FAULTY batteries in e-cigarettes could cause fires this Christmas, according to trading standards teams.

Consumers are being warned by Worcestershire Regulatory Services to be alert when purchasing products, as

recent testing has identified devices with batteries that do not have a charging cut off.

This means that the batteries will continue to charge after reaching full capacity, which could lead to overheating and produce an ignition source.

Worcestershire Regulatory Services is urging members of the public to only by from reputable sources, ensure the e-cigarette carries a CE mark and to never leave devices charging unattended for long periods.

A spokesperson for Worcestershire's trading standards teams said: “We are concerned about the quality of some of these e-cigarettes and chargers that are on the market place, which is why we have undertaken some testing.

"The results did confirm our fears that some of these products are unsafe.

"However, if you follow manufacturer’s advice and our top tips, you significantly reduce the risk of a fire.”

Councillor Bronwen Behan, joint committee chairman at Worcestershire Regulatory Services, said: “Our trading standards officers strive to keep consumers safe and are determined to remove unsafe products from the market place.

"I am pleased that we have been able to highlight these safety issues to Worcestershire residents.

"Simple checks can avoid a Christmas disaster so please stay cautious.”
