ok so today I was at my local goodwill dropping off somethings, usually, I will go inside to the back where they have the electronics and see if they have any hidden gems. While back there I came across 3 Belkin rev B At&t Uverse backup batteries upon inspection 2 had good batteries and ones battery was bad I talked them down to me purchasing all 3 for $20 a great hall in my opinion. When I got home and inspected each one of them the barrel connectors on them look the same as on the C-4 HE and I was wondering would it be possible to use them as a backup battery for the He the specs are as followed
