Most Helpful Positive Review 18650 USB Batteries
I recently purchased a ProTac HL 5-X flashlight. I highly recommend purchasing these rechargeable batteries. I purchased mine with rechargeable batteries and then purchased 4 more as spares. Takes 5 hours to recharge them. Run time on “High” is approximately 1.25 hours. Having spares for me, was a must. It’s an awesome flashlight, I use mine at work. Contrary to what you might be told, or have heard, regular 18650 batteries will not work with this flashlight.

If you buy the flashlight, buy the batteries+

by OLD MAN, Verified Owner from VA, United States Written on March 20, 2026
It just makes good sense to buy backups for a rechargeable flashlight. You need to have them ready if the battery in the flashlight gets low. Over time, we shall see how long battery life is.

perfect way to save money

Recharge fast enough, work for a long time, and will save you cash if you use your duel fuel flashlight frequently. Wish more lights safely accepted these. Grab them while you can, they’ve been 100% reliable for me.
