Are 123 Batteries Rechargeable

Nicely made. Fenix rechargeable 123 cells fit smoothly and snugly.

Lightweight and does a nice job gripping the 123 cells I have used with it (Surefire rechargeable LiFePo 123 cells and Fenix 123 cells with the built in USB charger.

Quality rechargeable batteries.

These are the best rechargeable batteries I've ever used.

Rechargeable batteries - Great Life!!

The only way to go! Rechargeable. Why use batteries that need to be disposed of?

Good rechargeable batteries and charger.

the Eneloop Pro rechargeable batteries are the best there is.

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.
