14.6V Sonos Move Compatible Battery 2400mAh 111-00001

Sonos Move / MOVE1US1 — 14.6V Li-ion Replacement Battery (111-00001)

This is a 14.6V, 2400mAh (35.04Wh) Li-ion replacement battery for the Sonos Move portable speaker. It fits the Move and MOVE1US1 variants and restores untethered operation when the original cell has degraded. OEM part numbers 111-00001 and IP-03-6802-001 both apply to this pack.

• Move and MOVE1US1 compatibility: Both variants run the same 14.6V four-cell architecture with an identical BMS handshake, so one pack covers both. The connector and cell configuration are shared across the production run.
• Bench tested on actual hardware: We cycled this pack through charge and full discharge on a Move unit. The BMS communicated state-of-charge correctly to the speaker's firmware, and the fuel gauge tracked accurately across the full voltage range from 16.8V charged down to the cutoff threshold.
• Monthly discharge cycle on the Move: The Move spends most of its life on the charging base — that constant top-off without a full discharge causes fuel gauge drift over time. Run the speaker down below 20% at least once a month before placing it back on the base to keep cell calibration accurate.

Why the Move's audio distorts before the battery indicator reaches empty

As the Li-ion pack discharges toward its lower voltage limit, cell voltage sags under the combined draw of the amplifier and the Wi-Fi or Bluetooth radio. The amplifier receives less voltage than it needs to reproduce the signal cleanly, and it clips — producing audible distortion before the indicator has flagged low battery. This is a voltage-sag symptom, not a speaker fault. A fresh pack with healthy internal resistance eliminates the sag and pushes the distortion threshold well below the low-battery cutoff.

Move won't wake from USB-C after sitting unused for several weeks

A deeply discharged Li-ion pack can fall below the USB-C PD minimum acceptance voltage — typically around 2.5V per cell — and the charger will not initiate a charge session because it cannot negotiate a valid PD contract. The BMS needs a small trickle current to recover to a negotiable voltage, which the Move's charging base handles better than the USB-C port in this state. Place the speaker on the Sonos charging base rather than a USB-C cable, wait 10–15 minutes, then check whether the LED indicator responds before attempting a USB-C charge.
