AirCard 770s no battery error

I received a Re-Furbished AC771S (Netgear Zing) from FreedomPop.
It came with a W-8 Battery.
When powered-up, It displays "NO BATTERY" status on top line & "Battery Level Critical" message, then powered down shortly.
It was Charged overnight, Same symptoms.
FreedomPop sent me a W-5 replacement battery.
The Hotspot seemed to powers-up correctly & shows % Battery Charge & Senses that a Charger is attached.
But, after ~15Min, it reverts back to the "NO-BATTERY" display & "Battery Level Critical" message.
Removing the battery Cover has no effect.

Do I have a Defective HotSpot or just a Bad Firmware version ?
This seems to be a fairly common problem with this model of wifi router. I own two of them and the same problem has occurred with both of them shortly after one year of use.
Netgear does not seem to have a solution as near as I can tell. It tends to occur after the year warranty expires so they don't seem to care that they have a s___ty problem. I, and others, have mused that it might be intentional.My solution is to run mine on a USB power supply cord. However, It is not a stable solution as the modem shuts or restarts at seemingly random intervals at least once per day and often multiple times. When it shuts down, I have to unplug the power cord and reinsert to restart the modem.It does seem to be more stable than the "no battery" error which seems to occur when the battery level reaches minimum unplugged or maximum while plugged.I'm on Sprint with mine and they say a Pocket Wifi unit would also deal with my data plan. I'm currently researching that option.Sorry for your trouble. You might demand a refund for a faulty product.I have a 771S on Sprint and it worked great for 2 yrs. but started with the no battery issue last week. So I ordered a new battery thinking that was the problem. While I was waiting for the new battery I read a post where someone said it was a software change and it would work if you lay it on a blue ice pack. I tried it and it worked on the old battery fine and I'm still using it on the new battery as it didn't help the issue. As long as it is cold it works but if it gets back to room temperature it says no battery and locks up. Sprint support refers me to Netgear and Netgear refers me to Sprint.
