If it had (2) 4ah batteries, maybe.
The 'newer' battery is not some special deal.
Read about battery cell size here:
https://www.sciencedire
21700 cells do have better energy density than 18650 ones..theoretically 6%. In the real world its about 2%. That 2% matters when you are packing thousands of cells into an EV. For about a dozen in a tool battery pack? Meh.
Don't get fooled by a battery pack being shorter. Its also wider and deeper. Maybe you like the dimensional change. It does make a tool stand on end better. That's fine. Personally, I'm indifferent. Give me the most amp-hours for the least money.
Cell QUALITY is what really matters, not cell size.
Manufacturers can introduce other improvements in newer battery packs (better cooling, security features, displays, whatever) and those might be worth paying for..
Just don't confuse a larger cell size with automatically being a better choice.
