  • Up to 2000 charge cycles extend service life
  • 2 V 800 mAh LiFePO4 chemistry gives stable voltage
  • Replaces 1000 mAh, 900 mAh, 850 mAh, 750 mAh, 600 mAh cells
  • No memory effect simplifies charging routine
  • Four batteries weigh only 1.1 oz each for light weight

DUSLAN 18500 3.2 V LiFePO4 4-Pack

These four 18500 cells deliver a nominal 3.2 Volt output with an 800 mAh capacity. They suit devices that require this specific size and lithium phosphate chemistry. The pack replaces older cells rated from 600 mAh up to 1000 mAh. Users needing a direct drop-in for compatible equipment will find them appropriate.

Build, connectors and daily use

Each cell measures 50 mm in length and 18.1 mm in diameter, weighing 31.2 g. The standard cylindrical format fits existing battery compartments without adapters. A maximum charge and discharge current of .8 Amp supports steady, moderate loads. Light weight and high energy density of 82.05 wh/kg keep portable devices easy to handle.

Upgrade path and when it matters

The lithium phosphate chemistry eliminates memory effect and provides long storage life. Rated for up to 2000 charge cycles, these cells outlast many older rechargeable types. The jump is worth it when replacing lower-capacity or shorter-lived batteries in compatible 18500 devices. Buyers who need a different voltage, size or higher current rating should look elsewhere.

Questions about this item

What maximum charging current does the 3.2 V LiFePO4 chemistry support?

The cells accept a maximum charging current of 0.8 Amp, matching their 800 mAh capacity for a 1 C rate.

Will the 18.1 mm diameter and 50 mm length fit my device's battery compartment?

Each cell measures 18.1 mm in diameter and 50 mm long, so verify those dimensions against your compartment before ordering.

How do I correctly install the four cells for the first charge cycle?

Insert each cell observing the marked polarity, then charge at or below 0.8 Amp per cell; the common mistake is reversing one cell in a series string.
