The worst part about the ones with welded on tabs is the price, outfuckinrageous. Some years ago at work, I found that all the laptops we had were draining the CMOS battery once the main battery died while they were in suspend-to-ram. The cost of replacing hundreds of em would have been ridiculous so we bought em in cheap packs of two. As you can see from the pictures, I fashioned me a make-shift spot welder from a large 12V battery and 15P power cord, tore all the tabs off the old ones, put some heatshrink on the new batteries and had myself a sufficiently fun day. Sharpening the prongs and bending em close together is all it took to get perfect welds nearly every time. Just a quick rocking of the plug from one side to the other, super easy.
