Just got a new B&D Dustbuster 9.6v (CHV0600). $26 at Kmart.

If I leave it on the charger-cradle, it'll waste current just
warming the niCad or somesuch? How much?

Could use some help with the arithmetic.

Power Unit:
Input 120v 60hz 4.5w
Output 15v 130mA

If I just left it in the cradle, what would power consumption
for a full year look like? Numbers above are sufficient?

It 'pears I'm paying about 8 cent a kilowatt-hour ...

TIA,
Puddin'

Leaving it in the charger may shorten the life of the battery. B&Dsays
it is OK, but others say overcharging is not good.
Cost of new battery overshadows cost of power.

I leave my Dustbuster on the charger all the time it's not in use;the first
set of NiCds lasted 10 years.
There are NiCd designed specifically for trickle charge 24/7/365;DigiKey
stocks them.

Letting the Dustbuster NiCds self-discharge will shorten their life far
more than being left on the charger.
