Cameron Sino Battery for Altec Lansing iMW577

This replacement battery fits the Altec Lansing iMW577 and iMW577-AB speaker models using part number INR18650-2S. It is a lithium-ion pack rated at 5200mAh and 3.7V with 19.24Wh energy. The unit measures 66.20 x 37.10 x 19.10mm and weighs 94.2g. A decoded chip ensures compatibility with the original device electronics.

Ideal for owners restoring a compatible Altec

Buyers who need a different voltage, capacity or physical size should look elsewhere. The pack is designed for indoor speaker use and is not suited for high-drain power-tool or vehicle applications. Users without access to installation guides or basic repair tools may find the replacement difficult.

Capacity of 5200mAh at 3.7V decides runtime

This single figure determines how long the speaker plays between charges. Match the original 5200mAh rating to maintain expected performance; a lower or higher capacity cell will change the run time and may not fit the battery compartment.

Questions about this item

What speaker models must I own for this 5200 mAh 3.7 V battery to fit?

It is built for the Altec Lansing iMW577 and iMW577-AB speakers using part number INR18650-2S.

Will the replacement cell work with the original charging circuit in my iMW577?

The fully decoded chip behaves like the original pack, so the speaker’s existing charger manages it normally.

How can I confirm the battery is performing correctly after installation?

After two or three full charge and discharge cycles the speaker should reach its normal run-time and the battery gauge will read accurately.
