Lithium-ion batteries are the rechargeable batteries found in a wide range of electrical items, such as e-scooters and e-bikes, mobile phones and laptops.

They pose a particular risk when charging, so it is important to know how to use them safely.

Lithium Batteries

In recent years, the number of fires caused by lithium-ion batteries has rapidly increased. In the last three years, over 70% of these incidents involved a charger. Follow the advice below to reduce your fire risk.

Always use a charger supplied with the device or recommended by the manufacturer.

Charge the device on a flat, solid and stable surface.

Only charge the device for the recommended charging time and don’t leave unattended – e.g. overnight while you’re asleep, or if you go out.

Keep the device away from flammable materials when charging.

Never charge lithium-ion batteries on your escape route. If possible, charge and store them away from your living areas.

Image6

Avoid storing, using, or charging batteries at very high or low temperatures.

If the device has not been used for quite some time, be extra careful when you charge it – lithium-ion batteries don’t like being discharged to a very low voltage.

Protect batteries against being damaged – that’s crushed, punctured, or immersed in water. Do not use if it looks physically damaged.

Be aware of the dangers

These batteries are safe during normal use, but present a fire risk when over-charged, short-circuited, submerged in water or damaged. They are a main cause of waste fires, and can be extremely dangerous when thrown away with general rubbish, or mixed with other recyclable materials like card, metals and plastics.

Batteries can be damaged by dropping them or crashing e-bikes or e-scooters. Check your battery regularly for any signs of damage and if you suspect it is, it should be replaced and should not be used or charged. Where the battery is damaged, it can overheat and catch fire without warning. These fires quickly spread and are difficult to extinguish, causing widespread damage.

 

How to stay safe

  • Always read the safety instructions that came with your device.
  • Ensure you have working smoke alarms.
  • Always use the charger that came with your device.
  • If you need to buy a replacement battery or charger, always choose a branded, genuine product from the manufacturer. There are lots of fakes out there, and it can be difficult to spot the difference.
  • Charge the device on a flat, solid, and stable surface.
  • Never charge lithium-ion batteries when you are sleeping, or if you are leaving the home.
  • Never charge lithium-ion batteries on your escape route. If possible, charge and store them away from your living areas.
  • If the device has not been used for quite some time, be extra careful when you charge it – lithium batteries don’t like being discharged to a very low voltage.
  • Don’t leave items continuously on charge after the charge cycle is complete – it’s best not to leave your phone plugged in overnight for example.
  • Never cover chargers or charging devices – that includes using your laptop power lead in bed.
  • Protect batteries against being damaged – that’s crushed, punctured, or immersed in water. Do not use if it looks physically damaged.
  • Avoid storing, using, or charging batteries at very high or low temperatures.
  • When you travel, avoid keeping all your items containing lithium-ion batteries together, especially on a plane. Check with your flight carrier for additional information or advice.

E-scooters and e-bikes

Whether you’re cruising around on an e-scooter or e-bike, it’s no secret that it’s an easy, fuss-free way to get from A to B. While we know they are increasingly popular, it is important that when charging e-bikes and e-scooters, you do so safely to avoid a risk of a fire in your home.

  • Buy e-scooters, e-bikes, chargers and batteries from reputable retailers.
  • Many fires involve counterfeit electrical goods. Items which don’t meet British or European standards pose a huge fire risk and while genuine chargers (or battery packs) may cost more, it’s not worth putting your life at risk and potentially destroying your home by buying a fake charger.
  • If buying an e-bike conversion kit, purchase from a reputable seller and check that it complies with British or European standards. Take particular care if buying from online auction or fulfilment platforms. Also be aware that if buying separate components, you should check that they are compatible.
  • Register your product with the manufacturer to validate any warranties – batteries are usually included in warranties. Registering makes it easier for manufacturers to contact you in the event of safety or recall information.
  • Check any products you have bought are not subject to a product recall. You can do this buy checking Electrical Safety First’s website or the government website.

Enjoy and ride your e-bike or e-scooter safely and ensure you are using these products within the law. Further information can be found here https://www.gov.uk/electric-bike-rules and here for e-scooters.

 

Batteries don't belong in bins

  • Never put batteries in your general rubbish bin or with other recyclable materials like card, metals and plastics.
  • Follow instructions from your local council and always keep electrical items separate from other household waste.
  • Sell or donate working, but unwanted, battery-powered electronic items instead of throwing them away.
  • If you can safely remove a battery from a product, the battery should always be recycled separately using a battery recycling point or collection service.
  • If you cannot remove a battery from an electronic product that no longer works, the product and the battery should be recycled together using a waste electricals recycling service.
  • If in doubt, always take unwanted electrical items or lithium-ion batteries to your local household waste recycling centre.
