Working great so far.
This was the 2nd ever rechargeable Lithium battery replacement for standard batteries, I've purchased so far. My first was 9V rechargeable replacements and they've worked great. This have been recharged twice so far and work great.They last quite long in low current uses. NiMH and NiCad batteries only worked well in high drain applications, but are terrible in low drain applications since they self discharge too quickly. These lithium batteries don't self discharge like that and can last quite a long time. I expect them to last a decade or more, much longer than the NiMH and NiCad batteries. I can save a bunch of waste and some money by not needing to buy too many alkaline batteries in the future.

Really good little batteries
Need batteries, but if you don’t have time to go to the store to grab batteries, you have these guys which I rechargeable by USB-C connectors

Not really what I was expecting
First of all...yes, eventually these will save me $$'s. However, I did expect them to last longer than 16 hours on a full charge. I don't know about anyone else, but my batteries take at least 2 to 2 1/2 hours to charge. Not really bad I guess, but a good bit longer than they advertise. I am using three of them in a little night light. On a fully charged set of three batteries, they last about two 8 hour nights. I really thought they would do better than that.They are easy to connect to their little charger, and if you miss seeing the light go from red to green indicating they are finished charging, they will cool in just a few minutes. NOT that I would leave them on the charger longer than necessary on purpose. I do NOT charge them when I can't be nearby and awake.I guess, all that said, I do think that the price is fair, just take a lot more charging time than I bargained for.

good batteries
These arrived quickly and took a charge with no issues. I have been using them and have had no problems as of yet.

I love these USB-rechargeable batteries
What a great idea! Batteries that you can just plug in to any USB charger directly. As my regular batteries got used up I slowly replaced them with these USB rechargeables and I couldn't be happier. Bravo

Works Very Well!
Bought them to put in my meter because I was tired of people leaving it on and not working when I needed it. Now as soon as I’m done with the meter, I pull the batteries out and plug them in to the charger. Guaranteed to work 💯% of the time!!!
