Ryobi One+ Lithium & NiCd Tool Battery Teardown

It's still May, and I'm still doing tool pack teardowns to get through the seemingly endless boxes of tool batteries in my office.  I'm a bit fuzzy on where they all came from, though I do faintly recall picking up a box of dead ones at some point in the past.

This week, I have a pair of Ryobi One+ batteries - one lithium, one NiCd.  This represents the "old generation" and "new generation" of a generation of batteries - they both run in the 18V tools, but one is the old style NiCd, and one is a new style lithium (though, as you'll see, early lithium).


Join me as I rip into another two packs!

DeWalt 20V Max 1.3Ah and 18V Nano Phosphate Teardown

Another week in May, another pair of tool packs in my series of tool pack teardowns!

This week, I'm back to DeWalt with a 20V Max 1.3Ah, and an older 18V "Nano Phosphate" pack - which has the weirdest cell layout I've ever seen.  The date code says 2007 - so this is another example of an early tool pack in the "Working out the details" phase of lithium tool packs.

Rigid 18V Lithium Ion Tool Battery Teardowns

This week, I'm continuing my tool pack teardowns with a pair of Rigid 18V Lithium Ion packs out of Canada - and, in one of them, 18650s produced in Canada!


These are older lithium packs (one is very definitely the oldest I've seen), the capacity numbers aren't that great, but they're interesting samples, good fun to pull apart, and have some surprises inside!

Read on to see what I've found!
