Bulk Cr123A Lithium Batteries

[2 years] Very versatile, You can use lithium batteries to power it

[200 mAh] The Watson CR123A and CR2 charger work as expected. It is very easy to input the batteries and see the indicator status - which can't be said of other chargers.

[2x CR2] These are, as far as I can tell, the only rechargeables on the market that are 100% compatible with equipment that needs 3V CR123A batteries, and they are only available from B&H. Too bad about the lack of choice, but they do work very well and the capacity is as stated. I use these in my August lock, where it saves me a fortune, since the lock is hard on batteries. I also use the smaller CR2 batteries in various smart home sensors, where they likewise result in significant savings over the long run.

[8x AAA] Nothing beats these lithium batteries...they don’t die.

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

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

[0.25 lb] 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.

[7 lb] All lithium batteries have their pros and cons but these are the best of the best and they work just as well in -20 degree weather and in 100 degree weather.

[2000 mAh] This Lithium battery pack is one of the smartest things I have ever heard of for batteries. It charges very fast for its size and lasts very long! I would recommend this item to others!

[0.195 lb] Lithium Ion batteries are notoriously mislabeled for capacity. I use these for camera stabilizers and flashlights, and expect performance. This Nitecore battery provides the full labeled current with minimal voltage drop. I have cycled one of my three four times, and performance was fully maintained. The only issue was with my chargers - the batteries would show fast charging, but never quite finish. Removing the battery and reinserting showed a fully charged battery, suggesting an issue with both chargers. Performance is very good.
