Re: Got 4Ah, not 5Ah, battery 18V (20V) - done right thing?

I found in a lot of cordless tools the higher amp hour rated battery the better.  Generally I have not noted it for light load tools like a cordless drill using small bits, but things like electric chainsaw, angle grinder, etc it was very noticeable.  I do not mean just that the bigger AH rating ran longer.  I mean it delivered more current in a short fixed time period.  The tool performed better.  I've experienced this with relatively cheap lines like Harbor Freights Bauer line and with better pro and pro-sumer cordless tools like Milwaukee and DeWalt. If you follow the YouTube channel "The Torque Test Channel" they mirror this result with more subjective data across a range of tools including drills and impact wrenches.
