EBL 3V Lithium Battery 4 Pack, 3Volt 800mAh 16J USB Rechargeable Camera Batteries Flashlight Replacement 123 Batteries with Micro USB Cable

My Olight H1 Nova headlamp came with an Olight-branded RCR123A that said 3.7V. But these EBL-branded ones say 3.0V. The EBL batteries work fine. The LED uses 3.0V. I think that the LED is equally bright with both batteries brands, at H/M/L setting, and both seem to last a long time. The size of both brands is exactly the same, and they fit inside the battery tube equally well. The charging via included cables is great. The tiny LED in each EBL battery is great. Recommend !!

purchased these batteries for some outdoor use equipment like flashlights, and some optics. while it does work in my flashlights (streamlight HL-X, and a walmart special light). for my optics though, that was a different story. I use an Eotech optic and wanted to try a rechargeable option to try and save some money on batteries, these batteries are slight larger than regular cr123's, which it states in the description when you go over the dimensions. gave it shot anyways to see if the slightly larger battery would work. They technically fit in the battery compartment, but you have to use a tool to get them out which can damage the battery because of how tight they fit. overall pretty good batteries for what they are. shorter life for lights but are great because they're rechargeable.

Tried these today - charged and inserted into a Switchbot smart lock. Lock shows 100%. Let's see how long they last. The capacity appears to be about 1/3 of the non-rechargeables.I like the fact that there's no need for a specialized charger, and one can charge it with any (older) USB cable. Two double-cables are included, which makes it even easier.Some people commented on these being longer than normal, but I compared with the existing CR123A batteries (non-rechargeable), and they are exactly the same size. Maybe people compared them to CR123?

They are working nicely and hold there charge

I use these for my security cameras. Slowly replacing other brands. They keep a charge longer than other brands.

I WISH THESE WERE CHEAPER BUT THESE ARE GREAT. I USED THOSE FOR MY DOOR LOCK PAD WHICH REQUIRES 2 BATTERIES. I CHARGE ONCE A MONTH .

Too wide. I bought these to put in a flashlight, but the charging port made them too wide to get easily in and out of the flashlight. I returned these.

Just received these and popped them into my generation 1 Ring contact and motion sensors. Voltage meter check shows that voltage does really range in the 3.04-3.06 range which is more unique for this battery class and works perfectly in the Ring sensor systems. A lot of the Li-ion CR-123A batteries you see for sale range in the 3.7V range which will not work in the Ring system and may actually damage the generation 1 sensors as the operating voltage is too high. In general, the high voltage 3.7V batteries simply will not work in the ring sensors at all so not even worth trying at the risk of burning out the sensor components. Of note, the non-rechargeable li-ion C-123A batteries will last about twice as long and cost about half as much as these batteries will, so factor that into the cost savings... you will need to use these 4 times to break even with the non-rechargeables, but anything after 4 times of use and you'll have gained value. These should realistically be good for at least 300-500 cycles so they should be a good value after breaching that 4 use threshold.
