🔋 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.

Power up your Fossil Gen 5 smartwatch with this APP00296 310mAh replacement battery. Compatible with Fossil Gen 5 Carlyle HR, Julianna HR (FTW6035), Garrett HR, and Fossil Sport models, this Li-ion battery restores the original 310mAh capacity — providing all-day power for fitness tracking, notifications, GPS, heart rate monitoring, and Wear OS performance. The Gen 5 series features 1GB RAM, 8GB storage, speaker functionality, and supports magnetic rapid charging (up to 80% in under one hour). For reference, third-party retailers sell this battery for approximately $12 to $25.
Built with 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. With a cycle life of 600+ full charge cycles, this replacement battery is designed for long-term reliability. Professional installation is strongly recommended as the watch has a sealed design — the battery is not user‑replaceable without specialized tools. The watch has a 3ATM or 5ATM water resistance rating — proper resealing with fresh adhesive is required to maintain water resistance after replacement.
Compatibility Note: Please power down your watch and check your original battery label before ordering. This battery is compatible with the above-listed Fossil, Emporio Armani, and Michael Kors models. The watch uses a magnetic rapid charging cable — the original charger outputs 5V/0.5A (2.5W) via USB-A. Professional installation is strongly recommended — opening the watch case requires heating, careful prying, and proper resealing to maintain 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 magnetic rapid charging cable. 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.

The APP00296 310mAh Li-ion battery is built with Grade A cells and is CE, RoHS, and UN38.3 certified.

Professional installation is strongly recommended for Fossil Gen 5 battery replacement. The Fossil Gen 5 smartwatch has a sealed design with strong adhesive and is rated 3ATM or 5ATM water resistant — it can withstand splashes, rain, and submersion up to 50 meters but is not designed for diving. The process to replace APP00296 battery in Fossil Gen 5 requires heating to soften adhesive, careful opening of the caseback using plastic tools, and proper resealing with fresh adhesive to maintain 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 AMOLED display or internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor, and water resistance may not be fully guaranteed after non‑professional repair.
