✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

Keep your Samsung Galaxy M11 powered throughout the day with this HQ-S71 5000mAh replacement battery. Compatible with Galaxy M11 models SM-M115F, SM-M115F/DS, SM-M115M, and SM-M115M/DS, this Li-ion battery delivers the factory-rated 5000mAh capacity — providing extended power for calls, messaging, social media, and multimedia. The Galaxy M11 was released in May 2020 featuring a 6.4-inch PLS display, Qualcomm Snapdragon 450 processor, 3GB RAM, 32GB storage, and supports 15W fast charging via USB Type-C. For reference, third‑party retailers sell this battery for approximately $17 to $25.
Built with Grade A Li-ion cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. The phone supports 15W fast charging via USB-C — a full charge takes approximately 2-3 hours. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term durability. The battery is not user‑replaceable — professional installation is strongly recommended as the phone has a sealed back cover with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with Samsung Galaxy M11 (SM-M115F, SM-M115M) series only. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best 15W charging performance, use the original Samsung 15W fast charger (9V/1.67A) that came with your phone. If you don’t use the device for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.
