I’ve been using this battery daily for a while now, and I’m honestly impressed. It holds a charge way longer than others I’ve tried!

They replaced the defective unit free of cost I changed the rating to 4 from 1 based on their customer support. Let’s see how the new unit works.————-I bought u-bolt-pro-WiFi by u-etc back in March 2024. The app recommended that I need to buy u-tec lithium batteries too for better performance. Two and a half months later, my lock stopped working. Called support and they suggested, I should just use normal alkaline batteries. The lithium batteries are u-tec branded. What a waste of money. He would refund or send me replacement batteries.

Hi all,UPDATE: I thought I would write an update on the batteries from U-tec. While the batteries didn't last long, the company wrote me and asked me how they can better support me with the batteries, and they sent me another set of batteries for free. That's above and beyond service. Thank you U-tech!Thoughts these would have been perfect to fit my current U'tech key lock entry, but these batteries lasted less than a month. Any regular batteries work just as good or better.

5 out of 5 stars - Exceptional Performance and Long-Lasting!I'm thoroughly impressed with the U-tec AA Ultra Lithium Battery (Pack of 4)! I've been using them in my Blink camera for a month now, and they're still going strong! The battery life is incredibly long-lasting, and I'm blown away by their performance.These batteries have exceeded my expectations, and I'm so glad I made the switch. The fact that they're still powering my camera after a month is a testament to their quality and reliability.Highly recommended! If you're looking for batteries that will keep your devices running for an extended period, look no further than U-tec AA Ultra Lithium Batteries. They're a game-changer for the price!

My digital door-lock needs 4 AA batteries to run and as usual I was using alkaline AA batteries. Unfortunately, these batteries do not last long enough (maybe due to heavy usage in our door system). Frustrating, I opted for these lithium batteries to try on. It was costlier than Alkaline ones - no doubt. But, four months have passed, batteries are running strong till today. It is surely four times more durable over normal AAs. I am sure it would run for a few more months, too. And in comparison, cost wise, it is better too.I will go for these lithium batteries of this make, once again when needed.
