Input: I purchased this battery b/c it was a great price. But once installed in my Arris TM822g the battery light indicated that the battery was defective. I thought maybe it needed charging but after 24 hours the battery light on my modern still &#34;flashed&#34; indicating that the battery was defective or failed. So I am retiring it for a refund.<br /><br />The battery looked as though it may have been used and it did not come in its &#34;original&#34; packaging. This may also be why it was less expensive than most other batteries sold by other sellers.

When installed... battery was shown to be defective
