18650 Single Solder Tail Battery Holder

1、Product Description

Huizhou Antenk Electronics Co., Ltd. launches the single 18650 solder tail battery holder, a dedicated structural component designed to firmly fix single 18650 lithium cells and deliver stable continuous power conduction for portable electronic equipment. Produced strictly per dimensional drawings and precision tolerance standards, this battery holder adopts UL94V0 grade grey PBT plastic for the insulating base, featuring excellent flame resistance, heat resistance and anti-deformation performance under long-term working temperature changes. The conductive contact springs are stamped from 0.3-millimeter thick stainless steel, with multiple surface plating options including nickel plating and various gold thickness plating specifications to meet different anti-corrosion and conductive demands. Equipped with solder tail pins for direct PCB soldering installation, all structural dimensions are precisely controlled within specified tolerance ranges. The whole product complies with RoHS and REACH environmental regulations, and users can select tray packing or bag packing according to actual production demands, bringing flexible packaging solutions for mass assembly production.

 

This solder type battery holder boasts simple and reliable installation procedures for electronic assembly production. Operators solder the bottom tail pins onto reserved pads of printed circuit boards first, then insert a standard 18650 lithium battery into the holder cavity; the built-in elastic stainless steel contacts closely fit the battery positive and negative poles to realize smooth power output. It is widely applied in industrial control devices, digital household appliances, portable audio equipment, precision measuring instruments, electronic toys, communication power supplies and small energy storage devices. For prolonged safe service, users shall only adopt standard size 18650 cylindrical lithium batteries without oversized or deformed cells. Extruding the elastic contacts forcefully is forbidden to prevent permanent elastic fatigue, and the product should be kept away from high temperature and corrosive gas environments to protect plastic base and metal contacts.

 

Antenk owns prominent competitive advantages over common battery holder manufacturers supported by complete automotive quality management systems. Most competitors utilize ordinary non-flame-retardant plastic bases and thin iron contacts prone to rust and elastic attenuation, while our UL certified flame retardant substrate and stainless steel contacts maintain stable elasticity and conductivity for years. Our factory has passed ISO9001, ISO14001 and IATF16949 certification together with UL approval numbered E472792, carrying out full item inspection for each production batch. We support customized plating and packaging schemes with low minimum order quantities and no extra mold fees, while overseas suppliers always charge high tooling costs with long delivery cycles. Our precise stamping and injection molding technology achieves tighter dimensional tolerances, and finished products pass continuous salt spray tests for superior anti-rust performance.

 

Antenk executes full vertical integrated production workflow for this battery holder within its 10000 square meter factory with 250 skilled employees. The whole manufacturing process starts with independent precision mold development relying on over 250 plastic molds and 180 sets of hardware terminal molds self-designed in house. Qualified PBT raw materials are processed by eight Japan and Taiwan imported injection molding machines to form insulating plastic bases. Eleven high-speed precision stamping devices punch stainless steel sheets into elastic contacts, followed by standardized nickel or gold plating surface treatment. Automated assembly machines combine plastic bases and metal contacts into complete finished goods. Afterwards, comprehensive tests including dimensional detection, elastic force verification, coating adhesion inspection and electrical conduction testing are completed in our professional laboratory equipped with more than 20 testing instruments. All qualified products are coded with batch numbers for full traceability before packaging and shipment. We provide free samples, 2D and 3D technical drawings plus 24-hour global technical support, with over 70 percent of our goods exported worldwide and highly recognized by global electronic purchasers.
