Questions about this item

What capacity and energy rating does the 400mAh lithium-ion cell provide?

The cell delivers 400mAh at 1.52Wh, matching the original BL-S3 specification for compatible LG watches.

What physical dimensions and weight must the watch compartment accommodate?

The replacement measures 69.70 x 55.36 x 18.62mm and weighs 146.3g, so the battery bay needs at least that volume and support.

How is the battery installed and which step do users most often miss?

Connect the decoded chip connector firmly to the device header before sealing the case; a loose connector is the most common cause of a dead-on-arrival fit.
