The service life of a rechargeable battery can be extended with the correct handling: Read the operating instructions carefully. For instance, it specifies the temperatures at which a battery should be charged. Only charge in dry conditions and only with the original charging cable, for example. If you do not want to use your CHIKE for a longer period of time, it is best to store the battery at about 60 percent of its capacity and at a temperature range of 10 to 15 degrees Celsius. Please also observe the manufacturer’s instructions.
