Safe charging: the habits that prevent most fires

Charging is the danger zone. A handful of simple habits eliminate the majority of avoidable battery fires before they ever start.

Charging is when many lithium-ion fires ignite or first show signs of trouble, which makes it the highest-value moment to get right. Fire and Rescue NSW's "golden rules" for e-mobility safety centre on how, when and where you charge (Mueller & Co, 2026).

The rules worth memorising

  • Always use the correct charger supplied with the device — never mix and match. Incorrect chargers are a leading cause of fires.
  • Never charge unattended, especially overnight or while you're asleep or away from home.
  • Don't modify devices or batteries to increase speed or range.
  • Buy from reputable retailers; avoid cheap online imports that may not meet Australian standards.
  • Keep a working smoke alarm on every level of your home as a minimum.

(Fire and Rescue NSW, 2025; Mueller & Co, 2026)

Charge away from escape routes. Avoid charging near doorways, hallways or on the only path out of a room. Charge on a hard, non-combustible surface — never on a bed, sofa or carpet — and don't cover the device while it charges.

Awareness is still patchy

A NSW Government survey found that while 44% of respondents understood the risks of lithium-ion batteries, many still charged unsafely; 32% said they didn't know how to apply safety measures and 29% were unsure (International Fire & Safety Journal, 2025). Knowing the rules is only useful if you actually follow them.

For an extra layer of protection during charging and storage, a fire-resistant containment bag isolates a battery if it fails, and a nearby fire blanket lets you respond fast. Homes with chargers installed can review options on the home charger safety page.
