Direct replacement for UE Roll speakers

This Estry WS600 lithium battery replaces the original pack in UE Roll, UE Roll 2, UE Roll Ears Boom and WS600 series speakers. It delivers 2200mAh at 3.7V with 8.14Wh energy capacity. The cell matches factory specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection.

Check model and part number before ordering

Confirm your speaker uses part number 533-000122 or T11715170SWU and that the model is listed as WS600, WS600BL, WS600VI, UE Roll 1, UE Roll 2 or UE Roll Ears Boom. The pack measures 67.03 x 21.52 x 18.5mm and weighs 118.0g so internal space must accommodate those dimensions.

Runs cool with certified safety circuitry

Protection circuits prevent excess heat during charge and discharge cycles. The battery carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for materials and transport safety. Normal use in the supported speakers stays within thermal limits without active cooling.

Questions about this item

Does the Estry WS600 pack include the tools needed to swap the battery in my UE Roll 2?

The pack contains one 3.7V 2200mAh lithium cell weighing 118.0g; installation tools are not included.

Is the 2200mAh version the only capacity offered for the WS600 replacement?

Yes, this replacement is supplied in a single 2200mAh 8.14Wh configuration.

Will the 8.14Wh rating deliver the same runtime as the original 533-000122 cell in my UE ROLL?

The 3.7V 2200mAh 8.14Wh specification matches the original 533-000122 rating, so runtime should be equivalent.
