Protecting Against Lithium Batteries

Increasing Vigilance and Safety Measures

As the popularity of electric vehicles and portable devices powered by lithium-ion batteries continues to rise, so does the concern over safety. Recent reports indicate a significant increase in lithium-ion battery fires, with a staggering 150% surge in incidents by September 2022 compared to the previous year. These fires have struck not only electric cars but also smaller vehicles like e-scooters and e-bikes. Some incidents have been linked to unsafe conversion kits and non-compliant batteries purchased online.

Recognizing the Danger

Lithium-ion batteries can generate toxic gases and ignite fires or explosions when damaged or overheated. Identifying warning signs can save lives. If your device or vehicle shows any of the following, take immediate action:

  • Heat: Excessive heat during charging or use may indicate a defective battery.
  • Bulging: A swollen or misshapen battery is a clear sign of trouble.
  • Noise: Strange hissing or cracking sounds from the battery.
  • Smell: Unusual or strong odors coming from the battery.
  • Performance: Longer charge times or a failure to charge fully.

If you notice any of these signs, shut off the device, unplug it, and contact the manufacturer or retailer promptly. Following these steps reduces the risk of a catastrophic fire.

Reducing the Risk

To improve the safety of your e-bike or e-scooter charging practices, follow these measures:

  • Stay Vigilant: Be on the lookout for signs of battery failure.
  • Avoid Unattended Charging: Never leave your battery charging while you are away or sleeping.
  • Check for Safety Standards: Ensure your battery and charger meet UK safety standards.
  • Let It Cool: Allow the battery to cool before charging.
  • Unplug After Charging: Once the battery is fully charged, disconnect the charger.
  • Install Smoke Alarms: Place smoke alarms in areas where you charge your batteries.
  • The Chartered Trading Standards Institute also warns against purchasing non-compliant devices, urging consumers to:
  • Buy from Reputable Retailers: Purchase e-bikes, e-scooters, chargers, and batteries from trusted retailers.
  • Avoid Counterfeit Products: Do not buy counterfeit batteries or chargers and ensure devices display a valid UKCA or CE mark.
  • Check Compatibility: Confirm that separate components, such as batteries and chargers, are compatible.
  • Register Products: Register your products with the manufacturer to validate warranties and safety recalls.
  • Verify Recalls: Ensure that your purchases are not subject to a product recall by checking Electrical Safety First’s website.

Additional Risks and Proper Disposal

Lithium-ion batteries pose other risks beyond personal safety:

  • Maintenance workers: People handling high-voltage lithium-ion batteries risk electric shock or fire when dealing with damaged batteries. “Stranded” energy in damaged cells can reignite.

  • Safe disposal: Improper disposal causes nearly 700 fires annually in the UK. Lithium-ion batteries should never go in household rubbish or regular recycling. Check your local authority’s website for proper disposal guidelines.


By staying vigilant and following these precautions, we can all help create a safer environment for electric vehicles and devices powered by lithium-ion batteries. This reduces the risk of catastrophic fires and environmental hazards.
