What this kit replaces

The Kastar PS-42B pack supplies four lithium-ion batteries and one AC wall charger for Panasonic DECT handsets. It covers part numbers N4FUYYYY0018, N4FUYYYY0019, N4FUYYYY0046 and N4FUYYYY0047. The bundle suits offices or homes that run multiple compatible handsets and want a single charging station.

Capacity and voltage match

Each cell delivers 3.7 V and 1400 mAh, giving 5.18 Wh of energy. The charger accepts 100–240 V at 50–60 Hz and outputs 4.2 V at 600 mA. A red LED shows charging, while green signals standby or full charge. These figures must match the original handset specifications for safe operation.

Foldable plug keeps the outlet clear

The wall adapter uses a foldable flat pin that lies flush when not in use, leaving the socket free for other devices. No separate dock or base unit is included, so each handset charges directly from the supplied charger. Buyers needing simultaneous multi-bay charging or a desktop cradle should look elsewhere.

Questions about this item

How long will a 1400 mAh 3.7 V battery run a typical DECT handset between charges?

The 5.18 Wh cells match the original Panasonic capacity, so talk and standby times stay the same as the factory pack.

What does the charger’s 4.2 V 600 mA output mean for recharge speed?

Each battery reaches full charge in roughly two to three hours from empty, with the red LED switching to green when done.

Will the foldable flat plug fit a standard UK wall socket without an adapter?

The plug is designed for North American AC 100–240 V outlets; a UK travel adapter is required for British sockets.
