These feature Lithium Iron Disulphide technology, which is a nominal 1.5V system that retains the advantages of lithium but has a voltage compatible with equipment designed for traditional primary cells. They are typically used in GPS and digital cameras and other emergency equipment.
They have a low self discharge of 2% per annum and so will retain good capacity even after 10 years storage. They are also very suitable for ‘standby’ long-term applications. Their superior performance at low temperatures make them ideally suited for use in outdoor equipment used in cold temperatures. Their greater storage capacity means that they will outlast equivalent alkaline batteries by up to 7 times.
