These came in fine. I read various reviews where some stated that the batteries arrived DOA. I'm not sure how they attempted to test the batteries, but if they tried to use a battery tester that is not rated to test the CR1620 button battery; the battery will test weak or in the dead zone. For example, the Amprobe-250 is a great battery tester and will test button batteries, but it's not rated for the 3v button battery. And if you do test it with this battery tester it will test weak or in the red zone for button batteries. Regardless, I am very happy with this purchase. Read more

I’ve been using these coin batteries for my keyfob, and they’ve been fantastic. The batteries last longer than I expected and are great quality for the price. They fit perfectly into my devices, from key fobs to hearing aids, and I haven't had any issues with them not holding charge or draining too quickly. One of the things I really appreciate is how well they're packaged—each battery is individually sealed, so you don’t have to worry about them losing power before you even use them. If you need reliable, long-lasting power for small electronics, I highly recommend these coin batteries. Definitely a good value! Read more

It’s good however the juice in these batteries run out pretty quickly so you will probably have to change them kinda often but other than that they’re great batteries. I use them for my Mazda key fob because the car dealership was talking about $300. Hell nah! Read more
