Which battery certification you need depends on two things: what the battery powers and where you sell it. Almost every lithium battery needs UN38.3 to be shipped. Most portable batteries use IEC 62133-2 as their safety standard. North American buyers often also ask for UL 2054. Batteries for e-bikes and scooters fall under UL 2271, and batteries for larger vehicles such as ride-on forklifts fall under UL 2580.
Key Takeaways
- UN38.3 is a transport requirement, not a product safety approval. You need it to ship.
- IEC 62133-2 covers portable sealed secondary lithium cells and batteries, and is the usual basis for CB scheme reports.
- UL 2054 covers household and commercial batteries. UL 2271 covers light electric vehicle batteries. UL 2580 covers EV and industrial vehicle batteries.
- The device itself may need its own standard, such as IEC 62368-1 or IEC 60601-1, which also looks at the battery.
Quick Comparison of Lithium Battery Standards
| Standard | Scope | Typical products | Main market |
|---|---|---|---|
| UN38.3 | Transport tests for lithium cells and batteries | All lithium batteries | Global (air, sea, road) |
| IEC 62133-2 | Safety of portable sealed secondary lithium cells and batteries | Consumer electronics, tools, wearables, medical | Global / CB scheme, EU, Asia |
| UL 2054 | Household and commercial batteries | Portable consumer and commercial packs | USA / Canada |
| UL 2271 | Batteries for light electric vehicles (LEV) | E-bikes, e-scooters, e-motorcycles | USA / Canada |
| UL 2580 | Batteries for electric vehicles | Ride-on forklifts, golf carts, EVs | USA / Canada |
| IEC 62368-1 | End-product safety for AV and ICT equipment | Laptops, speakers, power banks, cameras | Global |
UN38.3: Required to Ship, Not a Safety Mark
UN38.3 is a series of transport tests defined in Section 38.3 of the UN Manual of Tests and Criteria. The eight tests (T1–T8) simulate altitude, temperature cycling, vibration, shock, external short circuit, impact, overcharge and forced discharge. Manufacturers and distributors must make a UN38.3 test summary available to their customers.
Passing UN38.3 shows the battery can be transported safely. It does not certify the battery as safe in use. See our full guide to UN38.3 certification.
IEC 62133-2: The Global Baseline for Portable Batteries
IEC 62133-2:2017+AMD1:2021 sets requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries, both in intended use and in reasonably foreseeable misuse. It is the standard most often used for CB test reports, and many countries accept those reports for national approvals.
Choose IEC 62133-2 when your pack goes into a portable device sold in the EU, Asia or several markets. We look at pack configuration under this standard in IEC 62133 and 4S2P configurations.
UL 2054: Household and Commercial Batteries in North America
UL 2054 covers portable primary and rechargeable batteries. It aims to reduce the risk of fire or explosion both when the battery is in use and when it is removed for transport, storage or disposal. US retailers and OEM buyers often ask for it. The US FDA also recognizes UL 2054 as a consensus standard for medical devices (UL Solutions).
UL 2271 vs UL 2580: Which Vehicle Standard Applies?
The dividing line is the type of vehicle:
- UL 2271 covers battery packs for light electric vehicles, such as e-bikes, e-scooters and personal mobility devices. It explicitly excludes on-road passenger EVs and ride-on industrial trucks.
- UL 2580 covers batteries for electric vehicles. According to UL Solutions, that includes ride-on forklifts, ground support equipment, golf carts and motorcycles.
Stationary energy storage uses a different standard again (UL 1973). Our guide to golf cart and forklift lithium conversion covers the vehicle side.
Don’t Forget the End-Product Standard
The battery is tested as part of the finished device, too:
- IEC 62368-1 for audio/video and ICT equipment such as laptops, speakers, cameras and power banks
- IEC 60601-1 for medical electrical equipment. See our medical device battery guide.
A pack that already has IEC 62133-2 or UL 2054 usually makes end-product approval quicker, because the lab can rely on the existing battery report.
EU Market: The Batteries Regulation
Batteries sold in the EU must also comply with Regulation (EU) 2023/1542, which covers safety, labelling, sustainability and end-of-life. Two dates matter to designers:
- From 18 February 2027, portable batteries in products must be removable and replaceable by the end user (Article 11).
- From the same date, LMT batteries and industrial batteries over 2 kWh need a digital battery passport.
Which Certifications Do You Need? A Quick Guide
| Product and market | Typical certification set |
|---|---|
| Consumer device, EU | UN38.3 + IEC 62133-2 + end-product CE + EU Batteries Regulation |
| Consumer device, USA | UN38.3 + UL 2054 or IEC 62133-2 (as the buyer requires) + end-product listing |
| E-bike / e-scooter, USA | UN38.3 + UL 2271 (often with UL 2849 for the whole e-bike) |
| Golf cart / forklift, USA | UN38.3 + UL 2580 |
| Medical device | UN38.3 + IEC 62133-2 + IEC 60601-1 at the device level |
Frequently Asked Questions
Does a CE mark cover the battery?
CE is a self-declaration against the EU directives and regulations that apply. For lithium packs, most manufacturers back that declaration with an IEC 62133-2 test report.
Do I need both IEC 62133 and UL 2054?
Only if you sell in both regions and your buyers ask for both. Test one frozen design for both standards at the same time to save cost.
Do I need new certification if I change cells?
Usually yes. A new cell model can invalidate UN38.3 and safety reports. Check with your lab before switching.
