100%, I am a huge fan of actual detachable batteries and I also store most electronics with them removed. I generally consider any rechargeable battery a risky thing to store. (Some explode.)

One thing I really love is power tool systems though: I have some Ryobi tools that are over 20 years old and they work with batteries sold in stores today. (The battery tech has changed but as long as your charger is for your battery tech, the tools are all good.) I rarely use a given tool enough to justify replacing batteries in it every 2-4 years, but I use one of my Ryobi tools or the other frequently enough to justify keeping a couple good batteries available at any given time.

I have a modern drill and impact driver because I use them a lot. But the handful of couple decade old saws are plenty adequate for the very rare occasions I need a jigsaw, circular saw, or sawzall.
