Both of these batteries are great.

The 2.5 has noticibly more power than the standard 4.0 and 6,0

Why is the 2.5 better than the 5?

Not better I just prefer the smaller form factor to run on my m12 ratchets.

For what it's worth, I know this is a deal on legit milwaukee m12 batteries. I picked up a 2 pack of m12 "compatible" batteries that claim 4 ah for $5 on Amazon haul last week. I haven't done extensive testing,but I did pop them both on my m12 ratchet to confirm that they do indeed work. $5 for 2 batteries that power an m12 tool is tough to beat even if they only had 1/3 the capacity.
