Twelve cylindrical lithium-ion cells with solder tabs on both ends

DUSLAN

DUSLAN 12-Pack AAA 3.7V 10440 Li-Ion 350 mAh Tabbed

SKU CH-2Y7B-H0MQZ

Twelve 3.7 V 10440 lithium-ion cells with solder tabs, 350 mAh each, for custom battery packs

  • Battery TypeAAA
  • 12 cells deliver reliable 3.7 V power for custom builds
  • 350 mAh capacity supports extended run-time per charge
  • 10 mm diameter fits standard AAA compartments
  • Tabbed terminals enable direct soldering to PCBs
  • Lithium-ion chemistry provides lightweight 17 g energy density

12-Pack 3.7 V 10440 Lithium-Ion Cells

This pack supplies twelve AAA-size lithium-ion cells rated at 3.7 volts and 350 mAh each. They are intended for hobbyists, technicians and engineers who build custom packs or repair devices that require tabbed terminals. The cells arrive new and ready for soldering into battery assemblies.

350 mAh capacity with 0.35 A continuous limits

Each cell delivers 350 mAh, providing enough energy for low-drain electronics such as LED torches, sensors or small telemetry modules. The maximum continuous charge and discharge current is 0.35 A, so the cells cannot sustain high-power loads like motors or bright lamp arrays without voltage sag or overheating.

Tabbed terminals on both ends

Every cell carries spot-weld tabs on the positive and negative ends, allowing direct series or parallel connections without soldering to the bare can. Buyers who need bare button-top or flat-top cells for spring-loaded holders cannot use these tabs without removal.

Questions about this item

Will the 3.7 V 10440 cells damage a device designed for 1.5 V AAA alkalines?

These cells deliver 3.7 V nominal, three times the voltage of standard AAA alkalines, so they must only be used in equipment that explicitly accepts 3.7 V lithium-ion chemistry.

How can I confirm the 350 mAh capacity is genuine after the first charge cycle?

Charge at or below 0.35 A, then discharge at 0.35 A to the device cut-off; a healthy cell will deliver roughly 350 mAh.

The pack lists tabs on both ends — are holders or soldering gear included?

Only the 12 tabbed 10440 cells are supplied; tab-compatible holders or soldering equipment must be purchased separately.
