Nitecore NBP68HD Advanced Li-ion Rechargeable Battery Pack for TM28 TM15 TM26 TM36, TM38, TM39 (Upgrade for NBP52 and NBP68)

Light does not seem to be operating correctly. I bought a new CHG-AC-ADAPTER-NITE-TM but charging stem is 1/8 of a inch shorter than old unit and does not work.

Best battery setup, you can own, I've got a big yard of 18 wheelers and trailers here in Texas, I have to inspect breaks and inspect King pins all night, and I had a bunch of different flashlights, I bet I've spent $1,000 on flashlights, this is the only one for me, it goes all week and it's dependable

Bought this item for my TM 39 lite flashlight.
Fits and works perfect.
Run times now doubled for my TM 39 lite.
Now i have the choice between using the 4 cell
lite version or the larger 8 cell NBP68HD.
With the NBP68Hd battery pack the flashlight is well balanced head to tail. The lite version is a little nose heavy.
Shipping was fast and packaged safely.
Arrived in perfect condition.

Long lasting and well made.

This upgrade paired perfectly with my TM26. A solid solution.
