Will better replacement cells work OK with the supplied charger? Can I
change to Ni-mh or whatever? Who does one go to for advice and supplies?

I had the same dilemma with my B&Q 18 volt cheapie. New decent cells
(Sanyo) made the actual drill perform *far* better - the lower internal
impedance gave better low speed control and torque. I also modified the
charger to a 1/10th constant current type - and use a timer to prevent
overcharging. The charger on mine consisted of a simple DC power supply
with a series resistor - ie no electronic control. A look inside the base
should show if yours is this poor.

It seems to have knobs and bells beyond my ken:-)

I have an idea the charge current is connected by an encapsulated relay
as there is an audible click as the LEDs change over. Unfortunately the
legend on the i/c was hard to read without a lens but I can look more
carefully if it helps.

You might look for special offers of a decent brand same voltage battery
on Ebay etc - and rob that of its cells. They are usually the same size.
I paid near the same price (trade) for the Sanyo cells as the drill cost
new. But they're still fine some 4 years later.

Not that many 24V batteries about...
