Hazard
The product presents a risk of fire as certain battery cells within affected units may develop internal defects over time. An investigation identified that battery cells manufactured by a third party may contain excessive lithium plating, which can lead to cracking of the cell casing. This may result in an internal short circuit and subsequent thermal runaway, increasing the risk of the battery overheating and catching fire.
The product does not meet the requirements of the Electrical Equipment (Safety) Regulations 2016.
