Custom 3.7v LIR16340 Lithium Battery Manufacturer in China
A 16340 lithium‑ion battery like the LIR16340 is a compact rechargeable cylindrical cell with a nominal voltage of 3.7 V and a diameter of ~16 mm × length ~34 mm, widely used as a high‑energy alternative to CR123A primary cells. Typical capacities range around 600–900 mAh, and charge termination is at about 4.2 V, with discharge cutoff around 2.5–3.0 V under standard use. These batteries deliver stable power in small‑form‑factor, high‑drain devices such as tactical flashlights, handheld electronics, and precision instruments.

Advantages of Our INR16340 Lithium Battery
Our INR16340 lithium battery features a built-in intelligent protection chip and pressure relief device that automatically prevents overcharging, deep discharge, and short-circuit risks. The thickened metal shell provides drop and collision resistance, while the temperature sensing element and control module adjust current in real time to ensure a stable power supply for compact devices.
Using advanced alloy welding technology and multi-layer reinforcement, our INR16340 battery maintains stable performance even under high-load conditions. Rigorous testing shows it retains over 70% of its capacity after 1,000 charge/discharge cycles. Fast-charging technology reduces charging time significantly.
Thanks to high-density energy storage, our INR16340 cell can reach up to 700–900mAh, providing long-lasting power for flashlights, portable medical devices, or vaping devices. Its compact size is perfect for small electronics that demand reliable, continuous energy.
Supporting 5–10A continuous current output and high instantaneous burst power, the INR16340 is suitable for high-drain small devices. Its low internal resistance ensures stable voltage and 5–7% higher energy conversion efficiency compared to conventional cells of the same size.
Rechargeable and durable, our INR16340 reduces long-term costs by replacing hundreds of disposable batteries, cutting battery waste by over 90%, and supporting sustainable usage in small electronics.
Each INR16340 battery meets UL1642, IEC62133, RoHS, CE, KC, BIS, and ISO9001 certifications. Batteries are tested for voltage accuracy, cycle life, and temperature extremes to ensure reliable performance.
With a standardized flat-top design and pre-set soldering points, INR16340 batteries are easy to integrate into battery packs for flashlights, cameras, and other small devices. They fit most standard 16340 slots and can be installed quickly.
Ideal for compact devices like tactical flashlights, small medical instruments, drones, vape devices, and portable sensors. It performs reliably in extreme conditions from -20°C to 60°C, making it suitable for outdoor, industrial, and professional applications.
Automatic LIR16340 Cells Production Line
In a clean, dust‑free modern workshop with controlled humidity and precision environmental systems, multiple automatic LIR16340 cell production lines operate 24 hours a day to boost production capacity and energy efficiency. As a widely recognized standard size, all core materials used in the production process — including electrodes, separators, and electrolytes for 3.7 V lithium‑ion 16340 cells — are mature and stable to ensure the highest levels of reliability, performance, and safety throughout the manufacturing process.
