Panasonic CR2032 Battery (2 pack) - Lithium Coin Cell, 3V

Product Information

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. Interestingly, hemp batteries are non-toxic and have outperformed lithium batteries in tests. Just sayin’. Q: How do you dispose of CR2032 batteries properly? Lithium is harmful and environmentally costly but very widely used. The world’s growing problem with lithium batteries is well-documented. CR2032 batteries also use an array of other common battery materials like zinc and manganese dioxide.

Regardless, shelf life is the amount of time it takes for the battery to lose 10% of its initial capacity.

Sources:

A: Any lithium battery should be recycled at a battery/device drop-off location. To find one near you, go here. Lithium and other toxic battery chemicals leech out of punctured batteries in landfills, making their way into soils and waterways. Q: How long should a CR2032 battery last? Third, and most important, these are batteries with staying power. At the nine hour mark they were level with the Duracells, still putting out 2.96V, but by 12 hours they were slightly ahead, at 2.41V. They don’t quite have the consistent output of the Varta cells and fall just behind the Panasonics, while the shelf life is eight years rather than ten. However, if you can’t get your hands on the Panasonic CR2032s, the Energizers are a great second choice.

Capacity is measured in milliampere-hours (mAh). Many CR2032 batteries have between 190 and 225 mAh capacities. What does this mean? Essentially, a CR2032 with a 200 mAh capacity can deliver 200 milliamps of current for 1 hour. Or 400 for half an hour. Or 100 for 2 hours. And so on. Get the picture? Shelf Life — Passive discharge limits shelf life in batteries. CR2032 batteries generally discharge at about 1% per year. Under some conditions, the rate may be a little higher. Instead of churning through CR2032 batteries (dropping the dead ones off at an approved recycling center), try a rechargeable LIR2032. Be aware, there are a couple critical performance differences between the two. A: A CR2032 battery, often called a button cell battery, is a 3V cell often used in small electronics. Watches, small remote controls, wireless doorbells, calculators, etc. usually use lithium CR2032 batteries.Temperature Tolerance Levels — CR2032 batteries have a temperature tolerance from anywhere between -22- and 185-degrees Fahrenheit. Not every CR2032 battery will tolerate such extremes, but many can handle a very wide range of temperature.
