Because drills draw a higher current,and need a better connection between
cells,thus the welded straps.
For people who only use their cordless drill every couple of months,get a
Li-ion system;they retain a useful charge for about 6 months.
they COST,though.
With NiCds,it's basically "use it or lose it".
