Revive your OPPO device with this BLP765 4025mAh replacement battery. Released in early 2020, the OPPO Reno 3, A91, Reno 3A, and F15 represented OPPO’s mid-range lineup featuring AMOLED displays, in-display fingerprint sensors, and the signature VOOC fast charging. Remarkably, all four models share the identical BLP765 battery — a rare cross-compatibility that makes this replacement battery useful for multiple devices. This Li-ion Polymer battery restores the full 4025mAh capacity for all-day usage and supports 30W VOOC fast charging. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Four Phones, One Battery — What Makes BLP765 Unique: The BLP765 battery is a rare example of a single battery model powering multiple distinct phone generations. The OPPO Reno 3 (CPH2043) was a slim 7.96mm device with a 6.4-inch AMOLED and MediaTek Helio P90. The OPPO A91 (CPH2021) offered a similar 6.4-inch AMOLED with 48MP quad cameras. The OPPO F15 targeted Indian and Southeast Asian markets with a lightweight 172g design. The Reno 3A was Japan-focused with IP68 water resistance. Despite their different market positioning and regional variants, all four share the BLP765 battery — making it easier for repair shops and users to stock a single replacement. If your phone now requires multiple daily charges, dies during use at 15-30% battery, or takes longer to charge fully, this BLP765 replacement battery will restore original performance. The 4025mAh capacity was competitive for 2020 and still provides a full day of moderate use in 2026, making battery replacement a cost-effective alternative to buying a new phone.
Compatibility Note: Fits OPPO Reno 3 (CPH2043), OPPO A91 (CPH2021), OPPO Reno 3A, and OPPO F15 (CPH2021). Please confirm your battery model before ordering — BLP765 is printed on your original battery. This battery is NOT compatible with OPPO Reno 3 Pro (which uses BLP755 battery), OPPO Reno 4 series, OPPO A92, or OPPO F17 series. The Reno 3 Pro has a different battery capacity (4025mAh but different model number and connector orientation). Always verify your battery matches BLP765 before purchasing.
