You can have 10 batteries for less than most manufacturers will sell you four, or 30 for around a tenner. If so, look no further than GP’s cheap and cheerful bundles. If you go through a lot of CR2032 batteries, perhaps in LED flashlights or electronic projects, then you might want to buy them in bulk. Key specs – Chemistry: Lithium Stated voltage: 3V Shelf-life: 10 years Features: Child-resistant blister pack They’re a bit too pricey to recommend for devices like a car keyfob, where they’re not in action all the time, but they’re great for wearables and high-drain lights where you want top performance for as long as possible. While the Panasonics had a higher voltage at the end of the full 12 hours, the Varta cells did a better job of maintaining their nominal 3V voltage over the first nine hour stretch. Even after nine hours in our LED booklight, the voltage remained at an average 2.99V, and it was only once we’d kept our test pair running for a further three hours that it dipped to 2.75V. Varta’s CR2032 batteries don’t come cheap, but their chemistry seems especially robust.

We then do the same after an additional three hours. We run this constantly for nine hours then remove the batteries and measure their voltage to check for any loss. We get the batteries in their standard packaging and install two in a clip-on LED booklight.

If it does, the batteries can react with fluids in the foodpipe to cause serious damage to the chest and windpipe. Apparently, this is a thing that happens, maybe because they look a bit like sci-fi smarties. CR2032 batteries are nearly always sold in blister packs, but some make it easier to get to the cells than others, while others have coatings to make them less palatable to any small children who might be tempted to swallow them. While there are differences in the internal construction and the Lithium chemistry, the main differences come in the stated shelf life, or how long you can store the battery before it starts losing charge, as well as the packaging and safety features. Best for child-safety features: Duracell DL2032 | £2.29 for two.Best for bulk buying: GP CR2032 | £2.99 for 10.Best for consistent power: Varta CR2032 | £5.67 for five.Best all-round CR2032 battery: Panasonic CR2032 | £2.60 for six. ![]() READ NEXT: The best power bank Best CR2032 batteries: At a glance We’ve tested a selection from all the major manufacturers, along with some smaller brands, to help you make the right choice. Like all good things, though, they regularly need replacing, and it makes sense to get the longest-lasting, most reliable CR2032 batteries you can find. Why? Because they’re roughly the size of a 10p piece, deliver a constant 3V output and last for ages, especially in devices that aren’t active for long periods of time. ![]() You’ll find the little coin cells in everything from car keyfobs to LED tea lights and torches, calculators to bike lights, and a wide range of security and wearable devices.
