Exactly the 18650 link can be purchased for PLN 8 new and there are also those that cost more than PLN 50. The higher shelf has an additional number of safeguards, e.g. when the drill is blocked in metal, it can cut off the momentary seeding only so that the cells do not get hurt in the butt, giving off a very high short-circuit current. The second issue of durability is the charger, which, despite fast charging, does not damage the cells, shortening their lifetime.
By the way, these "free 18650 cells" are even suitable for powetbank, not to mention screwdrivers, unless for a small battery screwdriver with a small current. Regeneration of screwdriver batteries is not cheap, as some people think, but it is profitable because, depending on the brand, it costs 50-70% of a new battery.
One more question of parameters, I personally do not trust the Nm numbers with the cell capacity nowadays, there are also different reviews on the Internet, the original 2.0Ah battery and inside the 1.3Ah cell there are also reverse situations, I write less than I really saw something like this, probably in the metabo or makita.
