No, I didn't mean to give that impression, sorry! I was just leaning towards the Ridgid batteries because the cost for retail batteries was good (~$40 for 5 A-Hr on sale, and ~$30 for 3rd party), 3 year warranty (I thought I read they used to be 'lifetime', but that may have been a...

If you paid by credit card, you can go to customer service at most stores and ask for a duplicate receipt and if it's less than a year or so, they have always been able to do it for me...walmart, target, lowes and maaaaybe home depot for me, personally, over the past 10 years....but only because...

With very little rationalization, that's just going to hurt the wallet...and now I'll end up with two tool/ battery platforms for sure!

darkzero Yeah, I hear you on that. They appear to be about $20, from what I can see, couple that with ~$70 for a 5 A-Hr M18 battery and that's a little more than a DeWalt 5 A-Hr at ~$80. Starting to appear as though maybe not worth it on this particular path. I did look for Ridgid battery...

I don't know quite enough to be sure if it's "safe" to charge one manufacturer's batteries in another's charger. Apparently, some put the battery discharge protection circuitry in the battery and some put it in the tool. Assuming I get a match with Ridgid and DeWalt, I hope that does not mean...

For anyone else looking, fourjeepin, I found your adapter build thread: https://www.garagejournal.com/forum/showthread.php?t=317260 I don't know if I'm too gun shy to do 3rd party ridgid compatibles at ~$60/2 ( https://www.amazon.com/dp/B0842R7N9R/?tag=atomicindus08-20 ), but building this...

...I don't know. It's a DC9320, this one: https://www.dewalt.com/products/accessories/batteries-and-chargers/chargers/72v18v-nicdnimhliion-1-hour-dual-port-charger/dc9320 "Discontinued"...so, old? But did DeWalt make multiple Li-ion charger versions for pod/ post style packs?

On my drill and impact driver, the extra length added by the DeWalt adapter, with the 4/5 amp-hr batteries make the balance feel off or higher torque (moment of inertia?). Plus, setting them down upright feels like a precision maneuver...they're a bit close to tipsy. I do like the Li-ion...

I have 5 or 6 18V Dewalt tools of the pod/ post style which are still in very good shape. After looking for battery pack rebuilds for my DC9096/ DC9098/ DC9099s over the past 2 years, I have pretty much given up on them. I have now turned to 3rd party manufacturers/ sellers, but am having...

Billed by the hour! :bounce:

Okay, I don't understand your point or comparison here. My original point was that a crack could be started in or adjacent to a strain hardened region due to the local changing materials properties. The ultimate yield strength may never have been reached, for any of several failure mechanisms...

Strain hardening occurs (in almost nearly all metals) before the ultimate strength is reached. After ultimate yield strength is reached necking occurs, which is self perpetuating. There is also a decent chance the source material had a defect. If there is any significant sort of defect then...

I certainly would not argue that I and others do not make mistakes. However, your original statement was an absolute and about understanding "what a defect does to a product"...you move the goal posts when you switch to "know" [exactly what will happen in the future when the product is put into...

_Most_ consumers....let's not completely write ourselves off, here! :-)

You've got the causal relationship reversed. Stress-strain diagrams show strain measured as a result of applied stress. Most are tension based, and compression-based curves will vary from tension, primarily at high stresses. One could argue stress applied could be estimated with some...
