Keep your ZTE Blade A36 or A56 running throughout the day with this E6739-N 5000mAh replacement battery. The ZTE Blade A36 features a 6.75-inch 90Hz display, Unisoc T7200 octa-core processor, and runs Android 15 with Google services — all powered by a long‑lasting 5000mAh battery. This Li-Polymer battery delivers the factory-rated 5000mAh capacity (19.25Wh) for all-day usage. The device supports 10W charging via USB Type-C — a full charge takes approximately 2.5-3 hours. For reference, third‑party retailers sell this battery for approximately $18 to $25.
Built with Grade A Li-Polymer 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. 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 ZTE Blade A36 and ZTE Blade A56 (including A56S variants). 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 10W charging performance, use the original USB Type‑C charger 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.

🔋 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.
