Don’t go to the Battery Stores for your next batteries. I did and they don’t last! Order the correct one from Fenix and It performs great.

I bought this battery to replace another one I had purchased which did not charge.

Having used fenix flashlights in the past I wanted a good, bright light for hunting animals at night and following a blood trail, after much research I choose the HM65-T, has both the flood and spot light, didn't need the red or colored lights and has good run times, also bought a backup 3400mAh battery to carry if needed. Also, took advantage of the 20% discount for first time buyers and the 5 year warranty.

Ive used the headlamp on and off for over a year and never charged it. When it finally went dark i was confused as it seemed to have an infinite power source!

Ordered this so I have a charged back-up battery at all times. Came fast. Great solid clear case to store battery.
Perfect
