Rechargeable 36V Lithium Ion Battery

[0.155 lb] Rechargeable lithium-ion battery used for Olympus camera works well everytime.

[11.1 VDC] I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.

[Black] 50W is very loud! Lightweight Lithium Ion rechargeable batteries. Very easy to use. I especially like the 10 second built-in memory.

[0.025 lb] This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

[0.1 lb] 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
