ASOL 18650 3.7V 2200mAh Lithium-ion Battery Cell applications

The ASOL INR18650-2200mAh is a compact 18650 rechargeable Li-ion cell for customers who need a stable 3.7V battery platform with 2200mAh rated capacity. It can be supplied as a bare cell or configured for battery pack production with nickel tabs, wire leads, connectors, insulation sleeves and PCM/PCB protection.

This product is suitable for OEM projects where a 2200mAh 18650 cell and 2.2A per-cell discharge rating meet the electrical design. It is a direct fit for flashlights, portable fans, Bluetooth speakers and solar street lights. For battery packs for portable power equipment, low-power cordless tools and compact handheld vacuum cleaners, it should be used as part of a properly engineered multi-cell battery pack with matched cells, a suitable BMS/PCM and current limits confirmed by the device design. ASOL can support sample builds, connector matching, label customization and batch production.

Why Choose 18650 2200mAh Cells?

The 18650 cylindrical cell remains one of the most widely used rechargeable Li-ion formats because it balances cost, supply stability and mechanical durability. The ASOL INR18650-2200mAh is a practical option for products that need a reliable 3.7V cell without oversized capacity or unnecessary pack weight.

  • Standard 18 x 65 mm format — easy to integrate into common holders, enclosures and pack structures.
  • Balanced capacity — 2200mAh / 8.14Wh supports compact runtime-focused devices.
  • Moderate discharge rating — 2.2A per cell is suitable for low-to-medium power loads, or higher-voltage packs designed with enough parallel cells.
  • Flexible pack building — can be used as single cells or assembled into series / parallel battery packs.
  • Custom protection options — PCM/PCB, wire leads, tabs and connectors are available for OEM orders.
  • Stable sourcing — suitable for repeated production batches and replacement programs.
