Bateria Li-Ion 18650 recarregável Samsung INR18650 30Q 3000mAh 3,6V Flat-Top

Samsung INR18650 30Q is a rechargeable Li‑ion 18650 cell with a nominal capacity of 3000mAh and a nominal voltage of 3.6V in a flat‑top format. Designed for high‑capacity energy storage, this cell offers consistent discharge characteristics and is intended for use in devices that accept flat‑top 18650 cells. The chemistry and construction provide a balance between energy density and cycle life when charged and discharged within recommended limits.

Advantages

The cell delivers a relatively high capacity for its size, providing extended runtime in portable devices. Its flat‑top format simplifies installation in applications that require non‑button top cells. Stable discharge voltage and predictable performance across moderate current draws make it suitable for battery packs and power banks. The rechargeable lithium‑ion chemistry enables multiple charge cycles with appropriate charging equipment and protection.

Suitable for

• Power banks and portable chargers
• High‑capacity flashlights and handheld lighting
• Battery packs for tools, DIY electronics and hobby projects
• Energy storage modules requiring 18650 flat‑top cells

Key specifications

• Cell type: Rechargeable lithium‑ion (Li‑ion), 18650 format
• Nominal capacity: 3000 mAh
• Nominal voltage: 3.6 V
• Cell top: Flat‑top design
• Typical use: Moderate continuous discharge currents; optimized for energy density

How to use

Install the flat‑top 18650 cell into devices or battery holders designed to accept flat‑top cells, ensuring correct polarity. Charge using a compatible lithium‑ion charger or battery management system (BMS) that provides appropriate constant‑current/constant‑voltage (CC/CV) charging and termination at the manufacturer‑recommended voltage. Avoid charging or discharging beyond the device or charger specifications. For pack assembly, use proper cell holders, balancing and a protection circuit to prevent overcharge, overdischarge and short circuits.

Recommendations

Store cells in a cool, dry place and avoid exposure to high temperatures or direct sunlight. Use a charger or BMS designed for lithium‑ion cells, follow recommended charge/discharge limits, and do not use damaged or swollen cells. For safety and longevity, avoid deep discharges and maintain cells within recommended state‑of‑charge ranges when storing for extended periods.
