufacturer's support email address and didn't receive a response.

I wouldn't recommend purchasing these batteries.

I bought many sets for my speelites and noticed they didnt hold a charge very long. I bought the la crosse charger which test batteries and they tested between 60 and 1500 mah and they claim to be 2700. these batteries should be taken off the market! the only cool thing about the company was that they refunded me my money.

I had a set of these batteries that served me well for years. But the replacements would not charge properly even in the CTA charger and did not hold a charge. I had to recycle them and get a different brand.

I bought these in 2008 for use with a digital camera and used them for several shoots a week and they just now (04/2010) started to fade. I just bought more and they are working great. I recommend following the initial charging instructions very closely or your batteries won't work well. Hope that helps! Peace!

One of the batteries was bad out of the package, would not take a charge.

I bought these a year ago for various electronics (CD player, digital camera, etc.). They're easy to use, recharge quickly, and hold a charge for a long time. They've worked great for our family.

I bought these with the CTA charger in 2006 - it's now late 2009, and I've had no trouble with them.
I suppose I have only recharged them ten times or so, but they seem to last very long and I only
rated them 4 out of 5 because I haven't used them vigorously and I have no way to measure current
or other technical aspects. I just checked them and they were charged 2 months ago and my flash
unit works just fine with no delay - just as if the batteries were totally fresh.
I'd buy them again - in fact I am buying a backup set.

They hold a charge really well. And These are the best AA NIMH batteries I could find. They charge good and seem to last a nice long time.

I used these as backup batteries in my canon flash. I used them three times and tried a fourth time and they were dead ~11 months from purchase.

Seems like pretty premature death to me, but R.I.P.-off

I bought these batteries from another source not on Amazon in the fall of 2010 and was excited at the 2700 mAh ratings. Now a year later the 4 pack I bought are worthless... won't charge or hold a charge for more than a few photos.

I had bought other re-chargeable batteries from "well known" brands during the same time frame and all still function very well.

Will not be buying CTA products again...
