Pay attention to button top versus flat top styles. .
Be careful to look at the batteries you are replacing. Some batteries have a “button top” while others, with the same battery number, have a flat top. In my case, I inadvertently ordered the flat top, not realizing there were two types of batteries with the same number and these would not make contact at the positive pole in my radio. I should have ordered the button top style . I was able to fix the problem with a small piece of aluminum foil to make contact. This is not a common type of battery such as AA, AAA, C, D, which all have a button top. They are made in two different versions. The company saw my earlier unfavorable review and contacted me with the Offer of a refund.

Dont waste your money
Batteries don't last long. You get what you pay for, and these are junk. Spend a little more and get something better. Even the shrink wrap label is all bulged and wrinkly which cause the Batteries to get lodged into the flashlight and require some smacking to get them out.

Doesn’t hold a charge for very long. Poor capacity.
After seeing this review, the manufacturer did come through with a refund, even though I’d missed the return window by a week. I do appreciate that, so I’ve raised this from one star to three. However, further research has shown that this can’t possibly be a 9900 mAh battery. It’s way too small to possibly have this capacity. I’ve picked up other batteries here on amazon that are slightly higher priced than these, but have much better reviews. Sometimes it’s just not worth it to shop on price alone.I am terribly disappointed with these batteries. The original battery that came with my rechargeable flashlight would last for about 30 after dark dog walks before needing a charge. Over time, that cut down to about a dozen walks, so I thought it was time to replace it. These new batteries last approximately 8 days before going dead. I’m better off with the original, three year old battery.

Prompt service
The batteries are fine however they don’t fit the flashlight we needed them for. However, they were as advertised and arrived promptly.

Runs my vape box the way it should run! The first 18650 that has done that.
