IT is free money in another way for manufactures as well: since they battery doesn't have to sit in their factory/fixtures for as long getting that initial charge there is a lot less in process batteries in their factory, less charging fixtures and jigs to buy... This process savings is often invisible until an accountant looks close and then they discover it is massive.

Yup, batteries can leave the production line and be put into storage for distribution an entire shift earlier.

If you've got your widget rolling off the production line once every 90 seconds, you only need 14 chargers to have the charging done just in time on the line itself, eliminating the "storage for distribution" step entirely.

That sounds like a minor details, but accountants keep poking at that and discovering that extra steps like that are cost a lot of money. I'm guess tens of millions more $$$ which either goes to more profit or lowering prices - either is good (profit because I may be an investor, lower prices for customers)
