Rechargeable lithium-ion battery XCell 18650 3400 mAh, model 148105

The XCell 18650 3400 mAh is a rechargeable lithium‑ion cylindrical cell designed for devices that accept 18650-format batteries. With a nominal capacity of 3400 mAh, the cell is intended to deliver extended runtime in high-capacity applications while maintaining a compact cylindrical form factor compatible with standard 18650 battery holders and packs. The cell is suitable for single-cell replacements or integration into multi-cell assemblies when appropriate battery management and balancing are used.

Advantages

The XCell 18650 3400 mAh offers a relatively high nominal capacity for its size, providing longer operating times compared with lower-capacity 18650 cells. Its lithium‑ion chemistry provides a favorable energy-to-weight ratio and low self-discharge compared to older rechargeable chemistries. The standard 18650 format ensures compatibility with many flashlights, power banks, portable electronics and custom battery packs when correct polarity and mechanical fit are observed.

Подходит для

• Фонарей и налобных фонарей
• Портативных зарядных устройств и пауэрбанков
• Переносной электроники (радио, беспроводные устройства, модули питания)
• Сборки аккумуляторных блоков и DIY-проектов с 18650

Key specifications

• Cell type: cylindrical lithium‑ion (18650 format)
• Nominal capacity: 3400 mAh
• Nominal voltage: 3.6–3.7 V (typical for lithium‑ion cells)
• Typical form factor: 18 mm diameter × 65 mm length (industry standard 18650 dimensions)
• Recommended charging: charge with a suitable lithium‑ion charger following manufacturer charging current and cutoff voltage
• Intended use: single-cell replacement or multi-cell assemblies with appropriate BMS/charging control

How to use

Install the XCell 18650 3400 mAh with correct polarity in the device or battery holder. For single-cell devices, ensure the positive and negative terminals align with the device contacts. For multi-cell packs, assemble cells with proper orientation, mechanical spacing and insulated connections, and include a battery management system (BMS) or balancing circuit where required. Charge the cell using a charger designed for lithium‑ion batteries, observe the recommended charging current and terminate charge at the specified cutoff voltage. Do not attempt to charge with uncontrolled power sources or chargers for other chemistries.

Рекомендации по использованию

Use the cell within the device manufacturer's specified temperature and current limits, avoid deep discharge below the device cutoff, and store partially charged (around 40–60%) if not used for extended periods. Do not expose the cell to mechanical damage, short-circuiting, high temperature, or water. Replace cells in multi-cell packs with matched capacity and age to maintain pack balance.
