SHENMZ 16650 Protected Button Top Battery 2500mAh 3.7V Lithium Ion - High Capacity Rechargeable Batteries for Flashlights, Headlamps, Bike Lights 【 2-Pack】

Really like these. Hold a charge well.

Good batteries

Batteries are performing as expected so far

Fit my SUREFIRE perfectly. Charged quickly, light is bright & rechargeable plus plus.

Checked the charge and it was fully charged.

Batteries worked fine in my surefire flashlight, the light isn't quite as bright with one of these 16650 replacements, but its way less expensive than using a123 batteries all the time.

I’m always up for having a few extra batteries on hand, but this isn’t one I can pick up easily. If I went to my local hardware store, the cost would be prohibitive. This I know because I’ve had to purchase a couple of smaller ones and was surprised at the exorbitant pricing. I do like the fact that these come in a small plastic case, a handy feature I like. I have a couple of flashlights that use the 16650 batteries and do like these. I have a charger for these and checked out the charge when they arrived. They were fully charged, something I appreciate and like. These can be recharged hundreds of times, yet another feature I’m into. Every now and then we get a battery or two that’s a dud, but for under $20 these are reasonably priced.

Replacement Batteries Well worth the money. Excellent delivery and shipping. Would highly recommend.
