Replacement battery for LG Watch Urbane

This replacement cell fits the LG W150 Watch Urbane and matches the original BL-S3 part number. It uses lithium chemistry at 3.8V with a 300mAh rating.

Who should buy this

Owners of a W150 Watch Urbane needing a direct swap for a worn or dead BL-S3 cell will find the correct fit and voltage here. Buyers who want more capacity than 300mAh or a different form factor should look at other options. The unit carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety and quality assurance.

Key specification: 300mAh capacity

The 300mAh capacity at 3.8V determines how long the watch runs between charges. Verify that your device requires this exact capacity and the BL-S3 part number before ordering. Physical dimensions of 30.9 x 27.5 x 6.5mm must also match the battery compartment.

Questions about this item

How do I install the Estry W150 battery and which step do people get wrong?

Remove the watch back, disconnect the old BL-S3 pack, and connect the new 3.8 V 300 mAh lithium cell; the step often missed is reseating the waterproof gasket so the seal stays intact.

What maintenance or replacement will the Estry W150 battery need later?

The lithium cell has no user-serviceable parts; plan to replace the entire pack once runtime drops noticeably, typically after several hundred charge cycles.

What limit appears first on the Estry W150 battery during sustained use?

The 300 mAh capacity and 1.52 Wh energy limit determine maximum runtime; continuous draw will hit that capacity ceiling before voltage or thermal limits are reached.
