Users with a compatible Pioneer cordless phone

This cell suits owners of Pioneer handsets that accept the TF-BT22 or TF-BT20 part numbers. Buyers who need a different voltage, capacity or form factor should look at something else because this pack is sized and rated for those specific models only.

Simple two-wire connector swap

Installation consists of opening the handset battery compartment, unplugging the old pack and connecting the new one using the existing polarity. The most common issue is reversed wires if the connector is forced; verify orientation before seating the pack.
