The charger for my McCulloch 18V drill (Model 7488) has these specs: 18V Adaptor
Input: 120VAC, 60 Hz
Output: 18VDC, 400 mA
Model: TEAD-48-180400U

I hope this info helps you source a charger from other outlets.

Yes you can. On tools, 18 volts is 18 volts. Tools don't 'know' how the power is being created, either by Ni-Cad or Li-Ion means. Chargers are totally different. Most Li-Ion chargers can charge older Ni-Cad and some Ni-MH batteries but older Ni-Cad chargers will charge Li-Ion battery untill they overheat and sometimes start on fire because older chargers can't detect when the Li-Ion batteries are full.

Your battery is shot. $75 - $100 for a new one.

does not appear to be a UK model.

it takes a 24V DC 200mA  The one I have is a Ktec Model KA12D240020034U

You will need he correct charger, the 24V will destry a very expensive battery.

is this a north american model.all i can find is model DC727 & DC728 model. charger model 9116 & battery is DC9096 may work.charger volts 110v ac. if your buying the individual part like batt & chgr its more expensive than buying the whole kit is cheaper. hope i answer your question
