Well we're in luck, because the regulation does touch on this.
Batteries must be "available as spare parts of the equipment that they power for a minimum of five years after placing the last unit of the equipment model on the market, with a reasonable and non-discriminatory price for independent professionals and end-users"
And there's a ban on software-locking too: "Software shall not be used to impede the replacement of a portable battery or LMT battery, or of their key components, with another compatible battery or key components."
