 The Battery Regulation (EU 2023/1542) is the first product-group regulation to require a Digital Product Passport in production. Article 1(3) applies it to five categories of battery, and only five: portable, starting-lighting-ignition (SLI), light means of transport (LMT), electric vehicle (EV) and industrial. The list is closed on purpose: where a battery could fall under more than one category, the strictest requirements apply, and that rule only works over a closed list. Stationary energy-storage systems are not a sixth category; the Regulation places them under industrial. The regulation is already in force, and some of its staged dates have already passed.
 
 ## Which batteries need a passport
 
-Not all five. **Art. 77(1)**: from 18 February 2027, each LMT battery, each industrial battery with a capacity greater than 2 kWh and each electric-vehicle battery placed on the market or put into service must have a battery passport. Portable and SLI batteries, and industrial batteries of 2 kWh or less, do not. Under **Art. 77(8)** the passport ceases to exist once the battery has been recycled.

 - **Declared now, binding later**: the minimum recycled-content shares for cobalt, lithium, nickel and lead, set by Art. 8(2) and 8(3) and cross-referenced to Annex VIII. (Annex X is the due-diligence raw-materials list and has nothing to do with recycled content.) These are final law but only take effect in 2031, rising again in 2036, so today they are shown as advisory rather than as a pass or fail.
 - **Waiting for a delegated act**: minimum electrochemical performance and durability values, empowered by Art. 10(5), and the carbon-footprint performance class under Art. 7(2). Art. 7(2) requires the label to declare a class but leaves the classes themselves to an act that has not been adopted, and requires the scale to be revised every three years. Neither the classes nor how many there will be is settled, and we do not guess.
 
-The passport itself becomes mandatory on **18 February 2027**. As each later requirement takes effect, the battery checks are extended to cover it, and passports already issued stay valid. Every product group follows the same approach of giving a binding verdict only where the law applies; see [ESPR Overview](/regulatory/espr).
