Replacement Battery for UE Boom 2

This 2600mAh lithium cell matches the original 00798-601-8207 specifications for the UE Boom 2 and UE Boom 2 Ultimate speakers. It restores portable playback time when the factory pack no longer holds a charge. Buyers who need a different form factor or a higher capacity for another device should look elsewhere.

Thermal Behaviour and Power Draw

The 3.7V chemistry delivers 9.62Wh of energy inside a 67.6 x 22.6 x 19.0mm housing that weighs 119.0g. Normal speaker operation keeps the pack well within its thermal limits without active cooling. The integrated circuit provides overcharge, over-discharge, over-voltage and short-circuit protection for stable output.

Decisive Specification — 2600mAh Capacity

Capacity determines how long the speaker runs between charges; this unit supplies 2600mAh at 3.7V. Verify that your speaker uses part number 00798-601-8207 before ordering. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Questions about this item

How do I install the Estry 2600mAh 3.7V battery in my UE Boom 2 Ultimate, and what step do people often miss?

Open the speaker casing, disconnect the original 00798-601-8207 pack, then connect the new battery's connector to the same socket — the step many miss is routing the wires so the 67.6 x 22.6 x 19.0 mm pack sits flat before resealing the enclosure.

What maintenance or replacement will this 9.62Wh lithium pack need later?

No routine maintenance is required; the pack includes overcharge, over-discharge, over-voltage and short-circuit protection. Replace it only when run-time drops below your needs — typical lithium life is several hundred full cycles.

What limit appears first during sustained high-volume playback with this 2600mAh cell?

The speaker's thermal protection will throttle output before the battery's 3.7V nominal voltage sags, so sustained loud playback is limited by heat rather than capacity.
