Nighthawk M1 Battery charging

[CTWanderer]

I have a brand new Nighthawk M1 that I'm charging the battery before I get a SIM card and set up service. I've had the charger plugged in for over 24 hours and the battery is only showing about a 3/4 charge. How long does it trake to charge a battery in this unit? Over a day seems to long. Is not having a SIM card installed causing it to take longer?

Netgear has set up a community forum specifically for the Mobile Router products. Most of the people who watch that forum are more likely to have experience with mobile routers and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Please advise your device SKU name and FW version on the device. It is better to make sure your device is upgraded to the latest release first before checking the battery chaging again.
