DEWALT DCS520B 60V MAX* Circular TrackSaw, 6-1/2in

A little backstory: I purchased PDCS520B to replace an earlier version of Dewalt's 28v cordless tracksaw. The Dewalt 28v version was discontinued, and the batteries are no longer available. There is/was, in my experience (and if you do an internet search you will find others had the same problem experience), a problem with the batteries losing their charge, and once the battery cells dropped below a certain voltage, they could no longer be charged AT ALL! The 28v came with 2 batteries, but reached a point of low voltage, to which they couldn't be charged any longer. So I purchased a 3rd 28v battery online, new in original packaging, at the major online auction site. Unfortunately, this battery too could not be charged. So another $100 down the drain. So, instead of purchasing additional batteries, in a futile attempt to save the 28v saw, I decided to purchase this 60v flex volt cordless tracksaw. The DCS520B functions perfectly, cuts smoothly without slowing down, ramps up to speed quickly, and blade brake stops the blade quickly. I am very satisfied with this version. I just hope there aren't any battery issues with the flex volt platform. If there are future problems, I just hope Dewalt will stand behind their product, instead of abandoning the flex volt platform, and leaving their customers in the lurch. How does the old age go? 'Fool me once, shame on you. Fool me twice, shame on me.' I will guarantee I will not purchase a 3rd Dewalt saw. FWIW, I had searched in hopes that Milwaukee offered a cordless tracksaw in their M18 platform, but unfortunately A Milwaukee only offers a cordless tracksaw for sale in Europe, but not the United States. Milwaukee has kept their M18v platform around for decades. They could have changed platforms, like Dewalt, and forced their customers to buy all new tools, but Milwaukee did not. Instead, Milwaukee developed new tools around the same M18v battery platform, AND milwaukee still supports their previous tools/platforms, and does not abandon their loyal customers. Milwaukee, PLEASE OFFER YOUR CORDLESS TRACKSAW TO YOUR U.S. customers. (caps for emphasis, not yelling :) ) I purchased the Dewalt DCS520B from Albany Tools here on Amazon. They were great, shipped quickly. Excellent packaging. And arrived on time. Thank you!
