123 Lithium Batteries

Very versatile, You can use lithium batteries to power it

Nothing beats these lithium batteries...they don’t die.

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 already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

installed this cable like 123

Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.
