Many of you need to crawl out of the cave.
The cordless tools you bought/used in the 1990's and early 2000's are a distant memory of poor performance, poor quality, poor durability and horribly financed design and production.
The new stuff, even from Ryobi, is great. The scale is still there - Ryobi is servicable for a long period to the homeowner and a short period to the construction worker who can't not buy that 18 pack on a daily basis leaving him with no money for good tools.
I bought a 4-piece Ridgid Brushless 18V kit with 4.0a/hr batteries last year. Hammer drill, impact driver, 7-1/4" blade right circ saw and grinder.
I've used every single tool under stress and I'm happy with the performance and battery life. Not only battery life but time it takes to fully recharge.
It takes about 35-40 minutes to go from very low to fully charged....and that will last long enough for you to take a break, lunch, whatever. If you're using these new Li-On 4+ a/hr battery-powered tools to make a living, you need to buy a couple spares of batteries anyway.
I don't have one nor have I used a sliding compound miter saw from Makita or others or any other 18-36v tools from Milwaukee, Dewalt or Makita, but I have seen them in action by folks I trust and they are sharp. Nobody complains about battery life, nobody complains about performance, etc.
It is clear many of you don't venture too far past a receptacle to plug your 15' extension cord into, so you don't understand the beauty of the modern cordless tools. These new tools are better, faster, more powerful and do a much better job of the old versions. They are, in many cases, just as good or better than the corded models.
There's nothing weird about my Ridgid Cordless Circ saw. It looks like a corded saw, but there's no cord. It works just like one, too. But I can carry it around a site/building/400' away from where I was at 3 minutes ago and it will cut. Same with the hammer drill.
I've used the 4-1/2" angle grinder for 2+ hours on a single battery charge.
Are you telling me that you can't bother with another battery charging during those two hours to keep a cord away from your work?
You can have a single Honda EU2000i generator going, charging 10+ batteries at one time, with 6 skilled craftsmen using battery-powered tools, no cords, etc. It's also clear that many of you don't work in heavy industrial/commercial job sites where there are pretty strict requirements for extension cord usage.
