Safety tips for lithium-ion batteries
Lithium-ion batteries power so many devices that we use every day, from smartphones and laptops to electric vehicles and power tools. Favoured for their high energy density, lightweight design, and power consistency, lithium-ion batteries have revolutionised the way we use technology.
However, like any product, a small number of these batteries can be defective and can overheat, catch fire, or explode. Lithium-ion batteries can also be particularly dangerous when used and stored improperly.
More and more accidents involving lithium-ion batteries are being recorded around New Zealand, including a fire caused by a charging e-scooter and a lithium-ion battery from a drill spontaneously combusting. To help you prevent these kinds of accidents from occurring, we’ve put together a few key safety tips to keep in mind when using lithium-ion batteries.
1. Purchase genuine batteries
Always purchase genuine lithium-ion batteries from reputable manufacturers or authorised retailers. That way, you know exactly where the battery has come from, and you know it has been designed to be used with the device it comes with.
2. Store them properly
Lithium-ion batteries should be stored in a cool, dry place away from direct sunlight. Do not leave them in places that experience extreme temperatures, such as a hot car or a freezing outdoor shed. You should also ensure that your devices and batteries are stored on a non-flammable surface.
3. Be mindful when charging
Make sure that the charger you’re using for your lithium-ion battery or device is genuine and fit for purpose. Avoid leaving your batteries sitting on the charger for long periods of time, as they could overcharge and overheat.
4. Handle batteries properly
Always be careful when handling lithium-ion batteries. Avoid dropping, puncturing, or crushing them, as this can damage their internal structure and cause a major fire hazard. You should also check your devices and batteries regularly for signs of swelling or leakage.
5. Dispose of them correctly
Lithium-ion batteries and devices should never be thrown out in your usual rubbish or recycling collection. If you need to dispose of any lithium-ion batteries, take them to a dedicated recycling service or hazardous waste drop-off point. Contact your local council for locations like these in your area.
6. Put safety first
If you notice your battery swelling, smoking, or overheating, turn off the power (if it’s safe to do so) and move the device away from any flammable materials, ideally outside. Of course, if your battery or device poses an immediate risk to your safety, leave the situation immediately and dial 111.
