- PCWorld highlights six vital battery charging errors that may result in harmful thermal runaway fires, affecting gadgets from smartphones to e-bikes.
- Frequent errors embody utilizing low-cost chargers, charging on gentle surfaces, in a single day charging, and ignoring broken cables or overheating gadgets.
- In case of battery fires, instantly evacuate on account of poisonous fumes, use water for small batteries, and sand or specialised fireplace blankets for bigger ones.
A cell phone battery shops monumental quantities of vitality in a really small house. So long as all the things is working correctly, we don’t discover something. However a technical defect or incorrect dealing with can set off a sequence response — referred to as thermal runaway. This causes the battery to gas itself with vitality till it bursts into flames or ruptures underneath intense stress.

Don’t stand round to look at the spectacle – batteries can nonetheless launch extremely poisonous aerosols 20 minutes after the flames have gone out.
- The best extinguishing agent: For small lithium-ion batteries (e.g. in smartphones), loads of water is usually appropriate for cooling to cease the chain response. Opposite to what’s generally claimed, lithium-ion batteries don’t react like pure metallic lithium, which instantly types extremely explosive hydrogen fuel and burns violently when it comes into contact with water. Vital: By no means throw the battery right into a small container with a bit water – the fast improvement of fuel may cause a harmful deflagration.
- Sand, salt, or fireplace blanket: These brokers serve to smother the flames and stop them from spreading to the encompassing space. Vital to know: A battery fireplace can hardly be smothered within the conventional manner as a result of the battery itself releases the oxygen for the chemical response inside.
