Direct Replacement for STB124 and 2102 Devices

This Estry battery is a direct replacement for equipment that uses the STB124 or 2102 part numbers. It supplies the original 3.6V and 600mAh rating in a Ni-MH chemistry pack. The physical envelope measures 42.64 x 30.0 x 14.45mm and weighs 63.3g, matching the factory footprint. Buyers who need a different voltage, chemistry or form factor cannot use this cell.

Capacity and Runtime Limits

The pack stores 2.16Wh of energy, which suits low-drain applications such as cordless phones, emergency lights or backup modules. At 600mAh it will not sustain high-current loads or extended runtimes without recharging. Users expecting all-day operation from a single charge or rapid discharge capability should look elsewhere.

Certified Safety and Compliance

The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming regulated manufacturing and transport safety. Over-charge, over-discharge, over-voltage and short-circuit protection circuits are integrated. Installers who require unprotected raw cells or non-certified packs must choose a different product.

Questions about this item

Will this 3.6 V 600 mAh pack run in the same device that currently uses a STB124 2102 cell?

Yes, the pack is built to the original STB124 2102 specifications so it drops straight into any device that took that part number.

How can I verify the 3.6 V 600 mAh pack is working correctly after I install it?

Charge the pack fully, then check that your equipment shows the expected voltage and runs for the normal operating time.

What comes in the box and do I need to buy anything else to use it?

The box contains the single 42.64 x 30.0 x 14.45 mm, 63.3 g battery; no charger or cables are included, so use the device’s own charging circuit.
