![]() ![]() We can see a rated capacity of 24Wh, which isn’t very impressive. Right… it’s in my shop as a battery pack, it’s getting opened. The bottom contains the usual warnings I’m about to partially ignore. That’s a 16S NiCd voltage rating - for a 5S lithium battery, you might call it 18.5V (3.7V * 5), you might call it 21V (4.2V * 5), or… you might call it whatever you want, because marketing decides what to use, and battery powered tools are incredibly tolerant of a wide range of input voltages. ![]() ![]() In any case, we’ve got a “19.2V” battery. They used to have the perk of “If you break a simple tool or socket, take it to Sears and they’ll replace it,” but where’s your closest Sears? Can you answer that without pulling up a map application and checking? I didn’t think so. I can’t say I’m a huge fan of Craftsman anymore. The “stalk” style connection and the larger base are common with the NiCd packs. This battery looks to me like a lithium replacement for the old NiCd batteries common in the early battery powered tools. You can find the OEM packs for about $40 on eBay, with various aftermarket clones for a bit less (including some with a nice capacity bump - buy the 4.0Ah packs if you need one of these and don’t mind some extra weight). Craftsman 19.2V DieHard 315.PP2011 Lithium-Ion Battery It’s always interesting to see how different companies approach much the same problem. If you’re bored of tool battery teardowns, you could always send me more interesting things to mess with! I enjoy poking around tool batteries, and a lot of the ones I pull apart are “new to the internet” in that they haven’t had a detailed teardown before. They’re both lithium, and I’m going to dig into both of them, because that’s what I do with old batteries I pick up out of junk bins. It’s time for more tool battery teardowns! This week, I’ve got a Craftsman 19.2V DieHard battery, and a cute little Ridgid 12V battery. ![]()
