Small Battery, Big Benefits
The specialty battery category offers a wide range of applications, to say nothing of sizes, shape and chemistries.
These batteries include the coin or button cells, the smaller round cells and lots of other shapes. They're supplied in chemistries that include alkaline, lithium, zinc air and silver oxide.
But it's a profitable category and less confusing than it looks. Demand in an aging society includes medically-related devices, such as hearing aids and blood pressure and glucose monitors. Replacement batteries for these devices alone are already close to a $400 million market in the U.S. and is growing fast.
