Compatible Cordless Phone Battery

The Estry 6609 is a 2.4V 700mAh Ni-MH replacement pack built to match the original specifications of supported VTech handsets. It fits models such as the CS6114-11, CS6124, CS63294, CS64192, CS6519 and LS6325-4. The pack measures 44.6 x 20.91 x 10.47mm and weighs 49.5g.

Sustained Talk-Time Performance

The 700mAh capacity delivers a steady 1.68Wh of energy for long conversations and standby periods. Ni-MH chemistry maintains a stable voltage curve under continuous load, avoiding the sharp drop-off seen in short bursts. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits. This design supports reliable daily cycling throughout the one-year service window.

Straightforward Handset Swap

Installation requires opening the battery compartment, disconnecting the old pack and connecting the new one using the existing connector. The pack dimensions match the original casing so no modification is needed. The main risk is ordering the wrong variant; verify the handset model number and the battery part number such as BT1623421 or 8913470100 before purchase.

Questions about this item

How much heat does the 2.4 V 700 mAh Ni-MH pack generate during a full day of talk time?

The pack is rated at 1.68 Wh and uses Ni-MH chemistry, which runs cool under normal cordless-phone loads; no active cooling is required.

What must the buyer already own for this 44.6 × 20.91 × 10.47 mm battery to work?

A compatible VTech cordless handset such as the CS6114-11, CS6124, CS6329-4, CS6419-2, CS6519 or CL81300 that accepts the original BT1623421 or BT262342 pack.

Will this replacement fit the older LS6325-4 and 6529 base stations I still use?

Yes — the 6609 cell matches the voltage, capacity and connector of the original BT1623421 and BT262342 packs used in those models.
