I’m not sure if the battery packs for a couple of cordless tools are near dead or not. Anyone know of a way to test them to make sure?

Duh - put them in the drill and try to drill something difficlult???
Or - charge them, measure the voltage, put a 1 C resistor across them (1C for a 18 V 1.7 A-hr NiCd = 10.6 ohms, and measure the voltage on a strip chart or take a reading every 2 minutes for a half hour and compare to the normal discharge curve (published by batt mfg)
My local Quikset store has a gala every now and then where vendors display stuff. Last summer I was there when I trashed a DW circsaw, I wandered around and DW had a tester set up..bring your batts and if shot, get 20$ off a new one, OR if still under 2yrs IIRC, a free batt.
They tested 5 or 6 of mine, and one was iffy..they gave me new one on the spot, and it was out past the warranty period.
So, with that said, frequent your local monger and find out when the next "Gala" is..
BTW, I did not see any other maker doing the same..
YMMV
