I ordered a backup battery for my arruis TG1682g for internet and phone. the battery does not seem to fit. It clicks in but the backing does not snap shut. I ordered with a xfinity rep online. The battery model is BPB0448. I called twice and was told it was the correct battery and it was fine if the backing did not stay on?! She did not understand a lot of what i was saying and had to check many times to answer my questions I'm wondering if the wrong battery was sent to me?
There are slots in the battery bay. The fins on the battery need to line up with the slots. If they don't line up, you won't be able to insert the battery all the way.
