Compatible replacement for Altec Lansing iMW577

This Cameron Sino battery replaces the original INR18650-2S pack in Altec Lansing iMW577 and iMW577-AB speakers. It delivers 5200mAh capacity at 3.7V for restored portable runtime. The pack is built to the same physical and electrical specifications as the factory unit.

Lithium-ion pack with built-in protection circuit

The 66.20 x 37.10 x 19.10 mm lithium-ion cell weighs 94.2g and fits the existing battery compartment without modification. Integrated safeguards guard against overcharge, over-discharge, over-voltage and short circuits. A fully decoded chip communicates with the speaker electronics exactly like the original battery.

Upgrade from a depleted or swollen original cell

Owners whose speaker no longer holds a charge or shows physical swelling can swap in this new pack and regain full battery life. The replacement is worthwhile when the device otherwise functions but runtime has dropped below usable levels. It is not suited for speakers that use a different form factor or voltage.
