$10/ah for max output batteries is a standard "good deal."

These are standard output and more expensive. 2x 4.0ah max batteries plus a charger was $75 last week.

A couple months back there was a hack deal where two 4 ahs came out to less than $40. $50 for one isn't special

It's also worth noting that you only get a lifetime warranty on batteries that are part of a kit.

That was true a decade ago, but all batteries are now eligible for the lifetime service agreement.

That was a great deal. It was $36 and change for 2 batteries (4AH), a charger, and maybe even a bag. Wish I could have done it a second time.
It was more than a couple months back, almost a year ago.

The best deals of the year usually hit about late January when they are clearing out their Black Friday special kits. Every once in a while, the stars align and the Free-Tool promo overlaps with clearance pricing. That's what happened to make that very special deal work.
