That may not be advisable, given the continuous constant-current trickle
charger in the CPU power supply. The Panasonic "Nickel Metal Hydride
Technical Handbook" recommends charging for no more than 10-20 hours,
"The overcharging of nickel-metal hydride batteries, even by trickle
charging, causes a deterioration in the characteristics of the
batteries. To prevent overcharging by trickle charging or any other
charging method, the provision of a timer to regulate the total
charging time is recommended."
Panasonic's "Nickel Cadmium Batteries Technical Handbook," on the other
hand, says explicitly that continuous trickle charging for Ni-Cds is a
recommended charging method.
