sorry, Brian but I must disagree about it being time for a new tool when the battery fails. I've got 4 cordless Makitas that are all in perfect shape. I've had 2 batteries die over the past year and just replaced one. 2 tools share that same type battery-18v. The cost of those 4 tools would be well in excess of $600. I'll be buying batteries every now and then as they fail. Now if I had DeWalt cordless tools, I'd be itching to move up to something better. Been there, done that already.
