🔋 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 flagship charging performance of your Realme GT5 with this BLPA23 2620mAh replacement battery. Released in August 2023, the Realme GT5 150W features a 6.74-inch 144Hz display, Snapdragon 8 Gen 2 processor, and industry-leading 150W fast charging technology. The device uses a dual-cell battery architecture where two 2620mAh cells work together to deliver a total of 5240mAh equivalent capacity, enabling the phone to fully charge in approximately 18 minutes. After years of daily charging cycles, the original battery capacity naturally degrades. This Li-ion Polymer battery restores the full 2620mAh per cell capacity, bringing back the blazing-fast 18-minute full charge and all-day endurance that made the GT5 150W a standout device. 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 Ultra-Fast Charging and Longevity: The Realme GT5 150W was designed for users who demand the fastest charging speeds available. The dual-cell 5240mAh total capacity battery originally delivered 18 minutes from 0% to 100% — one of the fastest charging times ever achieved in a smartphone. However, after years of daily use, the original battery’s capacity degrades. Common symptoms include: the device taking longer to charge than when new, reduced battery life between charges, unexpected shutdowns at 15-25% battery remaining, or visible battery swelling. This replacement restores the original 18-minute full charge speed and all-day endurance, extending the useful life of the device without the cost of a new phone. The BLPA23 battery is fully compatible with the phone’s proprietary fast charging technology, ensuring efficient and safe power delivery.
Compatibility Note: Fits Realme GT5 150W (RMX3820) only. Please confirm your battery model before ordering — BLPA23 is printed on your original battery. This battery is NOT compatible with the Realme GT5 240W version, Realme GT Neo series, or other Realme models. The 150W and 240W versions use different battery configurations; using the wrong battery may cause charging issues or incorrect battery reporting.
