Two-pack Li-ion batteries for Panasonic DECT

This set includes two 1400 mAh 3.7 V lithium-ion cells and a dual-slot USB charger. It fits Panasonic handsets such as the KX-TCA285, KX-TCA385, KX-UDT121, KX-UDT131, Attune II HD3, WX-CH455, WX-SB100, WX-ST100 and WX-ST300. The pack replaces Panasonic part numbers N4FUYYYY0018, N4FUYYYY0019, N4FUYYYY0046 and N4FUYYYY0047.

Charger runs from any 5 V USB source with LCD status

The LTD2 charger accepts Micro-USB or USB-C input at 5 V 2–3 A up to 15 W and charges one or two batteries simultaneously at 4.2 V 800 mA per slot. An LCD panel shows real-time charging state and remaining capacity for each cell. No fan or active cooling is used, so operation stays silent.

Interchangeable plates

The charger ships with a Micro-USB cable and supports swappable contact plates to accommodate other battery models. Two batteries can be powered at once, reducing downtime for multi-handset environments. Buyers needing more than two spare cells or a desktop cradle will need additional accessories.
