🔋 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 20W Dash Charge (OnePlus 6T) and 20W 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.
Designed for Extended Battery Life: The OnePlus 6T and 7 were known for their “fast and smooth” experience, but after 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 factory-spec 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 low‑voltage, high‑current technology that keeps the phone cooler during charging compared to standard high‑voltage fast charging. Whether you are still daily‑driving your OnePlus 6T or keeping a OnePlus 7 as a backup device, this BLP685 replacement will give it a new lease on life.
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 7 Pro (uses a 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.
