3.7V 18650 Rechargeable Battery 9900mAh Universal Smart Charger for 26650 14500 16340 14250 (Button Top, 4 Pack+4 Bay Battery Charger)

Solid product. Charger is easy to use, and good quality. Will need your own usb box to plug into outlet. So far the batteries are working great after the first full charge.

The batteries and the charger have worked well. With a lot of these batteries the current ratings are often fictional, but my devise consumes a lot of power and works properly with these batteries.

So far so good work with my Halo light. Seems to charge and work properly.

Bought these batteries to replace older ones and of course I didn’t believe 9900 capacity, but I thought that at least it would be something decent, better than the standard one. Well, that was just a waste of money. These batteries do not last nearly as long as my old ones. I don’t think their real capacity is even half of an average 18650 battery. Unfortunately, I already threw away the packaging, so I cannot return them. I definitely do not recommend this product. Look for respectable brands. Typical Chinese fake info on the packaging.

Item was well p productacked, arrived quickly, and works well, much better than the charger that came with the flashlight.

Batteries are perfect for my flashlights. Charger is very fast which is a big plus. Charges all four batteries at once in no time. Charger and batteries are very high quality for the cost. Would recommend this product whole heartedly.

Works as indicated.We had purchased an item that required lithium batteries. The included battery charger never worked.Purchased this two battery charger with included battery and it works perfectly.I would recommend this product.One more thing. This product arrived the next day. Less than eight hours from purchase time.

Only 3 stars because the charger works. The batteries are garbage, hardly hold a charge. I have batteries older than these that still hold charge longer than these bought just 3 months ago.
