Blue cylindrical 18500 lithium-ion cell flat terminals 50.3 mm long 18.3 mm diameter 34 g

DUSLAN

DUSLAN 4/3 A 3.7V 18500 Lithium-Ion 1600 mAh standard battery

SKU CH-8R0X-975MG

A 3.7 V 18500 lithium-ion cell delivering 1600 mAh with 1.6 A charge and 2.6 A discharge limits

  • Battery type4/3 A
  • 1600 mAh capacity powers devices longer
  • 7 V nominal voltage suits many electronics
  • 6 A max discharge handles high-drain loads
  • 34 g lightweight cell adds minimal bulk
  • Flat terminals on both ends simplify soldering

Battery type and intended use

This DUSLAN 4/3 A cell is a 3.7 V lithium-ion 18500 battery rated at 1600 mAh. It suits devices designed for the shorter 18500 form factor where a flat-top terminal is required. Builders assembling custom packs or repairing equipment that specifies this exact size and chemistry will find it compatible. It is not for devices that need the longer 18650 cell or a button-top terminal.

Capacity and current limits

The 1600 mAh capacity provides moderate energy storage for low-to-medium drain applications. Maximum charging current is 1.6 A and maximum discharging current is 2.6 A, so the cell handles steady loads within that range. Demands beyond 2.6 A or charging above 1.6 A exceed the rated limits and will cause the cell to run out of safe headroom. The flat terminals on both ends simplify series connections in pack builds.

Physical traits and handling notes

The cylindrical cell measures 50.3 mm in length and 18.3 mm in diameter, weighing 34 g (1.2 oz). Its blue sleeve identifies the brand and the lithium-ion chemistry, which has no memory effect and offers long storage life. Safe operation requires proper charge and discharge knowledge; misuse can lead to venting or explosion. No charger, protection circuit or wiring is included with the bare cell.

Questions about this item

Will this 18500 cell fit in a device designed for an 18650 battery?

The 18500 cell is shorter than an 18650 at 50.3 mm length with the same 18.3 mm diameter, so it will not make proper contact in a standard 18650 holder.

How can I verify the 3.7V 1600 mAh cell is performing correctly after installation?

Measure the open-circuit voltage near 3.7 V and confirm the device draws current smoothly up to the 2.6 A maximum discharge rating without voltage sag or overheating.

Does the flat-top 18500 battery ship with a charger or protective sleeve?

The cell is supplied as a single loose unit with a blue sleeve; a compatible Li-Ion charger and any additional insulation or holder must be purchased separately.
