🔋 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.

Compatible with: Samsung Galaxy Watch 5 40mm (SM-R900, SM-R900F, SM-R900N, SM-R905, SM-R905F, SM-R905U), Galaxy Watch 5 40mm all carrier variants

Restore the full performance of your Samsung Galaxy Watch 5 40mm with this EB-BR900ABY 284mAh replacement battery. The Galaxy Watch 5 40mm was released in August 2022, featuring a 1.2-inch Super AMOLED display, sapphire crystal glass, and IP68 dust/water resistance — rated for submersion up to 1.5 meters for 30 minutes. This Li-ion battery delivers the factory-rated capacity, supporting continuous health tracking, sleep monitoring, notifications, and workouts without daily recharging. The watch supports WPC-based wireless charging — when charged for 30 minutes with the included 5V/2A charger, the battery reaches approximately 45% capacity.
Built with high-quality Grade A Li-ion 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. For reference, third-party retailers sell this battery for approximately $12 to $36. Professional installation is strongly recommended as the watch has a sealed design with IP68 water resistance — proper resealing with fresh adhesive is required to maintain water resistance after replacement.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches EB-BR900ABY. This battery is compatible with Samsung Galaxy Watch 5 40mm SM-R900, SM-R900F, SM-R900N, SM-R905, SM-R905F, SM-R905U, and all carrier variants of the 40mm model. NOT compatible with Galaxy Watch 5 Pro (44mm) or the larger 44mm version — those use EB-BR910ABY with 397mAh capacity. Professional installation is strongly recommended — the watch has a sealed design requiring careful opening and proper resealing to maintain IP68 water resistance.
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 Samsung wireless charger that came with your watch. 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.

Professional installation is strongly recommended for Samsung Galaxy Watch 5 battery replacement. The Galaxy Watch 5 has a sealed design with IP68 dust/water resistance — it can be submerged in up to 1.5 meters of water for 30 minutes. The process to replace EB-BR900ABY battery in Galaxy Watch 5 40mm requires heating to soften adhesive, careful opening of the sealed case using plastic tools, and proper resealing with fresh adhesive to maintain IP68 water resistance after replacement. Water resistance may be compromised if the watch is not properly resealed. 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 the display or internal components, and never reuse a battery after removal. Third-party repair shops typically charge $20-40 for labor, and IP68 water resistance may not be fully guaranteed after non-professional repair.
