✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

Restore the battery life of your Amazfit Bip smartwatch with this PL402120V 200mAh replacement battery. The Amazfit Bip (model A1608) was released in May 2018, featuring a 1.28-inch always-on transflective color display, built‑in GPS and GLONASS, PPG optical heart rate sensor, barometer, and IP68 water resistance. The watch weighs only 31 grams and delivers up to 30‑45 days of battery life on a full charge under normal usage. This Li-Polymer battery delivers the factory-rated 200mAh capacity, restoring your watch to its original performance.
Built with high-quality Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, and short circuit. CE and RoHS certified for safe transport and use. With a cycle life of over 500 cycles maintaining 80% capacity, this replacement battery is designed for long-term reliability. For reference, third-party retailers sell this battery for approximately $15 to $35.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches PL402120V. This battery is compatible with Amazfit Bip A1608, Amazfit Bip S, and Amazfit Bip Lite. The watch has an IP68 water resistance rating — professional installation is strongly recommended to maintain water resistance after replacement.
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. If you don’t use the battery 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 PL402120V battery for Amazfit Bip A1608 is compatible with Amazfit Bip (model A1608), Amazfit Bip S, and Amazfit Bip Lite. The Amazfit Bip was released in May 2018 featuring a 1.28-inch always-on transflective color display, built‑in GPS and GLONASS, PPG optical heart rate sensor, barometer, and IP68 water resistance. If your Amazfit Bip battery replacement is needed because the watch drains quickly or won't hold a charge, this is the correct PL402120V battery. Please verify your watch model on the back case and check the battery model PL402120V printed on your existing battery before purchasing.

The PL402120V 200mAh 3.8V battery has a typical capacity of 200mAh (0.76Wh) and a rated voltage of 3.8V. Charge limit voltage is 4.2V. It is a Li-Polymer battery built with Grade A cells and is CE and RoHS certified. The Amazfit Bip supports magnetic charging via 2Pin Pogo Pin — a full charge takes approximately 2.5 hours. The original 200mAh battery delivers up to 30‑45 days of battery life on a single charge under normal usage, or up to 22 hours of continuous GPS tracking. For best results, always use the original magnetic charging dock that came with your watch.

Professional installation is strongly recommended for Amazfit Bip battery replacement. The Bip has a sealed design with IP68 water resistance rating — it is dust‑tight and can be submerged in water up to 1.5 meters for 30 minutes. The process to replace PL402120V battery in Amazfit Bip A1608 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 $15‑30 for labor, and IP68 water resistance may not be fully guaranteed after non-professional repair.
