Estry 80-5543-00-00 standard battery 700mAh 3.6V Ni-MH

Replacement battery for VTech handsets

The Estry 80-5543-00-00 is a direct replacement Ni-MH battery pack rated at 700mAh and 3.6V. It matches the original specifications for VTech models 80-5543-00-00 and 80-5542-00-00. The single-cell pack measures 48.46 x 31.16 x 10.67mm and weighs 58.0g. It is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Simple drop-in installation

The pack slides into the handset battery compartment using the existing connector, so no soldering or tools are required. Verify the part number on your old battery matches 80-5543-00-00 or 80-5542-00-00 before fitting. A mismatch in dimensions or connector polarity will prevent the pack from seating correctly. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Talk-time capacity and limits

The 700mAh capacity restores typical cordless phone talk and standby durations for the listed VTech models. Heavy daily use or weak signal conditions will drain the pack faster, requiring more frequent recharges. The 0.0Wh rating reflects the single-cell Ni-MH chemistry at 3.6V. Users needing extended runtime beyond the original specification should consider a higher-capacity alternative if one exists for their handset.
