Class Code: 3642
Per NCCI's Scopes Code Description:
Code 3642 is applicable to the manufacture of dry chargeable or dry rechargeable batteries primarily consisting of the zinc-carbon, mercuric/silver oxide or alkaline type. These batteries may range in size from small circular coin or button size batteries to sizes such as AAA, AA, C, D and lantern. These batteries are commonly used to power a multitude of devices including but not limited to hearing aids, flashlights, photographic equipment, toys, video equipment and wrist watches.
The components of a battery generally consist of a container or case, a cap, electrodes, a current collector and an electrolyte. These materials may either be manufactured by the battery manufacturer or purchased from others. The battery manufacturer will mix chemicals and other materials to form the electrolyte mix and add this mix to the battery container. The assembly of additional battery components inside the container and the capping of the battery complete the operation. The battery manufacturing process is usually fully automated.
Refer to Code 3647 for the manufacture of storage or “wet” batteries.
