CR2016

Works great, seems like a high quality battery for this price. Size is perfect for my booklight. Easy to remove and capacity seems to last a long time.

The media could not be loaded. I put these into service right away in my Boogie Board electric-rewritable board. They fit well and provided the correct voltage. They've been working great and was a tremendous value!

Quality is great. charging ability is great. Very good for it price. The size is good and battery. Life is good as well.

Item was as it was ordered. The packaging was secure and the batteries sealed. Only problem was the shipping package. It came with a small paperback book in a box big enough to hold 12 cans of soda. The packaging did not affect either product but was wasteful and made receipt in an standard mailbox impossible.

item as described. priced cheaper than many stores. good value

Works perfectly

I bought this 6-pack of Voniko 2016 batteries for a few different small devices, including a car key fob and a garage door opener. Despite the claim of a "7 Years Shelf Life," every single battery I tested was dead right out of the packaging.I tried multiple batteries in multiple devices, and they all registered 0 volts. This is completely unacceptable for a new product, especially one that claims to be "reliable" and "safe." The child-resistant packaging was also a major struggle to open, which just added to the frustration of receiving a pack of completely useless batteries.I wasted my time and money on this product. Save yourself the trouble and buy a brand that actually works.
