Product Applications
Battery Holder with Fly leads
Battery Holder is one or more compartments or chambers for holding a battery. For dry cells, the holder must also make electrical contact with the battery terminals. For wet cells, cables are often connected to the battery terminals, as is found in automobiles or emergency lighting equipment.
History:
In the late 1800s patents were issued for consumer products like flashlights; patent no. 617592 dated March 1898 is for an early metal flashlight that accepted D batteries.
Some early 1900s battery holders were often no more than a cardboard box with copper contacts. By the 1920s, battery holders used twin metal clips (like fuse holders) to hold the battery in place while making electrical contact. Patent no. 1439429 was granted in Dec., 1922 for an assembly with two spring arm clips, a small switch and a lamp assembly on the end of connected wires.
The introduction of polypropylene in the 1950s and miniature batteries by Eveready allowed for the use of small plastic battery holders. These are still common in toys, decorations, and lighted or blinking items. In 1957, electric wrist watches gained popularity with the public.
Battery holders developed in parallel with batteries over time; as battery package sizes shrunk so did the holders. In the 1980s, the first circuit board mounting lithium coin or button cell battery holders appeared in the form of patent no. 4487820 by the battery holder manufacturer MPD.
The electronics industry now uses many surface mounted lithium battery holders or sockets. CR2/3A, CR1/2AA and CR123A batteries began in camera applications, but expanded into new markets like alarm systems, hand held computers, and keyfobs.
