Unsafe e-bike batteries still in use, safety chief warns

E-bike users are being urged to check their batteries after the Office for Product Safety and Standards (OPSS) renewed warnings about fire risks linked to certain models.

The safety regulator has advised consumers to stop using UPP (Unit Pack Power) battery models U004 and U004-1, stating that they pose a significant fire and explosion hazard.

These batteries have been linked to multiple serious fires, prompting concerns over their continued use.

Graham Russell, Chief Executive of OPSS, said: “Unsafe e-bike batteries are still in use around the country. When they are being charged, they can catch fire with horrific force, threatening the lives of those who use them, their families and their neighbours. While OPSS takes action to remove these wherever we can, it is vital that consumers are aware of the risks and that they check that their own e-bike, or any e-bike they see for sale online, does not contain these UPP batteries. If anyone finds one, don’t use it and contact the seller.”

The warning follows an earlier alert in January 2024, when OPSS required online marketplaces to remove these batteries from sale.

However, concerns remain that many may still be in circulation, particularly in second-hand e-bikes or conversion kits.

Consumers are advised to take the following steps:

• Check whether their e-bike, especially second-hand models or conversions, contains a UPP U004 or U004-1 battery.
• Stop using and charging the battery immediately if they own one.
• Dispose of it safely at a household recycling centre that accepts this type of battery.
• Contact the seller to seek redress.

The Government has also urged consumers to only buy e-bikes from reputable sellers, replace parts with manufacturer-recommended products, and seek professional assistance for conversions or repairs.
