Alkaline batter-ies can rupture at high temperatures. External power can only be applied using the GARMIN Auto PowerAdapter or PC Interface Cable with Auto Power Adapter. These cables contain a 12 Vdc to 3 Vdc voltageregulator. Modifications or other applications voids the product warranty.4Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium batterieswhen operating the eTrex Legend in below-freezing conditions. Extensive use of screen backlighting and theelectronic compass significantly reduces battery life. Different brands of batteries vary in performance.Specifications
