Replacement for Cordless Handsets

The Estry STB103 is a 3.6V 700mAh nickel-metal hydride pack built to match the original specifications of compatible Panasonic and VTech cordless phones. It supplies 2.52Wh of energy in a 47.0 x 32.0 x 11.5mm form factor weighing 63.0g. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits.

Direct Swap for OEM Packs

This unit replaces part numbers HHR-P103A, HHR-P103, N4HHGMB00001, N4HHGMN00001, N4HHGMB00005 and TYPE 25 across models including STB103, TG272, KX-TGA273, KX-TG2352S, KXTGA271A, KXTGA271, KX-TD7680, KX-TG2352B, KX-TG2383B and KX-GA271W. The jump is worth it when the original pack no longer holds a full day of standby or talk time. Buyers who need a different voltage, a higher capacity or a lithium chemistry will not be served by this pack.

Steady Output Over Repeated Cycles

Nickel-metal hydride chemistry delivers a stable 3.6V through daily charge and discharge cycles rather than a short burst peak. The protection circuit maintains safe limits during prolonged handset use and overnight charging. Capacity remains consistent across the 1 year battery pack rating when the handset is returned to its cradle regularly. Users who leave the phone off-hook for extended periods will see faster depletion.

Questions about this item

Will the 47.0 x 32.0 x 11.5 mm pack fit my handset battery compartment?

The pack measures 47.0 by 32.0 by 11.5 mm and weighs 63.0 g; compare those dimensions with the compartment before ordering.

How do I install the replacement and what step is often missed?

Open the battery cover, disconnect the old connector, attach the new pack matching the polarity, close the cover, then place the handset on its base for a full initial charge.

When will the 700 mAh Ni-MH pack need replacing?

Typical cordless-phone use gives one to two years; replace when talk time drops noticeably or the handset loses charge quickly.
