EBL3V Lithium Battery 4 Pack, 3Volt 800mAh 16J USB Rechargeable Camera Batteries Flashlight Replacement 123 Batteries with Micro USB Cable

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 .

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?

Awesome sauce

I've been using these for my handgun and shotgun (one and two batteries respectively) for a few months now. They've never died on me, and I've had no reliability issues, but I keep them topped off on a strict two week rotation just to be safe. The lights seem about as bright with these as they do with disposable batteries. I still think of them as semi-disposable, since I'm sure they'll lose max capacity with time, but their functional lifespan will likely be greater than the disposable ones. Plus, I'd rather have an old rechargeable battery that only lasts five minutes than a dead disposable battery that lasts zero minutes.

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.

A quick top off once they arrived and then the moment of truth…Can confirm they fit a Streamlight TLR-1 HL (and a souped up clone…Goonbeam Short). Also fit and functions in my DBAL i2 (9007). I was worried that the battery cap on the DBAL didn’t screw all the way down and waterproofing may be affected but a quick comparison to a standard CR123 proved that wasn’t a concern.Looking forward to running these in my lights now. Should be easy to routinely top off batteries to ensure full power as needed and a big cost saver. Biggest concern was would they fit what I needed them too and they did.

Cheap cheap cheap. The batteries don’t last 15 mins in my flashlight, and have to recharge. Save you money and buy name brand. These are not worth the money IMO….

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 !!
