When powering up my 4-year-old Toshiba  today, the warning "RTC battery
is low..." came up; first time it has ever done that.

According to the handbook, the Real Time Clock battery does recharge
when the power is 'on'; charge time 8 hours.

Although the laptop has not been used for 2 weeks, in the period up to
then it was powered up (wih mains connection) for at least 8 hours
each day for 3 days.

Presumably this indicates the Ni-MH RTC battery is failing.
Is this typical after 4 years?
   (Seems to be for Li-Ion batteries...)
