Sound cuts out until I give it a nudge or smack.

After prolonged use, my mini soundlink will suddenly just go silent. It is always hooked up to its AC adaptor and at full charge. If I smack it, the sound instantly returns. I believe it to be a bad connection with the battery. If I pull the battery out and replace it, the sound won't cut out for a while longer. I don't want to drop the cash on a new battery if it's the connection between the speaker and the battery that is faulty.
