![]() The pack is spot welded together, as is normal, and the strips don’t bother going to the center of the cells. The underside shows the layout - nothing terribly exciting, but this might be a useful reference if you intend to build one. The hole in the pack is for the post in the base - this is just another screw in the top. This cardboard has a weak adhesive on it, but mostly comes off in one piece. The core of the pack is shrink wrapped with a cardboard layer on the top and bottom. ![]() No extra screws or anything - just a friction fit. With a bit of gentle persuasion, the battery pack slides out of the case bottom. The top comes off to reveal the normal 18V arrangement, with one cell shoved up the stem, and a pair of contacts. No security screws on this pack! Just normal Torx T10s. Otherwise, there’s not much beyond the normal NiCd warnings. I assume because then people might realize that the XR/XR2/XR+/XP7/whatever packs aren’t as different as might be hoped. I don’t entirely understand why the old NiCd packs include nothing about capacity ratings - it doesn’t seem like it would be hard. No thermal management, no balancing connectors, nothing extra. Unlike the newer lithium packs and their many-pronged interfaces, this pack has two pins. Nickel cadmium (NiCd) cells have a high self discharge rate - so sitting for a year or two makes them totally dead. It’s a 774g (1lb, 11.3oz) battery pack that’s almost entirely dead - as are all the ones I have here. This is a somewhat smaller battery, as might be expected for a lower voltage system. They look pretty similar on the outside, but the similar form factors conceal some (very) minor interior differences!Īre you interested? Well, if you’ve seen one NiCd pack, you’ve seen most of them - this is not one of my more exciting posts. I’ve got a 14.4V XR pack, a stock 18V pack, an 18V XR pack, an 18V XR2 pack, and an 18V XR+ NiCd pack. This week, I’ve got a huge pile of older DeWalt 18V NiCd batteries (and a lone 14.4V battery) that need to come apart so I can remove them from my office and get some space back. It’s the last week in May - so the last week of tool pack teardowns for a while.
