Do Lithium Ion Batteries Lose Charge Over Time

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

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.

Hi Folks. Yeah I know they are Lithium Ion. However, they hold a charge for a very long time and will take a ton of pictures too. My wife uses the small ones pictured above and I use the big ones. We both shot Canon. I have never had one get even a little warm on me. Regards to all, OldeBear

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.

As stated in the headline, it works, charges slower so the lithium-ion batteries last longer. I have the fast charger but bought this to condition the batteries over time. Fast charging all the time will shorten the life of your $$ battery.

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.

Having this as a spare battery was great - maintained its charge as well as the original Pentax lithium ion battery and let me continue with my photography.

The Watson EN-EL9A Lithium-Ion Battery Pack (7.4V, 1000mAh) is a dependable battery at a great price point. So far, these are as dependable as the OEM batteries I've used. They charge quickly with a long-lasting charge cycle. Excellent functionality, value, and price. Highly recommended!

I use this to charge and recharge my Anton/Bauer Titon 90 Gold Mount Lithium-Ion Battery. It's smooth to use and easy. My life would be incomplete without it. I love it more than my own mother. It has never failed me. Kinda dumb there's not another way to charge the battery, but whatever.

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.
