DUSLAN 18500 3.2V LiFePO4 Battery 800mAh

SKU CH-G4JT-XZGQM

A 3.2 V LiFePO4 18500 cell rated at 800 mAh, offering up to 2000 charge cycles with no memory effect and a light 31.2 g design

  • LiFePO4 chemistry delivers stable 3.2 V output
  • 800 mAh capacity replaces cells rated 600–1000 mAh
  • Up to 2000 charge cycles for long service life
  • No memory effect simplifies charging routine
  • Compact 18500 size fits 18.1 mm × 50 mm slots

DUSLAN 18500 LiFePO4 Battery

This 3.2 Volt lithium phosphate cell delivers 800 mAh capacity in the standard 18500 form factor. It suits devices requiring a flat discharge curve and long cycle life. The chemistry avoids memory effect and supports extended storage without significant capacity loss. Builders repairing solar lights, medical equipment or custom packs will find it a direct fit.

3.2 Volt Nominal Voltage

The single specification that decides compatibility is the 3.2 Volt nominal voltage, which differs from common 3.7 Volt lithium-ion cells. Using this cell in a device designed for higher voltage will cause underperformance or failure to operate. Verify the original battery voltage before purchase. This cell replaces capacities from 600 mAh up to 1000 mAh.

Straightforward Solder-Tab Installation

Installation typically requires spot-welding or soldering tabs onto the cylindrical ends, so basic electronics tools and heat management are needed. Excessive heat during attachment can damage the internal separator and reduce the rated 2000 charge cycles. Observe correct polarity and ensure the 50 mm by 18.1 mm dimensions match the battery compartment. No memory effect simplifies maintenance charging.
