9000 Mah Internal Rechargeable Battery

Higher mAh rating yields longer usage time than most other rechargeable.

Top quality, thin, has its own internal rechargeable battery that can be charged by USB or power plug, all included. Touch on and off , perfect light, no flicker. Big enough for one sheet of 35mm, 120, 4x5” or 8x10” neg.

The keys have a nice feel. I really like the internal rechargeable battery, instead of having to swap AA batteries like the older model.

I purchased this battery pack to replace an other one that used a rechargeable internal camera type of battery that would no longer hold a charge. To replace the battery was more than this unit cost. Love the fact this pack uses good old fashion AA batteries. Works perfect for my needs.

Works as well or better than OEM especially since it's higher a mAh battery.

Good battery, even at 6300 mah still better than my 7200 aftermarket

I purchased the 3400 mAh Rechargeable Lithium-Ion Battery for my LEDlenser ML6 Lantern so that I would have a spare. The lantern comes with a stock 3000 mAh OEM battery. Using a battery analyzer made for testing of Lithium Ion 18650 batteries, I placed both batteries side by side. I ran four tests that Charged/Discharged and Charged again. I wanted to both exercise the new batteries, as well as compare their performance 3000 mAh vs 3400 mAh. Surprisingly the 3000 mAh battery out performed the 3400 mAh battery by a great deal. This was disappointing to have purchased a top notch battery so I would have extra capacity for my ML6 Lantern. Perhaps the company should question their supplier. The 3400 mAh battery was left in the dust. 3000 mAh LEDlenser Battery 3400 mAh LEDlenser Battery Test #1 3263 mAh 3137 mAh Test #2 3269 mAh 3176 mAh Test #3 3357 mAh 3178 mAh Test #4 3316 mAh 3179 mAh

Battery works great but wished i would have bought the higher mAh like the 1200 to 1600 mAh battery.

Installation was simple and after charging it, the battery showed 8112 mah of battery capacity.

Great light but getting the rechargeable battery will make you use it so much more often.
