🔋 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.

Compatibility Note: Fits Realme GT Neo 5SE (RMX3700) only. This battery uses a dual-cell design (7.82V) — please confirm your original battery voltage before ordering.

Frequently Asked Questions

The BLP991 battery is compatible with Realme GT Neo 5SE (model RMX3700). The GT Neo 5SE was released in 2023 featuring a 6.74-inch 144Hz AMOLED display and supports 100W SUPERVOOC fast charging. If your GT Neo 5SE battery drains quickly or won't hold a charge, this is the correct replacement. For reference, European retailers sell this battery for €25.99 ($28), and US retailers for $28.99. Please verify your device model in Settings > About Phone before purchasing.

The BLP991 battery has a total capacity of 5500mAh (typical) / 5360mAh (rated) and a rated voltage of 7.82V. This is because Realme GT Neo 5SE uses a dual-cell series design (2S) — two 2750mAh cells connected in series inside a single battery pack, producing 7.82V total. Full charge voltage is 8.9V (4.45V per cell). The battery supports the original 100W SUPERVOOC fast charging capability of the GT Neo 5SE. Some retailers list the single-cell capacity as 2680mAh, while the typical total capacity is 5500mAh.

Professional installation is strongly recommended. The Realme GT Neo 5SE has a sealed design with strong adhesive. Replacing the battery requires heating to soften adhesive and careful prying to avoid damaging the AMOLED display. If you choose to DIY, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor. Realme official service charges 100-130 RMB ($14-18) for battery replacement.
