🔋 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.

Bring your OnePlus 6T or OnePlus 7 back to life with this BLP685 3700mAh replacement battery. Both devices were iconic in OnePlus history — the 6T introduced the in-display fingerprint sensor and waterdrop notch, while the OnePlus 7 delivered flagship Snapdragon 855 performance at a mid-range price. This Li-ion Polymer battery restores the full 3700mAh capacity for all-day usage and supports the original 20W Dash Charge (OnePlus 6T) and Wrap Charge (OnePlus 7) fast charging protocols. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
What Makes OnePlus 6T and 7 Special – And Why Battery Replacement Matters: The OnePlus 6T and 7 were known for their “fast and smooth” experience, but after 5-6 years of use, the original BLP685 battery has likely degraded significantly. Users typically notice: battery draining faster than before, unexpected shutdowns at 15-30% charge, slower charging speeds, or the phone needing two charges per day. This replacement battery restores the original 3700mAh capacity, bringing back the reliable all-day battery life that made these phones great. The battery also preserves the 20W fast charging capability — OnePlus’s proprietary low-voltage, high-current technology that keeps the phone cooler during charging compared to standard high-voltage fast charging. Whether you’re still daily-driving your OnePlus 6T or keeping a OnePlus 7 as a backup device, this BLP685 replacement battery will give it a new lease on life. The OnePlus 7 also supports Warp Charge 30 (only on the 7 Pro variant; the standard OnePlus 7 uses 20W Wrap Charge, which is fully compatible with this battery).
Compatibility Note: Fits OnePlus 6T (A6013) and OnePlus 7 (GM1900, GM1901, GM1905) only. Please confirm your battery model before ordering — BLP685 is printed on your original battery. This battery is NOT compatible with OnePlus 6, OnePlus 6T McLaren Edition (uses same battery but verify first), OnePlus 7 Pro (uses different BLP687 battery), OnePlus 7T, or OnePlus 8 series. The OnePlus 6T and 7 share the same battery design, but the 7 Pro has a larger 4000mAh battery with different dimensions.

For OnePlus battery health maintenance: 1) Use only the original OnePlus Dash/Wrap charger and cable — other chargers may not support the proprietary fast charging protocol. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the phone to high temperatures (above 40°C / 104°F). 4) For long-term storage (over 2 months), keep the battery at approximately 60% charge. 5) Perform a full calibration cycle after installation: drain until auto-shutoff, then charge uninterrupted to 100% using the original charger.
