Exact Replacement for Versatis and Biloba Phones

This Estry nickel-metal-hydride cell matches the original 3.6V 300mAh specification for the Versatis D100 duo, Biloba 490 and Biloba 590. It replaces part numbers 37AAAM3BMJ, 30AAAM3BMJ and 3BN66090AAAC. The pack delivers 1.08Wh and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Dimensions are 30.0 by 32.0 by 10.5mm at 45.0g.

Simple Two-Wire Swap with Polarity Check

Installation is a straightforward two-wire replacement inside the handset; no soldering is required if the original connector is reused. The main risk is reversing the polarity, which triggers the built-in over-voltage and short-circuit protection and prevents charging. Verify the red and black leads match the device markings before seating the pack. A first charge of several hours calibrates the protection circuit.

Confirm Model and Part Number Before Ordering

Check the label on your existing battery for the exact model name — Versatis D100 duo, Biloba 490 or Biloba 590 — and one of the three listed part numbers. Ensure the handset battery compartment accepts the 30.0 by 32.0 by 10.5mm footprint. This cell is not suitable for devices requiring a different voltage, capacity or connector layout.
