Magsafe Battery Pack not holding charge
My Magsafe battery pack is not holding charge itself. It charges my phone when the battery pack is connected to a power source and my phone is then connected to the battery pack, but it doesn't work when disconnected. I've given it plenty of time to charge on its own using a known working cord and brick and it will still have no charge even after days. It's stopped working only a week or so after I bought it.
