Got them for a vibrator. They work. What else u wanna know lol

These batteries were purchased to power my autonomous servant robot. Let me tell you, they were so powerful that it has developed new functionality. It was programmed to clean up around the house and bring me the occasional adult beverage. Now it has started calling itself Ultron and talking about world domination. It has some theory about a “sky net”... it’s so silly sometimes. Anyway.. great batteries!

Nothing special, but they do the job. My garage opener works again, thanks to these little guys.

Definitely worth buying.

Good price

Fast shipping. Good price on an irregular size.

Does exactly what is expected. Long battery life!

We have several remote-control units which require this type of battery. One had a dead battery, so I replaced it with one of these -- which solved the immediate problem. Of course theres no way to tell, after only a few days, how long they will last, so the specific ratings suggested are meaningless.

Very good, Thank you John.

Received on time and was as expected.
