Batteries are a point of vendor lock-in and forced obsolescence. Not saying modern tech isn’t great, but young me who spent all that money tooling up with cordless has changed to older me who honestly prefers corded or hosed (or even ICE) tools when the application allows for it, not just for the longevity of the tool but the power (amps/psi), lighter weight, and availability of service (no issues with charging, temperature problems, etc) during a job.
