Six cylindrical 10440 lithium-ion cells with solder tabs, silver finish, packed in a row

DUSLAN

DUSLAN 6-Pack 10440 3.7 V 350 mAh tabbed standard batteries

SKU CH-K06Q-N9CEV

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

  • Battery TypeAAA
  • 7 V lithium-ion chemistry delivers higher voltage than alkaline AAA cells
  • 350 mAh capacity powers compact devices through extended use
  • Pre-soldered tabs on both ends enable direct pack assembly without spot welding
  • 10440 form factor fits standard AAA slots while providing triple the nominal voltage
  • 6-cell pack supplies multiple spares or series/parallel configurations for custom builds

Six-pack 10440 lithium-ion cells

This set contains six DUSLAN 10440 batteries rated at 3.7 V with 350 mAh capacity. Each cell uses lithium-ion chemistry and carries tabs on both ends for soldered connections. They share the physical length of 43 mm and diameter of 10 mm found in standard AAA sizes. The pack weighs 17 g per cell and is sold new.

For experienced pack builders only

These cells suit hobbyists assembling custom battery packs who understand lithium-ion charge and discharge limits. The maximum charging and discharging current is 0.35 A, so they are not for high-drain devices or direct replacement in consumer electronics expecting 1.5 V AAA alkalines. Buyers who need a simple drop-in AAA alternative should look elsewhere.

Verify voltage and charging gear first

Confirm your equipment accepts 3.7 V nominal input before ordering. A dedicated lithium-ion charger capable of 0.35 A charge current is required. Check that your pack design provides proper insulation and current limiting. Ensure you have the tools and knowledge to spot-weld or solder the tabbed terminals safely.

Questions about this item

What charger do I need for the 3.7 V 10440 lithium-ion cells?

Use a charger made for 3.7 V lithium-ion 10440 batteries with a maximum charge current of 0.35 A.

Can I mix these 3.7 V 10440 tabs with standard 1.5 V AAA alkalines in the same device?

No — each cell delivers 3.7 V, so mixing with 1.5 V alkalines would over-volt the device.

How can I verify the 350 mAh capacity after the first charge cycle?

Discharge at 0.35 A and measure delivered capacity; a healthy cell should yield close to 350 mAh.
