🔋 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.

The OLAX MT10, OLAX MF982, and XINYI D623 are compact 4G LTE pocket WiFi devices designed for on-the-go connectivity.

Designed for Reliable Portable Use: The 3000mAh battery in these 4G pocket WiFi routers originally provided dependable power for travel, outdoor use, and daily mobile connectivity. After years of charging cycles, battery capacity degrades significantly. Common symptoms include: the device requiring more frequent charging than when new, shorter runtime, slower charging than when new, or visible battery swelling. This replacement restores the original runtime, allowing you to continue using your portable WiFi router without interruption. This battery uses advanced high-density cell technology with multi-layer safety protection, ensuring reliable performance for years to come.
Compatibility Note: Fits OLAX MT10, OLAX MF982, and XINYI D623 4G pocket WiFi routers.

If you need a 4G pocket WiFi battery replacement for your OLAX MT10 or MF982, this 3000mAh battery is the exact match. For OLAX MF982 battery compatibility, please verify your original battery capacity — this is a 3000mAh version which is thicker than 2100mAh alternatives. This battery is NOT compatible with XINYI D623 units designed for 2100mAh batteries (model B9010). If your portable WiFi router battery no longer holds charge as it did when new or runs out quickly, this 3000mAh replacement battery will restore the full performance.

This 3000mAh battery for OLAX MT10 has a typical capacity of 3000mAh (11.10Wh) and a rated voltage of 3.7V, with a charge limit of 4.2V. This 3.7V 3000mAh Li-ion Polymer battery is built with Grade A cells and is CE, RoHS, and UN38.3 certified. For best performance, allow 2-3 full charge cycles after installation to calibrate the battery meter. If your 4G WiFi router battery now requires more frequent charging than when new, this replacement will restore the original runtime.

Replacing the battery in your 4G portable WiFi router is straightforward. Most pocket WiFi routers like the OLAX MT10 and MF982 have a removable back cover. To replace the 4G WiFi router battery, power off the device, remove the back cover, disconnect the battery's small 2-pin connector, remove the old battery, and install the new 3000mAh battery before reassembling. For battery health maintenance: 1) Use the original USB-C charger and cable for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize the lifespan of the 3000mAh cell. 3) Avoid exposing the device to high temperatures (above 40°C / 104°F), especially while charging. 4) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 5) Perform a full calibration cycle after installation: drain the device until it auto-shuts off, then charge uninterrupted to 100%. For pocket WiFi battery care tips, stop using immediately if the battery shows any swelling.
