Rechargeable lithium-ion battery Samsung 18650 INR18650-35E 3500mAh 3.7V

Samsung INR18650-35E is a rechargeable lithium‑ion cell in 18650 format with a nominal voltage of 3.7 V and a typical capacity of 3500 mAh (minimum 3350 mAh). The cylindrical cell measures approximately 18.5 x 65.3 mm and weighs about 50 g. It is intended as a high‑capacity energy source for devices that accept 18650 cells and provide external protection circuitry.

Advantages

The cell provides high energy capacity for extended runtime and stable discharge performance suitable for steady‑draw applications. It supports pulse discharge currents up to 13 A and continuous discharge currents up to 8 A. Its 18650 size is widely compatible with many portable electronics when used with appropriate protection.

Suitable for

• Flashlights and headlamps
• Power banks and portable power packs (with proper battery management)
• Vape devices and regulated mods that accept 18650 cells
• Portable electronics and DIY battery packs with PCM/PCB/BMS protection

How to use

Install the cell only in devices or packs that include an appropriate protection circuit (PCM/PCB/BMS). Use chargers designed for Li‑Ion cells and follow the charger manufacturer’s instructions. Do not reverse polarity when inserting the cell. Always use protective sleeves or holders when storing or transporting loose cells. Do not solder directly to the cell; use proper battery connectors or spot‑welding in pack assembly.

Usage recommendations

Cells are sold without built‑in electronic protection. The buyer is responsible for using these cells only with devices or battery packs that provide proper overcharge, overdischarge and short‑circuit protection. Follow the manufacturer’s datasheet parameters, avoid mechanical damage, keep cells away from water and high temperatures, do not leave cells in a charger for more than 12 hours, and recycle spent cells according to local regulations.
