A Ghost could draw energy from battery in order to manifest. Quite often those investigating a haunting would find that the batteries used in EMF meters, camcorders, voice recorders and cameras would be instantly drained or would malfunction due to fluctuations in energy levels. That said it take an awful lot of energy so a ghost is unlikely there tinks. Check to dates of the multi pack, even batteries have a sell by date and can discharge over time. But the most likely cause is furring on the contacts inside the clocks. Just get any implement with an abrasive tip and gently rub the contact points until you can see shiny metal again…..By the way, take your time and don't take to much of the contacts surface off
