Work in a Fire Safety Department and we have recieved this message from a colleague
The occupier had been alerted by popping noises coming form the kitchen. The lithium batteries for his new bike lights had been placed on charge on the work surface in the kitchen. There must have been a fault with either the batteries or more likely the charger as they overheated to a point were the batteries began to explode. The explosions were very short lived and only caused a small amount of superficial damage to the work top and floor.
The owner was going to post on a forum and contact the manufacturer just though I'd post on here in case he's not on this forum.
Not saying it will happen to them all and this may just be an isloated case just be aware and never leave batteries on charge when you go out. Probably a good idea to use a tin to charge the batteries in just in case (I do with my mine)
