Direct replacement

This Estry CS0139 battery replaces the original Tandy pack with identical 3.6V 600mAh Ni-MH chemistry. The 2.16Wh cell is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits for safer operation.

Form factor fit

Measuring 42.57 x 30.2 x 14.43mm and weighing 77.4g, the pack slots into the existing compartment without adapter cables or chassis modifications. The single-cell design frees up space that a multi-cell stick would occupy and requires no external charger beyond the host device.

Steady discharge

Ni-MH chemistry delivers a stable voltage plateau through the 600mAh capacity rather than a brief peak. Protection circuitry maintains safe limits during prolonged use, preventing the voltage sag that can reset sensitive electronics. Not suited for applications needing higher capacity or a different voltage rail.

Questions about this item

How long will the 600mAh capacity last under continuous use before needing a recharge?

The 600mAh rating delivers 2.16Wh of energy; actual runtime depends entirely on the current draw of the device you are powering.

Does the Ni-MH pack generate noticeable heat or require special ventilation during all-day operation?

Normal charging and discharging produces only modest warmth; the built-in over-voltage and short-circuit protection keeps temperatures within safe limits.

What charger or device connector is needed to use this 3.6V replacement pack?

It is a direct replacement for the Tandy CS0139 model, so the original equipment’s charging cradle or connector will mate without adapters.
