They're fairly expensive, but there's a modern version of this which you hang above possible ignition sources or throw into a new fire: https://www.amazon.com/4PACK-Extinguisher-Bracket-Portable-Extinguishing/dp/B0C538CQFX
After getting one for grow lights I started putting them around the house to be able to quickly smother a fire anywhere. That model covers anything except Class D metallic fires (edit: ABC Dry Chemical isn't rated for class K oil fires either), but if I had a lithium ion battery indoors I'd absolutely be hanging a Class D-specific model above it.

I hope you are not relying on those exclusively.
Not exclusively. I have the point-and-spray kind as well.
