Do Lithium Batteries Lose Their Charge

I have many many of these and they work well in the Olight I use them. Like all lithium cells, they eventually lose their capacity as the number of charge cycles increases, but it takes a while for this to happen and a replacement is inexpensive. The USB charging feature works well -- I use this almost as often as I charge these in a stand alone charger.

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

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

So far these batteries are exemplary. Hold a charge well and are very inexpensive for what you get. Do recommend.

Do know how I went so long with out. Charges really fast, no 4 to 5 hours waiting for my batteries to charge up.

I bought this to initially charge before installation, and then to maintain, 200kwh lithium solar batteries. The unit gets pretty warm and takes a bit to charge them fully, but it finally brings the batteries to the factory recommended charge point. It accommodates lithium batteries with Battery Management Systems (BMS), and it's important that a charger be compatible those systems.

These aftermarket lithium batteries are great! They hold a great charge and fit my camera perfectly!

I'm using enelop batteries for about 2 years now. Better ones i've have seen. Even when they aren't in use, they don't lose charge easily as the other brands.

I purchased a offbrand of this Sony battery for a much reduced price, but I never know when the battery will lose it's charge. I have 3 other Sony L series batteries and I always know exactly how much time I have left on the battery and it's accurate! This battery is great to go all day long if you need it to! The only downside is that it puts the Sony Z1U on the heavy side for a Steadicam unless you use the jacket and articulated arm-too expensive for me.

EXCELLENT QUALITY GLASS AND THEY DO THEIR JOB VERY WELL.
