Article 1 covers all categories of batteries, regardless of shape, volume, weight, design, material composition, chemistry, use, or purpose. It also covers batteries incorporated into products, added to products, or specifically designed to be incorporated into or added to products.
A scope review should therefore start with the battery itself, not only the host product. Record whether the item is a cell, module, pack, battery, incorporated battery, product containing a battery, replacement battery, repurposed battery, or remanufactured battery.
For batteries that can fall into more than one category, Article 1(3) applies the strictest category for Chapter II requirements. End-use cells and modules follow the separate Article 1(4) rule: use the most similar category, or the strictest category if more than one applies.
