Reliable, Long-Lasting & Trusted Quality
The DURACELL CR123 (2 Pack) batteries are excellent and exactly what you’d expect from Duracell. They provide reliable, long-lasting power and perform consistently, making them ideal for cameras, torches, and other high-drain devices. They were purchased from Amazon and arrived well packaged and exactly as described. Dependable, good value, and a brand you can trust—highly recommended. 🔋✨

DURACELL CR123 (2 Pack) High Power Lithium Battery 3V (CR123A / CR17345) – Long life guarantee
Good price. Prompt delivery and undamaged. I use these batterie's for my alarm sensors. Last a good 12-15 months. Longer in areas that don't get as much foot traffic. Easy to use, just pop the old one out and pop in the new Duracell CR123. No issues with compatibility.

Watch out in the supermarkets too!
Right size, good brand and quality. Just the job. However, within 2 weeks of purchase, I saw this battery size front and centre of many supermarkets and DIY stores in my area where I was sure I had not seen them before. They were very reasonably priced in the shops too!

Suitable and fully compatible with hive window, door and motion sensors.
2x CR123 lithium 3v batteries, suitable and fully compatible with hive window, door and motion sensors. I was a bit worried when the battery package arrived taped up, but both batteries were fully charged. They are easy to fit, just slide it in between the contacts and I never see any battery leakage on the old batteries. I’m very happy with the length of time the old batteries lasted, over 7 years, so I always buy Duracell because you can rely on them, going for the cheaper battery never pays off, it’s just not cost effective, as you have to buy more over the years, when one Duracell lasts 7 years plus. I’d thoroughly recommend them.
