· 5 min read
Draft — placeholder content. Not yet reviewed for publication.
Battery makers often ask which certificates they really need for Europe. The short answer: it depends on the battery, but most lithium packs need a mix of transport, safety and market requirements.
UN 38.3 — to ship at all
UN 38.3 is a set of transport tests for lithium cells and batteries. Without a UN 38.3 test summary, airlines, shipping lines and freight forwarders will not move your batteries. You also need an MSDS.
IEC 62619, IEC 62133 and EN 50604-1 — to show the battery is safe
- IEC 62619 covers industrial lithium batteries, including home storage and BESS.
- IEC 62133 covers portable sealed cells and batteries.
- EN 50604-1 covers batteries for light electric vehicles such as e-bikes and e-scooters.
CE marking — to sell in the EU
Under the EU Battery Regulation, batteries carry CE marking. Your test reports are the evidence behind it.
The battery passport — from 18 February 2027
On top of all this, EV, LMT and industrial batteries above 2 kWh need a digital passport.
