DURACELL CR123 (10 Pack) High Power Lithium Battery 3V (CR123A / CR17345) – Long life guarantee – For Cameras, Flashlights, Smoke Detectors, Small Devices – 10–Year Storage Guarantee - Leak Prevention

Was about to throw a giant calculator away as I assumed the battery would be worth more than the item itself. However, these batteries were so cheap I decided to give it a go. Not only is the giant calculator now up and running, but I believe with four batteries at my disposal there'll be enough juice to see me out and enough to pass on a working relic to future generations. Long live the Duracell LR44 (4 Pack).

I bought these little batteries for a kitchen scale, but I swear they could power a small moon. They’re like the espresso shots of the battery world—small, intense, and ready to make your gadgets feel alive again. Installation was easy: pop them in, and suddenly my scale was more accurate than my self-esteem. I’ve since used them in a laser pointer, a digital thermometer, and a toy that makes suspiciously loud noises at 3 a.m. (thanks, kids). They’ve lasted longer than some of my New Year’s resolutions. Packaging was secure, which is great because I didn’t want them escaping and starting a tiny battery rebellion. And being from a trusted brand, they come with that unspoken promise: “We will outlive your device, your expectations, and possibly your descendants.” If you need power in a pint-sized package, these are your ride-or-die electrons.

Well Duracell is meant to be the best quality and last the longest, but I have just purchased a battery case with a battery tester, and when I tested these brand new batteries, the needle stays in the red zone, it doesn’t even get to amber! None of these are fully charged! So are they old? I tested loads of other batteries to make sure the tester works properly. You pay for the name and expect the best, but I didnt receive that.

Great batteries, and ‘baby proof’. Took some getting into the battery, but that is how it should be to prevent a little one swallowing a battery. Good value for money.

You simply can't beat Duracell .Long lasting

Bought for car remote control and worked perfectly

Great value for money, arrived in good time. Hoping the last long time.

The batteries arrived promptly. Just what was wanted. Package fitted in letter box. Seemed to be a reasonable price.
