DUSLAN 3.2V 600 mAh LiFePO4 14500 AA standard battery

SKU CH-17K6-5T9T6

3.2 V LiFePO4 AA cell delivering 600 mAh, 14500 size, up to 1000 charge cycles

  • 2 V nominal voltage suits LiFePO4 devices
  • 600 mAh capacity replaces 500 mAh, 400 mAh and lower cells
  • Up to 1000 charge cycles extend service life
  • 14 mm diameter by 50 mm length fits standard AA slots
  • 8 g weight keeps portable equipment light

AA 14500 LiFePO4 cell

This 3.2 volt lithium phosphate battery fits the standard AA 14500 form factor and delivers 600 mAh capacity. It is built for devices that specifically require the higher 3.2 volt nominal voltage rather than the common 1.5 volt alkaline cell. The chemistry provides up to 1000 charge cycles with no memory effect and a long storage life.

Build fit and electrical needs

The cell measures 50 mm in length and 14 mm in diameter, matching the AA 14500 or 14505 size exactly. It supports a maximum charging current of 0.6A and a maximum discharging current of 0.6A. A charger designed for LiFePO4 chemistry at 3.2 volts is required; standard NiMH or Li-ion chargers will not suit this voltage profile.

Replaces lower-capacity 3.2V cells

This unit replaces 3.2 volt AA-size batteries rated at 200 mAh, 250 mAh, 400 mAh or 500 mAh, extending runtime in compatible equipment. It also covers replacements up to 800 mAh within the same voltage and form factor. The jump is worth it when the device manual confirms 3.2 volt LiFePO4 operation and the original cell is marked 14500 or 14505.

Highlights

  • 2 V nominal voltage suits LiFePO4 devices
  • 600 mAh capacity replaces 500 mAh, 400 mAh and lower cells
  • Up to 1000 charge cycles extend service life
  • 14 mm diameter by 50 mm length fits standard AA slots
  • 8 g weight keeps portable equipment light

Questions about this item

What is the maximum continuous discharge current this 600 mAh LiFePO4 cell can sustain?

The cell is rated for a maximum discharging current of 0.6 A, which equals a 1 C rate for the 600 mAh capacity.

How much heat does the 14500 cell generate during prolonged operation at its 0.6 A limit?

At the 0.6 A maximum discharge the internal resistance of LiFePO4 chemistry keeps temperature rise modest; the 19.8 g cell dissipates only a few hundred milliwatts.

What charger specification is needed to recharge this 3.2 V LiFePO4 AA cell?

Use a LiFePO4-compatible charger that delivers up to 0.6 A charge current and terminates at the correct LiFePO4 voltage for a single 3.2 V cell.
