Eight cylindrical 14430 LiFePO4 cells in light wrapping, each 43.5 mm long and 14 mm wide

DUSLAN

DUSLAN 3.2V 14430 LiFePO4 400mAh 8-Pack standard battery

SKU CH-YPEP-DJM4Q

Eight 3.2 V 14430 LiFePO4 cells deliver 400 mAh each, up to 2000 cycles, and fit devices needing 4/5 AA size

  • 8-pack delivers reliable power for compatible devices
  • 2 V nominal voltage matches equipment specifications
  • 400 mAh capacity replaces cells rated from 200 mAh to 600 mAh
  • LiFePO4 chemistry provides up to 2000 charge cycles with no memory effect
  • Compact 14430 size at 43.5 mm length and 14 mm diameter fits tight spaces

3.2V 14430 LiFePO4 pack

This pack contains eight 14430 lithium iron phosphate cells rated at 3.2 volts and 400 milliampere-hours each. They are built for devices that need a stable 3.2 volt supply in the smaller 4/5 AA form factor. The chemistry delivers up to 2000 charge cycles with no memory effect and a long storage life. Buyers who need a higher voltage per cell or a standard AA length will not be served by this size.

Capacity and discharge headroom

Each cell stores 400 mAh and can supply a maximum discharge current of 0.8 amps for short bursts. Continuous loads at or below 0.4 amps are well within the comfort zone and the 75.29 watt-hours per kilogram energy density keeps weight low at 17 grams per cell. Applications that regularly draw more than 0.8 amps or require capacities above 600 mAh will exhaust these cells quickly.

Replaces legacy 14430 sizes

The 400 mAh rating directly replaces older 14430 cells marked 250, 300, 350 or 500 mAh, and the supplier notes compatibility with any 14430 labelled between 200 and 600 mAh. The jump is worth it when the original pack has degraded after fewer cycles or when the lighter 17 gram mass and higher cycle count reduce replacement frequency. Devices that demand a larger physical cell such as full AA or that need a different chemistry cannot use this pack.

Questions about this item

Will these 3.2V 14430 LiFePO4 cells fit the 4/5 AA slots in my older solar lights?

Each cell measures 43.5 mm long and 14 mm in diameter, matching the 4/5 AA form factor; verify the 14430 marking on your existing batteries before swapping.

How can I confirm the pack is delivering the rated 400 mAh after the first charge?

Charge at up to 0.4 A, then discharge at 0.8 A while timing the run; reaching roughly the rated capacity shows the cells are working as intended.

What comes in the 8-pack and do I need a separate charger?

The box contains eight 3.2 V 400 mAh 14430 LiFePO4 batteries; a compatible LiFePO4 charger is not included and must be sourced separately.
