So the batteries in my UPS died, again, and prices for new SLA batteries was in the $70 range. A DIY project will probably cost me more, even with free 18650 cells on hand, but I don't like that the SLAs keep failing after four years despite only one cycle and a very resonable float voltage.
These boxes for DIYing a replacement battery does show up on image search, but does anyone here have any expereince with where to buy them and if it's worth the hassle?
