Hi,
I am meant to be revising so have decided to repair a dustbuster
instead.
It is a 7.2v model and the transformer to charge it is knacked. Thus, I
was thinking of running it of a 9.6v AA nicad pack for which I have a
charger with a nice plug that would make life easy.
I have fitted the pack and the suction is great, motor doesnt seem to
get too hot and all would be well... but the batteries get absolutely
scortching!
How can I stop this happening? Do I need to put a resistor in to limit
current flow (but that would reduce suction I assume?) or can I run two
packs in parellel (current drawn will be the same - get 2x battery
life and the heat divided between the two packs).
Other option would be to use another battery type - an ideas? NiMH?
Lead-acid?
I know buying another one would be easier, but I'd rather experiment
Cheers
