Battery Safety

Battery Safety

Batteries power many of our everyday electrical items, making life more convenient, but if misused they can cause a serious fire risk.

There are two main types of batteries:

Rechargeable batteries (often lithium-ion) - Found in phones, e-bikes, e-scooters, mobility scooters, laptops, vapes, and power tools. They’re generally safe when used correctly, but misuse can lead to serious fire risks
Single-use batteries - Used in items like watches, remotes, toys, and smoke alarms. These are generally lower risk but can still cause fires under certain conditions

To minimise the risk of a battery fire, follow our advice.

Using and charging rechargeable batteries

Always follow the manufacturer’s instructions for using, charging, storing, and disposing of rechargeable batteries.

Only use the charger that came with the battery. Using the wrong charger can lead to the battery overheating and a fire starting.

Buy replacement batteries and chargers from reputable sellers and check for a UKCA or CE safety mark.

Never leave a charging battery unattended or leave it charging when you go to bed. if a fault occurs you need to be alert to it.
Charge on a hard, flat, heat-resistant surface, away from extreme heat, cold, direct sunlight, and flammable materials.
Never cover batteries while charging. This can cause overheating and start a fire.
Don’t overcharge. Always unplug the charger when its finished charging.

Never charge batteries near exits, hallways, or sleeping areas. These areas must remain clear to allow safe and quick evacuation if a battery fire starts.

Battery protection

Never modify or tamper with batteries.
It is damage to batteries that creates fire risk.
To prevent damage avoid dropping, puncturing, or exposing batteries to water. Damaged batteries are a fire risk.

Regularly check for signs of damage like swelling, leaks, or strange smells. Stop using damaged batteries immediately.

Safe storage

Store large rechargeable items like e-scooters, e-bikes, mobility scooters and power tools, in a garage or shed, away from flammable materials and escape route exits.

Always store single-use batteries in their original packaging and away from metal objects. Contact with metal can cause overheating and a fire.

Always store batteries out of reach of children and pets.

Safe disposal

Follow the manufacturer’s disposal instruction. Some offer recycling services.

Never throw batteries in general waste or recycling bins - they can ignite if crushed or punctured.

Check if local supermarkets, electrical retailers, or workplaces have battery recycling points.

When in doubt, take batteries to your local household waste recycling centre (the tip).
