Voniko CR123A Lithium Batteries (6-Pack) – Photo Non-Rechargeable Lithium Battery –3 Volt 123 Battery Lithium 10 Years Shelf Life

Great product and exactly as described. It arrived quickly and was packaged well. Quality exceeded my expectations for the price. Durable batteries that are perfect fit. I would definitely order this again and recommend it to others.

What to say about batteries? If the device works then I'm happy with the batteries. I will say that they don't last long and heat up quickly but I think it's the device (small flashlight - takes 1 battery) not the batteries. In any case, I will continue to use Voniko.

These are great for Ring products. I find them to be resonably priced and long lasting

Buying 2nd batch. These are a value for the money and consistent. I run 2 of these an old Surefire GRX2 Led 600 Dual for the dogs. Surefire claims 52 hours on low (15 Lumens) with their batteries and 1.5 hours on high. I run this on low 98% of the time. I probably got at least 30 hours on low before the high gets disabled . I got a couple of more hours on low probably at 50% -75% on low which is still bright enough for cars to see me and ~10 feet ahead if I really need it. I can go much longer but I swap it out. For ~$1.67 a battery I can't complain vs. $4.60 for a Duracell. The only con I noticed is it drains more in short spurts vs. longer use walks. Having said that the low and high and low are true and functional.

Bought these at the best price and qualified for overnight shipping. I needed only one battery to replace my Ring Flood/Freeze sensor. Works. I have plenty of extras for when this one dies. I haven’t needed one of these types of batteries for a long time.

Works as advertised

These batteries are a good price for CR123A batteries. Much less expensive than the energizer. I use these photo batteries in door/window sensors which are I guess a legacy design because I don't find them in the market anymore. Now these sensors use three AAA batteries or CR2 (which are physically smaller and not as powerful as the CR123A). The Voniko batteries fit these sensor devices the same as the Energizer.

Bought a six pack Voniko CR123A, Purchased January 2025, out of the six three were below voltage out of the package reading at 2.5 volts or lower, The three good batteries came in at 3.3/3.2 volts for measurement I used a Fluke 333 clamp meter and doubled checked with a Fluke 116 meter. The three “good ones” seemed to work okay, I did notice they do not last as long in the same application as a name brand battery. Batteries were used indoors in a climate controlled environment.(ring contact sensors 1st gen). low/no use windows I tried to reach out to Voniko back in February 2025 when I noticed the first dead ( low voltage battery but never heard back from them. Perhaps I received a bad batch other size batteries from Voniko seem to work as well as name brand ones. But a 50% failure rate out of the package.
