Replacement for Goldstar Cordless Phones

This Estry 20X Ni-MH battery replaces the original Goldstar pack in models such as the 20X, 220CT and GP60AAH3BMJ. It delivers 3.6 volts and 600mAh capacity in a single-cell pack. The unit is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards for safe operation.

Drop-in fit with built-in protection

The pack measures 42.57 by 30.2 by 14.43 millimetres and weighs 77.4 grams, matching the original footprint so no adapter or wiring changes are needed. Integrated over-charge, over-discharge, over-voltage and short-circuit protection guards the cells and the handset circuitry during every charge cycle.

Talk-time headroom for daily use

At 2.16 watt-hours the cell powers typical circa-2000 cordless handsets through extended calls and standby periods. Heavy users who need multiple days of talk time between charges will find the 600mAh limit restrictive and should consider a higher-capacity pack if the handset bay allows it.
