  • These fit the Streamlight 88081 ProTac HL 5-X
Size: 1 Count (Pack of 12) Color: 14500 Battery
These are a lot cheaper than the Streamlight batteries and fit the flashlight. Not sure about how long they last but you get 8 batteries for less than 2 Streamlight brand.

  • EXCELLENT PRODUCTS, TRUSTWORTHY COMPANY
Size: 1 Count (Pack of 8) Color: 14500 Battery
I cannot speak to these exact batteries as I ultimately ended up with 18650 size but I have used them now and can attest to the quality and truth in advertising. Seller also showed they will go above expectations to get customer correct product (even when customer orders clearly marked wrong product). Thank you so very much, I am a friend to your business and your friends. ... show more

  • Charger works fine, batteries are junk
Size: 1 Count (Pack of 4) Color: 9900-18650-Flat Top Battery and Charger
I bought this so I would have extra batteries for my vape pen. Batteries claim they are 9900mAh compared to the 3500mAh battery that came with my vape so should last 2x my current battery. However, they only last about 1/2 as long. Keeping this only because the charger works.
