Originally posted in connection with the rechargeable batteries that I use in various devices and power tools etc. but also very applicable to the high-capacity Li-Ion type e-scooter/e-bike batteries. Never leave these unattended whilst charging and always store these outdoors and away from yours and surrounding property as some seem to have a very nasty habit of catching fire like the one recently in the news which burnt down eight terraced houses!. I believe that there are a lot of cheap and unsafe batteries around for these scooters. I take battery charging and storage very seriously and I would more than strongly advise that you also do so. I am always particularly warry about cheap Chinese manufactured batteries, mains chargers and power supplies, one of the user manuals for a Chinese radio with a rechargeable battery contained the following alarming phrase “if are smoke and flame switch off”, hardly inspires confidence does it!.

Kind regards Leigh
