Forty batteries for less than the price of a takeaway? I'll take that deal faster than a TV remote disappears down the side of the sofa. I've now used these in everything from TV remotes and Xbox controllers to an electric toothbrush and a whole host of other battery-hungry gadgets lurking around the house. Every single device has fired into life without so much as a grumble. No compatibility issues, no issues with their size or fit, no mysterious tantrums—just reliable power doing exactly what it's supposed to do. They're the unsung heroes of the battery world. Not flashy, not demanding applause, just quietly getting on with the job like the dependable neighbour who always lends you a ladder. With a five-year shelf life, they're also perfect for stashing away for those inevitable moments when a remote decides to die halfway through the best part of a film. The industrial-grade build gives a bit of extra confidence, and it's reassuring to know they're free from cadmium, lead and mercury too. They've powered everything I've thrown at them, and at this price they're more reliable than my memory of where I left the TV remote. They provide reliable power and work well across a variety of devices around the home, including remote controls, clocks, toys, and other everyday electronics. The biggest advantage is the value for money. With 40 batteries in the pack, it offers a cost-effective solution compared to many branded alternatives, while still delivering dependable performance. The batteries are easy to store, have a good shelf life, and are ideal for keeping spares on hand when needed. I haven’t experienced any leakage issues, and they have performed consistently in all the devices I’ve used them in. I would happily buy them again.
