Maybe I am completely wrong but this behaviour rhymes quite well with a faulty (old) battery which reports being charged but actually cannot really hold the charge. I suggest taking it off and verifying it with a voltmeter , preferably while having a consumer connected as well ( like a good old 12V incandescent light bulb, as those used for cars i.e. 25-45W or so )
