A five-pack of CR2025 lithium coin cells, the 3V button battery used in car key fobs, remote controls, watches, calculators, small toys and some medical devices. CR2025 is a standard size, so these are interchangeable with any other brand's CR2025, ECR2025 or BR2025 cell. Lithium coin cells hold their charge for years in storage and deliver a stable 3V, which is why they suit low-drain devices left unused for long stretches. The trade-off against rivals is simple: generic cells are cheap but vary in shelf life and consistency, while name brands cost more and are more predictable.
