1. Don't leave it plugged into the charger all the time.
and, more importantly,
2. Simply use the device more often to drain it down, and cycle it.

I'm envisioning a 41C/71B programmed to wake up periodically to exercise the drive but now the problem extends to the NiCd battery in the 41Cs case .

But in all fairness, even LiON batteries like to be regularly used....otherwise capacity quickly goes down.
Good luck,

Two LiFePo4 cells would work........
