Are household batteries safe?
Most household batteries are lithium-ion batteries. Lithium-ion batteries have high performance, long lifetimes and low maintenance needs.
Leading brands include built-in safeguards that prevent overheating, overcharging, and electrical faults. When choosing a home battery be sure to look only at reputable battery products certified according to recognised safety standards and be sure to deal with an installer licensed by the Clean Energy Council to ensure a safe installation. Cheaper or lower quality batteries may not be designed to withstand Australia’s extreme weather conditions. You can check out installers’ own ‘best brands’ rankings here.
It's rare for household batteries to cause fires. The vast majority of lithium-ion battery incidents involve smaller consumer electronics like e-bikes and smartphones. The only exception is in relation to LG home batteries. These were recalled in 2023 due to their fire risk. If you have an older battery and are concerned about its brand, you should contact LG Energy Solution Australia (LG). Further information is available at the Product Safety Australia website.
