ST1 recoup 2 even when battery is at 100%

My two year old ST1 used to only display RECOUP 2 when breaking if the battery was under 70% full, which is the expected behaviour. Now i notice this happens even when the battery is at 100%, and I'm worried this is going to damage the battery by overcharging. Does anybody how this can happen? The front light was changed recently and I'm wondering if there is a connector or sensor that was damaged, or came loose. I'm not familiar with the circuitry.
