16650 Rechargeable Battery with Battery Charger, 16650 Protected 3.7V Rechargeable Battery 1800mAh (2 Pack) - [Replacement for 2 x CR123 ]

Love the fact that I am no longer throwing away worn out batteries from my flashlights any more. Now I just charge it up and use it without any worries. Then after usage, if over an hour of light I just throw it back on the charger and I am ready for another night.

Had it for a while no and it hasn’t blown up yet so I’d say it works.

Nice little setup. You get 2 batteries so you can rotate them and always have power. These will pay for them selves after about 3 recharges. hard to beat. I would definitely buy again.

Works as it should in my Rayovac flashlight!

Easy to charge but loses charge quickly

Feels very cheap but gets the job done

I'd give it a 10/10 mainly used in tactical lights. It is still working hard to this day!

I used these batteries in my Stream light Pro-tac 2L X, and the light flickers. It does not remain constant or at the correct output. I've also tried these batteries in my surefire G2x, and I've had the same results.These batteries are a good concept for replacements of (x2) stacked 123A's but they don't work well with high output flashlights. Wouldn't rely on them staying constantly on.
