Rechargable 123 Batteries

Well, these are the best rechargable AA batteries I know... Not much else to say actually...

I love that they are rechargable, and you don't have to go out and buy new batteries!

I usually use Watson Rechargable batteries but this was such a good deal that I couldn't resist!

Excellent for checking remaining charge of both alkaline and rechargable batteries of all kinds.

I bought an LED video lamp and since it takes 6 AA batteries, I was trying to think of the most efficient way to use it. Buying 6 regular AA batteries definitely isn't the answer.. The light had the option of a few different rechargable batteries from PnS cameras, but I didn't have any.. Looking into them online many of them because of their very low cost were junk and didn't work that well.. Then I remembered that I use these rechargable AA batteries in my SB700 flash so why not in the LED lamp.. Worked perfect.

I have multiples (5) of these which I have purchased over the past 4 or so years. They charge 123/16340 and 18650 Li (I have not used them for LiFePo cells such as the SureFire 123 batteries however) and IMR 123 batteries nicely. I have used these chargers with Fenix (16340), Olight (IMR 16340) and Surfire (18650) batteries and they have worked well. The display is very helpful for getting a sense of where the batteries are in the charging cycle. This charger does not, to my knowledge recondition batteries. Also, there may be calibration differences among charger or even in one charger itself -- individual charger may read cells' voltages differently including reading them differently in the charger's own left and right channels. This has not been any sort of a problem, as far as I can tell, with the cells I have been charging. Another small niggle is that the input cable fits a bit loosely into the charger.

I was paying up around twenty dollars for the 123 batteries that you can't recharge and didn't last long. The watson dual rapid charger works great for me. Great product. Would buy again.

Very nice for organizing 123 batteries, I have a number of these, though I initially did not think I would like them because they seem more open to the environment than for example a clam shell type case. But they work great, holding the batteries securely and make the individual cells labels apparent. These cases allow for the batteries to be held either end up which makes designating exhausted cells easy by placing them in the case inverted relative to charged cells.

I have been using my marshall monitor for a while now. I have not been able to get rechargable batteries to work very well with it so I was either connecting it to an external source or using regular batteries. I found this adaptor and it fits perfectly. I have a few LPE6 batteries which provides plenty of power for my needs.

The above review says it all. You still need rechargable batteries to run the flash heads computer but they last forever. I change the Sanyo Evelop onboard AA's after like 400 shots. The SC powers my sb800 all event long without a worry of ever running out of flash. It recharges super fast also in the rare cases I have run it low on a job.Fits perfect in the stock Nikon case also. Dont know why I wasted so much money on batterys chargers etc should of just purchased this long ago. It will pay for itself in a few years
