Cylindrical 14500 lithium-ion cell with flat terminals, 14 mm diameter, 50 mm length, metallic finish

DUSLAN

DUSLAN 3.7V 14500 Li-Ion Battery 750 mAh

SKU CH-ETAB-0KF5E

A 3.7 V lithium-ion 14500 cell delivering 750 mAh with a 1.9 A maximum discharge, sized like an AA battery but at triple the voltage

  • Battery typeAA
  • Higher voltage than alkaline AA cells at 3.7 V nominal
  • 750 mAh capacity in standard 14500 form factor
  • 9 A max discharge current supports high-drain applications
  • Light 22.6 g weight with high energy density
  • No memory effect simplifies charging and storage

3.7 V Li-Ion cell for custom packs

This DUSLAN 14500 lithium-ion battery delivers a nominal 3.7 V and 750 mAh capacity in the familiar AA form factor. It is intended for builders assembling custom battery packs who understand lithium-ion charging requirements. The flat terminals on both ends simplify series or parallel connections. This product is not a drop-in replacement for standard alkaline or NiMH AA cells.

3.7 V nominal voltage decides compatibility

The single specification that determines whether this cell suits your project is its 3.7 V nominal output, which is roughly three times higher than a standard AA battery. Devices designed for 1.5 V primaries or 1.2 V rechargeables will be damaged if powered by this voltage. Only use it in circuits explicitly rated for 3.7 V lithium-ion chemistry.

Safety notes and skill requirement change the user

The supplier stresses that improper charging or discharging can cause explosion and requires users to have prior knowledge of lithium-ion pack assembly. No charger, protection circuit, or holder is bundled, so the buyer must source appropriate charging equipment rated for 0.75 A maximum current and integrate suitable protection. This shifts the product from a consumer cell to a component for experienced hobbyists or engineers.

Questions about this item

What does the 3.7 V nominal voltage mean when this cell is installed in a device?

The cell delivers 3.7 V instead of the 1.5 V of a standard AA alkaline, so it cannot be used as a drop-in replacement and is intended only for custom pack designs.

How does the flat-terminal interface limit the charging and discharging rates?

The flat terminals support a maximum charge current of 0.75 A and a maximum discharge current of 1.9 A as specified for this chemistry.

Will the 14 mm diameter and 50 mm length fit a standard AA battery holder?

Yes, the cell matches the 14500 form factor — 14 mm diameter and 50 mm length — so it fits AA holders, but the higher voltage makes it unsuitable for ordinary AA devices.
