Replacement Battery for Nighthawk M1 (MR1100)
Where can a Nighthawk M1 (MR1100) be purchased? I believe the mobile hotspot device takes a W-10 battery? Thanks in advance Model: MR1100|Nighthawk LTE Mobile Hotspot Router
Ahhh,
I just remembered, some on this board have reported that the MR1100 is very conservative when it comes to device and battery temperatures. That is to say it will not attempt to charge the Li-ion battery if the temp is too high. Where high was a fairly low temp (~35-40C) as electronic devices go.
Device and battery temps are reported on the Admin page. Some are even running the device in fixed installations with battery and battery cover removed, elevated, with fans and heatsinks to keep it cool.
If you have multiple devices which do not seem to be properly charging the battery it is most likely 1) the charger, 2) charger cable, 3) temperature.

According to the User's Manual, the cutoff point for high temperature during charging of the battery is 113F or 45F. On my MR1100, with an infrared thermometer on the Battery when at 94% charged, it shows 109.0°F (42.8°C) while charging. The FLIR Camera I have shows 109.2°F (42.9°C) on the warmest part of the battery and over the connector with the Anker USB3.0/USB-C cable from the Charging Port of the Anker Quick Charge 3.0 60W 6-Port USB Wall Charger and from the QC3 port there is a temperature of 130.7°F (54.8°C) on the connector, not the battery. In the Home page of settings under the Diagnostics tab, the Device temp shows 47°C and the Battery at 43°C. The In-Line USB meter I have shows 4,197mv and 0.730A and that the battery is on Quick Charge. It never went higher than 95% while charging, and now is showing 92% and a Battery Temp with the Flir of 87.0°F (30.6°C).

Device and Battery temps are reported on the Diagnostic Tab of the Settings Tab on the NetGear/AT&T Windows App in Chrome. When I ran the MR1100 overnight without the Battery and the case sitting on the Window Ledge, this morning the device was off-line.

The Charger is an Anker 6-Port with one QC3.0 and 5 QC2.0 ports and the Cable is also an Anker, USB3.0-USB-C. The MR1100 is the only device plugged in so far and it is sitting on the Window Ledge of a window that is cool to the touch. It was 30°F overnight, just outside the window. It is only 66°F outside now, and the window glass is at 64°F. The window is in shade all day, under 3-60 feet Blue Spruce Trees.
