AT&T nighthawk battery not charging

[in2ndo]

Hi all.
So.. as a mobile hotspot .. I have this set up in my truck. The battery has stoped charging on a consistent basis.: I plug it in.. starts charging.. 2 minutes later.. it just stops. Only way to get it going again. Take the battery out.. put it back in and it starts charging again. So annoying. 200 hundred bucks of I need to deal with it.
I am somewhat tech savvy.. so I think I’ve done all that I could default to.. like take the battery out.. let it rest.. try a different chateger.. wire, etc etc etc..
the hotspot is used to provide WiFi in my truck.. that means.. it could sit parked for a few hours on 100 degree weather.:. If you can even call it that weather..
But I figured.. the company selling it.. knows this is a possibility... so it should work.
Any ideas ? And Thanks in advance .

And This stupid website is no help trying to post something.
