It's been my experience with rechargeable batteries that as they reach their cycle limits, their ability to take a charge declines, thus the charging circuit tries to "push charge" ... and the battery fails to hold it, so the conflict between the dying battery and the over worked charger presents a "no win" for either one.
I would suggest a new battery is an easy fix, before it also "cooks the charge circuit".
