Lithium-ion batteries are used in e-bikes, mobility scooters, e-scooters, phones, tablets, laptops, cameras and e-cigarettes. If damaged, faulty or charged incorrectly, they can start fires very quickly. Most battery fires happen in people's homes and often while batteries are charging.
Charge batteries safely
To charge lithium-ion batteries safely:
- charge batteries on a hard, flat surface where heat can escape – use laptops on hard surfaces, not on bed or sofas
- never charge batteries in communal areas
- use only the charger designed for your battery or device
- buy replacement batteries and chargers from reputable sellers
- avoid counterfeit products and unapproved universal chargers
- do not leave batteries charging overnight, while you are asleep, or when you are out
- unplug chargers once batteries are fully charged
Do not store e-bikes, mobility scooters, or e-scooters in communal areas, hallways, stairwells, or escape routes.
Warning signs of a faulty battery
Stop using and charging a battery if you notice:
- it becomes unusually hot
- it swells, bulges or leaks
- it makes hissing, popping or cracking noises
- it gives off a strong or unusual smell
- it takes much longer to charge or does not fully charge
If a battery starts smoking or catches fire, leave the area immediately, raise the alarm and call 999.
E-bike conversion kits
E-bike conversion kits turn non-electric bikes into electric bikes. Make sure you:
- buy conversion kits from reputable sellers
- use the correct charger
- never alter or tamper with a battery
- have e-bike conversions carried out by a qualified professional
Second-hand batteries
Avoid second-hand batteries, as they may already be damaged and could fail without warning.
Disposing of batteries
Never put lithium-ion batteries in household waste or recycling bins. Take them to a battery recycling point or Household Waste Recycling Centre (HWRC) where they can be disposed of safely.
