That's right, they are. The JR charging plug has the negative connection on the tip and the positive connection on the side. >Any reason to expect that I've done any damage to the battery? Yes. If you've discharged any or all of the cells and then charged them in reverse, they're likely to be permanently damaged. If so, after a normal charge they could appear to be okay but will quickly go dead when used. >Anything I should be doing or checking? You need to cycle the pack with a smart charger, such as a Triton, and see how many MAH the pack can now store. If it's significantly less than the pack's rating, which I believe is 600 MAH, then you'll need to replace the pack. Alternately, you can just give the pack up for dead and replace it, just to be safe. There are differing opinions among the guys here concerning NiCd vs. NiMh cells, but my own recommendation is to buy two four-packs of Energizer 2300 or 2500 MAH cells from a local department store, cut the wire harness from your old NiCd pack before recycling it (cut only one wire at a time), and build a new pack. You can charge it with the same charger you've been using, but of course it'll take longer because of the increased capacity.
