I found they would do exactly as you experienced. They would seem fine for a couple of months and then suddenly loose capacity. I don't know who makes their packs but they are not top grade and almost seem like an after thought.
Mine was a Spektrum battery, my club members battery is a JR unit, mfg in Japan. For a multi-hundred dollar transmitter, you'd think they would put in quality battery packs.
To bad he lost a $1000 model airplane because of a $40 battery. On my recommendation, he found an Eneloop direct drop in battery from batteriesamerica.com (I think)
