Compatible replacement for Megaboom 3

This lithium-ion battery replaces the original power cell in Ultimate Ears Megaboom 3 and Megablast speakers. It matches the 3400mAh capacity and 7.4V voltage specified for part numbers 084-000845 and 984-001362. The pack dimensions are 78.40 x 40.40 x 19.00mm and it weighs 102.0g. A decoded chip provides the same communication as the factory unit.

Steady output through a full cycle

The 25.16Wh energy rating supports extended playback at typical listening volumes without the voltage sag seen in lower-capacity cells. Internal protection guards against overcharge, over-discharge, over-voltage and short circuits during continuous use. Performance stabilises after two or three complete charge and discharge cycles as noted by the manufacturer.

Low heat and silent operation

Lithium-ion chemistry generates minimal heat during normal speaker operation, keeping the enclosure close to ambient temperature. There are no moving parts, so the replacement adds no audible noise. The pack draws power only when the speaker is active and enters a low-self-discharge state when idle, preserving stored energy between uses.
