You can run all that off 3 chargers worth of batteries?! I guess you're not using all of them at once so can rotate.
I get the utility of battery stuff but if you're PAT testing 1 thing you might as well do 20. Then again we do in-house PAT testing so it's not big deal or cost to maintain the list and add new stuff. Plus the focus is on process rather than occupational safety so 'good working order' is specified on RAMS/etc rather than PAT testing, especially as it's no longer a a legal requirement.

Obviously some of those tools can't be run off a battery. Large breaker and large sds being the obvious ones you can get a battery operated compressor but the tank is tiny and much beyond 3/4 charge on the battery the compressor itself can't keep up with really heavy continuous use.
But yeah if you're talking some of the big modern batteries (DeWalt flexvolt is the only one I've had any personal experience with). You can - your battery outlay is huge.

Test 2 - 3 chargers Vs off the top of my head:
I could go on but that is what I will likely have starting on a large commercial site (not that I do that much these days) and ALL of the tools listed above would be kept current in terms of PAT testing. Plus you lose the headache of maintaining a register of those items (potentially duplicate as you could have 110v and 240v for all those tools). Also if the principle contractors health and safety person is REALLY anal they can ask you to prove that the serial #s of all the tools on your register match those you are bringing on site - good luck arguing you should get paid for this.
So yeah having 3max chargers to get PAT tested every 6 months is a piece of piss.
