Unfortunately I had two units that did not work so I moved on to another brand. I'm sure that it was just a bad run of units, but the timing was not helpful for me at all...

I bought 3 4-pack of these ones for my Nikons SB800 and SB600. I keep quartets in use and charged them 4 a time using two chargers from different and good brand names. They took all time they needed (four to six hours) but at the end they had VERY SHORT life. I kept charging/discharging (as some reviewers recommend) but after at least eight cycles (per quartet) and having the same result (overall avoiding unnecessary risking my flashes among others), I decided it is time to buy a good brand name ones.

The batteries I received are superb, but there was a problem with the chargers working properly. The problem was solved by the fine folks at ADORAMA as soon as I called.Fine products, [...]

I use these to recharge 2700mAH rechargeable AA's for my Nikon flashes. I keep quartets of batteries together and charge them 8 a time using two of these chargers. The chargers work fine, generally taking four to six hours to charge a quartet. The included batteries were dead, so you might consider a different product. These chargers also work fine for AAA's.

The problem I have with this is that the power cord that came with it isn't working. I had to use a power cord from another adapter that I have in order to get it to work. The main reason I wanted it was to have a lighter weight adapter for travel. Since the power cord for the old one is the heavy part, it hasn't benefitted me at all. I'd have returned it but I received it late after I'd already gone on a trip and so I thought it was too late to return.

batteries seem to have some problem, sometimes they stop working until you rotate them around their contacts.

I charge these with the 4-battery charger, SKU #CTAMCACDC. I use them in my four Nikon SB-24 flashes. The batteries work fine so far, I haven't used them very long. Rechargeables in general recycle flashes faster than disposable batteries do, but they don't last as long. For the planet's sake, of course, as well as your wallet's, you should use rechargeables.

The first one or two times the batteries had VERY short life. After two complete charges/discharges they worked great. Don't give up on them too early.
