Lithium battery safety: power banks, tools and e-bikes
QUICK ANSWER · START HERE
Follow the device and charger instructions. Stop using a battery with swelling, leakage, unusual heat, odor or noises. If it is smoking or burning, leave the area and call emergency services from a safe place; do not carry it through the home. Keep charging areas away from your escape route.

Build your plan.
- 01
Check your equipment
Use the specified compatible charger and reputable, certified equipment. Do not improvise repairs to a damaged pack.
- 02
Choose a charging place
Keep batteries away from combustible materials, direct sun and hot vehicles. Follow the product temperature limits.
- 03
Notice changes early
Stop using a device with unusual heat, changed shape, leaks, smells or sounds. Seek manufacturer or qualified repair advice rather than opening the pack.
- 04
Dispose through the right service
Do not put lithium batteries in household trash. Ask the local battery collection service how it handles damaged batteries before transporting one.
Make a household charging map
Editorial exercise: list where phones, power banks, tools and mobility batteries are normally charged. Mark any location that blocks a doorway or stair. Move routine charging to a suitable clear area according to the manufacturer; agree who checks that the right charger is used.
Buying backup power
Compare the jobs you actually need a battery to do, cable compatibility, storage instructions and reputable certification information. Record the model and support contact. A larger battery adds cost and storage needs; test the smallest suitable option before expanding.
PLAN AROUND WHAT YOU HAVE
If help is unavailable.
If a damaged battery cannot be assessed promptly, keep people away and avoid using or charging it. Smoke, fire or escalating heat calls for evacuation rather than waiting for a repair appointment.
People & practical needs.
Keep children away from chargers and damaged packs. Include e-bikes and mobility equipment in the escape plan; a battery or vehicle must not block the only exit.
Keep essentials within reach
Model, charger specification, manufacturer contact and a separate flashlight. Keep emergency contacts accessible without the affected device.
Next steps.
Review charging locations, remove incompatible chargers from routine use and ask your local collection service about disposal arrangements.
Ordinary inspection finds damage?
Stop use and arrange qualified advice.
Smoke or fire?
Leave, stay out and alert emergency services from a safe location.
Common questions.
Can I fix a swollen battery?
Do not puncture, compress or open it. Stop using it and seek appropriate handling instructions.
Watch for.
A battery exposed to flooding may need specialist handling. Do not test it by charging. Smoke and fire can make the surrounding air unsafe.
