Swapping a forklift battery is a maintenance task, not an operational/ process task.
NET: it could be done.
There is no f'in way manufacturers will agree to the same battery as everybody else.
now you'll also need batteries for model years in each of the manufacturers vehicles..i.e. a 2021 Hundai uses a different battery than a 2022 Hundai would, etc...
the battery swap seems like a logistical nightmare
