I suspect this has been well covered before but...

I have a cheap Direct Power (Screwfix supplied) drill. Unsurprisingly
the Ni-cads are failing after 12 months or so use.

I looked at various battery supply sites and failed to find a match.

A complete new drill plus 2 batteries from Screwfix is around 35ukp
which is roughly the cost of a single *quality* battery elsewhere.

With global warming etc. in mind, I am reluctant to throw away a working
tool!

The Direct Power batteries are easily disassembled so re-celling is an
option. So.... assuming I have the cheapest possible cells... what are
my options?

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?
