Voniko CR123A Lithium Batteries (6 Pack) - Non-Rechargeable Lithium Battery - 3 Volt Lithium Battery 123 Lithium Battery 10 Year Lifetime

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.
