🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Revitalize your classic LG smartwatch with this BL-S3 410mAh replacement battery. Designed for LG G Watch R (W110, 1.3‑inch P‑OLED round display, $299 debut price), G Watch Urbane (W150, stainless steel body, premium Android Wear experience), and compatible with the original G Watch (W100, may require minor modification). This Li‑Polymer battery delivers factory‑rated 410mAh capacity — restoring full‑day usage for notifications, fitness tracking, and core smartwatch functions. For reference, third‑party retailers sell this battery for approximately $12 to $25.
Built with Grade A Li-Polymer cells and multi‑layer safety protection against overcharge, over‑discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. The watch supports 5V/0.85A (4.25W) charging — charging the G Watch through a USB cable attached to a laptop computer takes the same time as with the original power adapter. With a cycle life of 300‑500 full charge cycles, this replacement battery is designed for long‑term durability.
Compatibility Note: Please power down your watch and check your original battery label before ordering. Ensure the model number printed matches BL-S3. The G Watch (W100) uses a different internal battery connector — verify compatibility before purchasing. Professional installation is recommended as the watch has a sealed case requiring careful opening.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3‑5 full charge cycles to reach optimal capacity. For best charging performance, use the original LG 5V/0.85A charger. If you don’t use the watch for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

Frequently Asked Questions

The BL-S3 battery for LG G Watch R is compatible with LG G Watch R (model W110, 1.3‑inch P‑OLED round display, debuted at $299), LG G Watch Urbane (model W150, stainless steel body), LG G Watch Urbane 2nd Edition LTE, and the original LG G Watch (W100 — please verify your original battery connector before purchasing). The G Watch R and Urbane use the same BL-S3 battery as a drop‑in replacement, but the original G Watch (W100) may have a different internal connector. This BL-S3 replacement battery for LG G Watch Urbane restores the original 410mAh capacity. If your LG G Watch R battery replacement is needed because the watch drains quickly or won't hold a charge, this is the correct BL-S3 battery. Please verify your watch model and check the battery model BL-S3 printed on your existing battery before purchasing.

The BL-S3 410mAh 3.8V battery has a typical capacity of 410mAh (1.6Wh) and a rated voltage of 3.8V. Charge limit voltage is 4.4V. It is a Li-Polymer battery built with Grade A cells and is CE, RoHS, and UN38.3 certified. The watch supports 5V/0.85A (4.25W) charging via the included charging cradle — according to the official LG user manual, the power adapter output is DC 5V, 0.85A. Charging the G Watch through a USB cable attached to a laptop computer takes the same time as with the original power adapter. With a cycle life of 300‑500 full charge cycles, the BL-S3 410mAh 3.8V battery is designed for long‑term durability. For best results, always use the original LG charger that came with your watch.

Professional installation is strongly recommended for LG G Watch R battery installation. The watch has a sealed design — according to user experiences, the G Watch's battery can't be removed without proper tools, and attempting to open the watch by non‑qualified individuals can cause damage to the device. The process to replace BL-S3 battery in LG G Watch Urbane requires a Torx T4 screwdriver to open the back case, careful prying to avoid damaging the display or internal components, and proper resealing after replacement. The watch has no official IP water resistance rating, so water seal maintenance is not a concern after replacement. If you choose DIY smartwatch battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), use plastic tools to avoid damaging internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15‑30 for labor.
