3.7V 14280 Lithium Battery Manufacturer - Small Size Power Solution for GPS

The 14280 is a lithium-ion cell wrapped in a tiny cylinder—14mm across and 28mm long—so it basically slides into any tight spot a GPS tracker or wearable gadget demands, and the 3.7V nominal rating gives you 310mAh minimum with a typical 320mAh on tap, using NCM cathode matrial that holds up through 500 cycles or so, though it's not built for heavy draw since max continuous discharge tops out at 3C.

Most of the clients we see using this are stuffing it into portable electronics—think medical monitors, those slim Bluetooth tags, or location beacons—where every millimeter of space counts, and they're usually pulling form a steady stockroom for assembly runs, not prototyping one-offs, because the raw cell format means you need your own protection circuit or you're integrating it into a custom pack.

our company have these in stock normally, raw cells wrapped in a poly film sleeve, and the MOQ varies—buyers ordering 500 units or more get better per-piece pricing, while smaller lots (try 100 pieces as a starting point) are fine for pilot runs, but confirm lead time if you need them in under 2 weeks because transit can bump that to 20 days depending on your destination.

Charge it at 4.2V with a decent charger, keeping temps between 0°C and 45°C during charging, and it'll discharge happily down to -20°C—though capacity definitely drops above 0°C—so this isn't a battery you'd push hard in a freezer for sustained heavy load, but for periodic location pings in a cold warehose, it does fine.

Actually, one thing we've noticed is that some buyers try to solder wires directly to the terminals—not advised, since the lip on the positive cap is thin and the negative can scratch, so pre-welded tabs or a holder are worth the investment for reliability, and every batch ships with paperwork covering UN38.3 and MSDS.
