Replacement Battery for Altec Lansing iMW577

This 3.70V lithium-ion cell replaces the original INR18650-2S pack inside the Altec Lansing iMW577 and iMW577-AB portable speakers. It restores full runtime for owners whose factory battery no longer holds a charge. The 5200mAh capacity matches the OEM specification for direct compatibility.

Drop-in fit for the speaker chassis

The pack slides into the existing battery compartment without modification to wiring or enclosure. No external charger or adapter is required because the speaker manages charging through its standard power input. Swapping the cell frees the speaker from mains dependence for outdoor or travel use.

Sustained output for long listening sessions

The 19.24Wh lithium-ion chemistry delivers steady current throughout the discharge cycle rather than fading after a short burst. Built-in protection circuitry guards against over-charge, over-discharge and short circuits during extended play. Capacity remains stable across repeated charge cycles in normal speaker operation.
