What this battery is and who needs it

This DUSLAN 14430 LiFePO4 cell delivers 3.2 Volt nominal voltage and 400 mAh capacity in a 4/5 AA form factor measuring 43.5 mm by 14 mm. It suits devices that specify a 14430 lithium phosphate power source and benefit from up to 2000 charge cycles with no memory effect.

Who it suits and who should look elsewhere

Builders replacing 500 mAh, 350 mAh, 300 mAh or 250 mAh cells in compatible equipment will find this a direct fit. Buyers whose device requires a full AA length, a different chemistry or a voltage other than 3.2 Volt cannot use this battery.

Installation ease and common pitfalls

The cell slides into a standard 14430 holder; observe polarity and never exceed the 0.4 A charge or 0.8 A discharge limits. The most frequent error is confusing the shorter 14430 size with a full AA, so verify the 14430 marking on the old cell before ordering.

Questions about this item

What charger do I need for this 3.2 Volt LiFePO4 14430 cell?

Use a charger made for 3.2 Volt LiFePO4 chemistry with a maximum charge current of 0.4A.

Can I mix this 400 mAh 14430 cell with my older 350 mAh or 500 mAh 14430 cells in the same device?

No. Different capacities cause uneven charge and discharge, which can damage the cells and the device.

How can I confirm the 14430 battery is working correctly after I install it?

Measure the voltage; a healthy cell reads around 3.2 Volt and the device should run for the expected time.
