Compatible Battery Pack

This set includes four lithium-ion batteries and an LCD triple USB charger designed for Panasonic cordless handsets such as the KX-TCA285, KX-TCA385 and KX-UDT121. Each cell delivers 1400mAh at 3.7V for a total of 5.18Wh. The kit replaces Panasonic part numbers N4FUYYYY0018, N4FUYYYY0019, N4FUYYYY0046 and N4FUYYYY0047.

USB Charging Limits

The charger accepts 5V 2A input through a Micro USB cable and can power three batteries simultaneously at 4.2V 0.5A each. A computer USB port or standard wall adapter supplies the required 10W. The LCD panel shows individual charging status and remaining capacity for every slot.

Capacity and Headroom

Four 1400mAh packs give enough talk time for daily office use on supported DECT models including the Attune II HD3 and WX series handsets. Heavy users who need continuous operation beyond a single shift should keep spare cells charged because the charger only handles three at once.

Questions about this item

Should I choose the four-battery pack or a different capacity?

The pack includes four 1400 mAh lithium-ion batteries and a charger that powers three at once, so you get spare cells without buying extras.

What does the 1400 mAh rating deliver in my handset?

Each cell stores 5.18 Wh at 3.7 V, giving typical talk and standby time for the listed Panasonic DECT models.

How does the micro-USB input limit charging speed?

The charger draws 5 V 2 A (10 W) and outputs 4.2 V 0.5 A per slot, so three batteries charge simultaneously at that fixed rate.
