LITHIUM CR2450

By our assessment, LITHIUM CR2450 is a coin cell for small electronics, the sort of battery used in remotes, key fobs, scales, and similar low-drain gadgets. Its strength is simple: it gives compact devices a neat, sealed power source that is easy to slot into a tiny compartment. The downside is just as plain, because coin cells are not rechargeable and once they run down you replace them rather than revive them. In practice it is the kind of thing you only notice when a device starts acting dead and the fix is one small cell rather than a new gadget. Against bigger batteries it is all about size and convenience, not long runtime or high current. The name itself includes 2450, which is part of the catalogue label, so it is not a measurement to read into. It suits people dealing with compact devices that take this format and not gear that needs serious power.
