🔋 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 4G LTE portable router running longer with this B9010 2100mAh replacement battery. The TIANJIE MF901, D921, 9300, MTC 8723FT, and D-Link DWR-932 are popular portable WiFi hotspots that provide internet connectivity through SIM cards — essential for travel, remote work, and areas without fixed broadband. These devices rely on a rechargeable battery to maintain connectivity, and after years of use, the original battery capacity naturally degrades. This Li-ion Polymer battery restores the full 2100mAh capacity, bringing back the extended runtime these portable routers were designed for. 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 Travel and Portable Connectivity: 4G LTE portable routers are essential for staying connected on the go — whether you’re traveling internationally, working remotely, or need a backup internet source. The 2100mAh battery originally provided approximately 6-8 hours of continuous use, depending on network conditions and connected devices. After years of charging cycles, battery capacity degrades significantly. Common symptoms include: the router requiring more frequent charging, shorter runtime than when new, the device shutting down unexpectedly with battery remaining, or visible battery swelling. This replacement restores the original runtime, allowing you to continue using your portable router without interruption. The B9010 battery is also compatible with the N710 and ES-M5 battery models used in many of these devices — always check your original battery model before ordering. Unlike many modern devices, these portable routers typically feature a removable battery cover, making replacement quick and simple without special tools.
Compatibility Note: Fits a wide range of 4G routers and hotspots using B9010, N710, or ES-M5 battery models. Popular compatible devices include TIANJIE MF901, D921, 9300; MTC 8723FT, MTS 8723 FT; Tenda B9010, Tenda SC801; D-Link DWR-932, DWR-932M; MTC 81220FT; Anydata R150; Tele2 MQ531; and Digma DMW1969. Please confirm your original battery model before purchasing — B9010, N710, or ES-M5 printed on your existing battery.

This B9010 3.8V 2100mAh Li-ion Polymer battery is built with grade A cells and is CE, RoHS, and UN38.3 certified. For TIANJIE MF901 battery life after replacement, expect approximately 6-8 hours of continuous use on a single charge, depending on network signal strength and the number of connected devices. The B9010 2100mAh battery performance provides reliable runtime for travel, remote work, and outdoor connectivity. Physical dimensions are approximately 63.1 × 50.1 × 5.3mm — please measure your device's battery compartment to ensure proper fit. Charging the B9010 battery takes approximately 2-3 hours with the original router charger. For best performance, allow 2-3 full charge cycles after installation to calibrate the battery meter.

Replacing the B9010 battery in most portable routers is straightforward because these devices typically feature a removable battery cover. For B9010 battery installation in TIANJIE MF901 and D-Link DWR-932: 1) Power off the router completely. 2) Remove the back cover — most portable routers have a simple sliding or snap-off cover. 3) Locate the B9010 battery. 4) Disconnect the battery's small 2-pin connector by pulling the plug (not the wires). 5) Remove the old battery — it lifts out easily. 6) Connect the new B9010 battery — the connector is keyed and only fits one way. 7) Place the new battery in the compartment and snap the cover back on. For B9010 battery replacement in MTC 8723FT and Tenda routers, the process is similar. No special tools or heat gun required. For portable router battery health maintenance: 1) Use only the original router charger for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the router 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 router until it powers off, then charge uninterrupted to 100%. For 4G router battery care tips, stop using immediately if the battery shows any swelling.
