Insurer Aviva Issue Lithium-Ion Battery Fire Concerns

Insurer Aviva have issued a warning to their customers after seeing a 7% increase in claims relating to lithium-ion battery fires over the past year.

The insurer commissioned research which reveals one in nine Brits have experienced a fire or explosion in their home due to a lithium-ion device.

Aviva’s research also advises that 43.2 million people in the UK own a device with a lithium-ion battery, and awareness around what a lithium-ion battery is and the charging risks they possess is also low – 41% wouldn’t know how to identify a lithium-ion battery and 42% unaware of the fire risks when charging one.

While this research gives statistics with regards to incidents in the home, here at CHSG we feel the safety principles trained on site shouldn’t necessarily stop once you head home – only 23% of people asked could identify there was a lithium-ion battery in a power tool.

How to Identify a Lithium-Ion Battery

Lithium-ion batteries can be rechargeable or non-rechargeable (known as primary batteries).

Primary batteries (non-rechargeable) can be found as AA/AAA, C, D, Coin/Button cell, and 9v. Lithium Primary batteries may be marked “Lithium;” button/coin cells may begin with (CR###).

Lithium-Ion batteries may be marked “Rechargeable,” “Lithium Ion,” “LiION,” “Li-ion,” “Li-Ion”, “LiPo” (lithium polymer); button/coin cell begins with (LIR###). They may or may not have a battery seal or other mark.

Safe Lithium-Ion Battery Charging (Aviva Advice)

  • Always use manufacturer-approved chargers specifically designed for the device.
  • Avoid overcharging the battery.
