It works, but make sure you are charging a lithium battety ; otherwise, it will not charge a regular cell battery.

It seems to work great, but it will be some time before I will need to charge another battery. I'll review again after a few charges.

Like compact size, low-moderate charging rate (satisfactory). The charging cable would not engage with charger’s port, replaced cable, no issues. Happy so far, have charged 2 batteries. Will probably misplace the charger before I need it again ;?)

I really like the design of this charger. I was able to recharge the non-rechargable battery to my key fob.

This is a handy lithium button battery charger that can handle various sizes. I have a button cell tester and see that the charging works. However, the led light is supposed to turn from red to green when a charge is complete. Instead in my situation, the led light maybe turn green briefly, then go back to red. Or it may be red unless I adjust the connection, then it turns red. Also, the picture on Amazon is misleading in that it gives the impression that there are 3 leds that shows the state of charge like 1/3, 2/3, 3/3. But instead the only led that lights up in the middle one. Because of the led not working as described, I give the button cell charger 3 out of 5 stars.

Some of these chargers do not work zt all, but this one works great

Never knew they made such things to charge flat batterys

Product is defective. When you plug in, green light comes on. Put a low battery inn, green light stays on. Packaging fits product size. Small but, maybe to small to work?
