The big manufacturers (specifically, the ones listed by OP) change their battery connectors and voltages every 10 or so years in order to re-patent the shapes to make them the sole suppliers of usable batteries. People that work on job sites need batteries that are intrinsically safe and robust enough to get thrown around or smashed by other heavy tools. So those packs have to be really overbuilt.
Luckily the major design patents are about to run out and a third party will swoop in and free us from the tool manufacturer battery tyranny.
I used to have their card just for gas. But I sold my truck and have an EV now. Maybe it’s time to close that account because costco is truly a detriment to my after tax take home pay.
Except their premium canned peanuts. God those are good. The stuff at the grocery store is always stale and 4x the price per weight.
