IEC 62133-2 Battery Safety for Wearables
1 resources tagged with "Iec 62133 2"
IEC 62133-2:2017 is the lithium-ion specific safety standard required for the small rechargeable packs in wearables like smartwatches and fitness trackers. It pairs with FCC and CE for a US/EU launch and with UN 38.3 for air transport. A US fitness startup in our casework shipped 3,000 smartwatches with FCC + CE dual certification at a 0.6% defect rate — the battery safety chain (62133-2 plus UN 38.3) was the long-lead item that had to start early to hit an investor milestone.
When sourcing wearables, the pouch cell inside is the certification bottleneck. We line up IEC 62133-2 and UN 38.3 in parallel with FCC/CE so battery testing doesn't become the critical path that slips your launch date.

FAQ
What battery certs does a smartwatch need for US and EU sale?
IEC 62133-2 for cell/pack safety, UN 38.3 for air transport, plus FCC (US) and CE (EU) for the wireless and product compliance. All four typically run in parallel to protect the timeline.
How long does IEC 62133-2 take for a wearable battery?
Expect 3–6 weeks at an accredited lab once samples are ready. Start it early — it's commonly the slowest item in a wearable certification plan.
