Batteria ricaricabile agli ioni di litio Samsung ICR1865030K 3000 mAh 3,7 V (18650)

Samsung ICR1865030K is a rechargeable lithium‑ion cell in the 18650 format with a nominal capacity of 3000 mAh and nominal voltage of 3.7 V. The cell is designed for applications that require a compact energy source with consistent discharge characteristics. It is intended for installation in devices and battery packs where standard 18650 cells are used and must be charged with a compatible lithium‑ion charger that monitors voltage and current.

Advantages

The Samsung 18650 cell offers a balance of energy density and cycle life suitable for consumer electronics and portable equipment. Its 3000 mAh nominal capacity provides extended runtime compared with lower‑capacity 18650 variants while maintaining stable voltage during typical discharge. The cell is lightweight and compact, allowing efficient use in confined battery housings and multi‑cell assemblies when cells are matched for capacity and condition.

Suitable for

• Portable electronics such as headlamps, handheld fans, and radios
• High‑capacity power banks and custom battery packs
• Flashlights and tactical lighting applications
• Hobbyist projects, RC devices, and DIY battery assemblies

Key specifications

• Cell format: 18650 (cylindrical lithium‑ion cell)
• Nominal capacity: 3000 mAh
• Nominal voltage: 3.7 V
• Chemistry: lithium‑ion (ICR-type, cobalt‑based cathode)
• Typical use: rechargeable single cell or multi‑cell packs
• Physical form factor: 18 mm diameter × 65 mm length (approximate standard 18650 size)

How to use

Install the cell in the device or holder observing correct polarity and ensuring firm contact with terminals. Charge the cell only with a charger designed for lithium‑ion 18650 cells that provides appropriate constant‑current/constant‑voltage (CC/CV) charging and terminates when the cell reaches the recommended charge voltage. When assembling multi‑cell packs, use matched cells and appropriate battery management or protection circuitry to prevent overcharge, overdischarge, and cell imbalance.

Recommendations

Store cells in a cool, dry place and avoid extended exposure to high temperatures. Do not short‑circuit, puncture, or disassemble the cell. Observe manufacturer and device guidelines for maximum charge and discharge currents; replace cells that show significant capacity loss, swelling, or visible damage. For safe long‑term storage, store at partial state of charge (around 30–50%).
