Are Triple A Batteries Lithium

Pretty good. It also charges triple A batteries as well.

Very versatile, You can use lithium batteries to power it

Nothing beats these lithium batteries...they don’t die.

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.

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 love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.

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

I use this case to carry my Paul C Buff Vagabond Mini Lithium Batteries. It's the perfect case.

All lithium batteries have their pros and cons but these are the best of the best and they work just as well in -20 degree weather and in 100 degree weather.
