In about 2010 I got a Bosch rechargeable drill kit with two batteries. The batteries are still in use, but the drill has been changed as the hammer function stopped working.
The new drill is smaller, lighter and the chuck goes up to 13 mm instead of 10 mm and it's brushless and it takes the same batteries.
I have several other tools that take the same batteries. I think that the list is a hedge trimmer, garden blower, strimmer and a sander.
Today SWMBO got a vacuum cleaner that takes the same battery type, and it was the first item since the original kit that contained a battery.
The battery is smaller (45 mm tall as opposed to 55 mm tall) and heavier (375 g vs 330 g) and it doesn't have the ability to be charged from underneath. It is also twice the nominal capacity of the old ones. I am quite impressed by the fact that Bosch had stuck to the same standard* and have improved the battery capacity so much.
*The micro chainsaw, and the lawnmower, also Bosch, have different batteries.
