Drop-in power for UE Boom 3

This Cameron & Co DS-CS-LOE984SL Li-ion cell replaces the original 3.7V 2600mAh battery inside the Logitech Ultimate Ears Boom 3 speaker. It matches the OEM part numbers 984-001405, S-00170 and T123682016VK. The 2.6Ah capacity restores factory runtime for portable listening. Black housing matches the speaker interior.

Fits the original cavity without modification

The cell measures 66.80 x 21.00 x 18.50 mm, matching the stock battery footprint exactly. No adapter brackets, soldering or cable extensions are required. It frees the speaker from a depleted pack that no longer holds charge. Installation is a direct swap using the existing connector.

Steady output through a full playlist

Li-ion chemistry delivers consistent 3.7V nominal voltage across the discharge curve rather than a sharp drop-off. The 9.62Wh rating supports extended playback at moderate volume without voltage sag. Capacity remains stable over repeated charge cycles. Not suited for devices requiring higher voltage or different form factors.

Questions about this item

How long does the 2600 mAh capacity last before the 3.7 V Li-ion cell needs recharging under continuous speaker use?

The 2.6 Ah cell stores 9.62 Wh, so run-time depends entirely on the speaker's power draw; at 1 W it would last about nine and a half hours.

Does the battery generate noticeable heat or noise when powering the Ultimate Ears Boom 3 for a full day?

Li-ion chemistry runs silently and produces only modest warmth during normal discharge; no fan or moving parts are present.

What must I already own to install this 66.80 x 21.00 x 18.50 mm replacement in my speaker?

A compatible Ultimate Ears Boom 3 (part numbers 984-001405 or S-00170) and basic tools to open the enclosure.
