Derbyshire Fire & Rescue Service offers advice around lithium battery safety
We're being encouraged to take care when charging any new products
People in South Yorkshire and North Derbyshire are being urged to take 'extra care' with batteries over the festive season.
Fire crews warn that leaving Christmas lights on or charging new devices overnight can be dangerous.
Derbyshire Fire & Rescue Service Station Manager Barclay Masterson has this advice around batteries:
"Never put your batteries in your household bin.
"Take them to a battery recycling point.
"Most supermarkets and shops have these.
"Battery fires can destroy properties in minutes and put lives at risk.
"They're very hard to put out because they can re-ignite even after you think they've extinguished.
"So, it's vital that any items that contain large, lithium ion batteries, are charged or stored in areas that don't compromise your escape from your house or flat - should they fail."
