A Public Service announcement
All your drill batteries will be almost dead when you start a project. Both will make the drill spin when you test them out, but they'll both be dead in an hour.
Gotta use the batteries regularly. If you don't they will lose their efficiency. NiCad was real bad about it, lithium ion is a lot better but they will too. AND FOR THE LOVE OF GOD DO NOT TRUST LITHIUM BATTERIES UNATTENDED!!! I've had two lithium batteries burn up in my pocket. The first time was a Chinese flashlight from Amazon. The second time was a Sonim ruggedized flip phone. Several years ago there was some planes that had an issue with lithium batteries I believe.
I keep mine on chargers that are plugged into timers. The timers will charge the batteries for about two hours each day and then shut off. Setting things up this way will keep the batteries topped off but won't allow them to heat up. I get around five years out of my rechargeables this way. I also cycle them through the equipment they power so that all see around the same amount of use.

That's why I went back to my plug in tools. And I don't have to replace batteries every few years cause they've gone bad lack of use.
This is a law of nature, a direct corollary of Murphy's Law. As inviolable as Ohm's Law or Thermodynamics.

In a similar way having four 20 pound LP cylinders for the gas grill is not much help if you have four empty cylinders.
And the drill bit set will only be missing the one drill bit you need for the project.
Keep your plug in drills, I'll gladly replace my battery powered ones every 5 or so years
4" grinders, now that's a different story
Same for sanders
Upgrade to newer models, most have the battery level lights on them today.
