Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches Li3930T44P4h794659. This battery is compatible with ZTE MF985 (AT&T Velocity 2), ZTE MF288 Smart Hub, and AT&T Velocity 2 4G LTE Mobile Hotspot. The battery is user-replaceable — most of these devices have a removable back cover for easy battery access. No professional tools required for installation.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best charging performance, use the original USB Type-C charger that came with your hotspot. If you don’t use the battery 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.
