Alcatel-Lucent ALE-160 WB Compatible Battery 3.7V 350mAh

Alcatel-Lucent ALE-160 WB / ALE-161 WB — 3.7V Li-Polymer Replacement Battery (3ML37161AA)

This 3.7V, 350mAh Li-Polymer battery replaces the original cell in the Alcatel-Lucent ALE-160 WB and ALE-161 WB DECT cordless handsets. It matches OEM part numbers 3ML37161AA and EN13300. Physical dimensions are 32.00 × 13.50 × 12.60mm — verify these against your existing cell before ordering.

• ALE-160 WB and ALE-161 WB compatibility: Both handsets share the same battery bay dimensions, connector pinout, and 3.7V Li-Polymer chemistry, so one cell covers both models without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the ALE-160 WB platform. The protection circuit held cutoff at the correct low-voltage threshold and accepted charge current from the base station without triggering a fault state.
• First-charge protocol for Li-Polymer cordless handsets: Place the handset in the base immediately after fitting the new cell and leave it undisturbed for a full charge cycle before making any calls. Li-Polymer cells shipped in storage state need one uninterrupted charge to calibrate the handset's fuel gauge accurately.

Talk time shorter than original battery after replacement

A new Li-Polymer cell often delivers less talk time than expected for the first two or three cycles. This happens because the handset's charge controller reads the stored cell as partially depleted and terminates charge early. Run two to three complete charge-then-use cycles and the controller recalibrates to the full 350mAh capacity. If talk time is still short after four cycles, check that the base station contacts are clean and making solid contact with the handset.

Handset loses DECT pairing when battery is swapped

The ALE-160 WB stores its base station pairing in volatile memory backed by the battery. When the cell drops below approximately 3.0V during removal, that memory clears and the handset comes back as an unregistered device. Re-register the handset at the base using the registration button — the process takes under two minutes and restores full call functionality.
