Should Lithium Ion Batteries Always Be Fully Charged

Lithium Ion batteries are notoriously mislabeled for capacity. I use these for camera stabilizers and flashlights, and expect performance. This Nitecore battery provides the full labeled current with minimal voltage drop. I have cycled one of my three four times, and performance was fully maintained. The only issue was with my chargers - the batteries would show fast charging, but never quite finish. Removing the battery and reinserting showed a fully charged battery, suggesting an issue with both chargers. Performance is very good.

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.
