Lithium Ion Batteries Long Life

Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

I use this to charge lithium ion batteries for my Leica camera and my other small lithium batteries for my Panasonic Lumix camera.

This light is compact, very bright, and uses common AAA batteries instead of the more costly lithium ion rechargables. Overall a great little light for use around my shop. The only thing I don't know yet is how long the LED will last. However as a guide, I have had a 4 DCell LED Maglight for around five years and it's still going stong.

I LOVED this light. It is a great introductory prosumer light. It uses 6 AA batteries. (USE LITHIUM ION BATTERIES! they will last longer) it has a dimmer dial and a color temperature filter. I used it for a wedding last night and it worked perfectly. I like the lightweight design and I love the price. This is the best value if you need to save money.

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.

I’ve been begging for this (Lithium-Ion batteries) type of UPS for years, and it’s FINALLY HERE! With up to a reduction of up to 47% in Total Cost of Ownership (TCO) over the lifetime of the UPS, it’s almost a no-brainer. You do have to have a bit of extra rack space (3U instead of 2U) to mount this new unit, but the chassis DEPTH is only 12 inches!!! Pure sine wave output waveform and Cloud enabled “Smart Connect” makes for an almost perfect 1500VA UPS. Count me in!

These batteries can be used for different pieces of equipment that take the NP-F 6600mAh lithium-ion batteries and the charger it comes with is extremely compact and works great.

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

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
