Direct replacement for Panasonic DECT phones

The Estry KX-TG7433B is a 2.4V 700mAh nickel-metal hydride battery pack built to match the original specifications for a wide range of Panasonic cordless handsets. It suits owners of models such as the KX-TG7433B, KX-TG6434PK, KX-TG6531B and KX-TG9348 who need a fresh power source for daily talk time.

Simple drop-in installation with polarity care

The pack measures 44.23 x 20.57 x 10.3mm and weighs 49.0g, fitting the existing battery compartment without modification. The only common issue is reversing the connector polarity during insertion; align the plug using the keyed shape before pressing it fully home.

Ni-MH chemistry limits runtime and shelf life

The 1.68Wh capacity delivers typical talk and standby periods for DECT handsets but cannot match lithium-ion energy density. Self-discharge will reduce stored charge over weeks of non-use, so handsets left off the base for long periods may need a full recharge cycle before service.
