Fenix ARB-L18-3400 Battery

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.

HM65R-T headlamp

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.

Battery Life

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!

Perfect back-up

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

Long lasting

Son gave me Fenix headlamp with one of these batteries in it. After Hurricane Ian, recharged it, turned on the small low beam, left it on for 5 days and 22 1/2 hours, before it noticeably started dimming.
