Antenk battery holders are manufactured from UL rated 94V-O materials. Contacts made of high quality spring steel to assure reliable connections and allow contact resistance. Each contact is clearly marked with its polarity to assure proper battery insertion.
Lightweight and rugged, these PCB coin cell holders offer uniquely designed notched battery slot that assures quick and easy insertion and replacement of all major battery manufacturers' lithium coin cells.
Coin Cell Battery Holders
We have created a wide variety of coin cell battery holders for use in all types of devices, and from handheld medical devices to server motherboards we have solutions for any application. The ever increasing types, sizes, and sheer number of devices which use coin cell battery holders have been keeping us busy, and we have a similarly increasing selection of coin cell battery holder designs. After all, the perfect coin cell battery holder for a handheld medical device is going to be vastly different from the one for a server motherboard.
Lithium Coin/button Cell-Holders Battery Holders
Compact and vertical holders allow battery insertion and replacement from the top, making them ideal for high-density packaging
compact and vertical holders allow battery insertion and replacement from the top, making them ideal for high-density packaging, which maximizes board placement choices. The through-hole mount (THM) versions feature an "air-flow" support-leg design that facilitates soldering and quick battery insertion. The surface-mount (SMT) versions feature a "flow-hole" solder tail design for increased solder joint strength and are available on tape-and-reel.

Unique Coin Cell Battery Holders
Antenk has pioneered a large number of new styles of coin cell battery holders to suit the various needs of the electronics industry. Our Verticals are an excellent way to save space on a crowded board, while our Minis can save almost 3 mm in height above the PCB over traditional coin cell battery holders. Gliders are an excellent upgrade over coin cell retainers, offering more reliable connections while also having simple, tool-less battery replacements. Our newest technology is Snap Dragon, which adds a snapping cover to the traditional style of coin cell battery holders for increased reliability.
