Alkalinebatteries can rupture at high temperatures. External power can only be applied using the GARMIN AutoPower Adapter or PC Interface Cable with Auto Power Adapter. These cables contain a 12 VDC to 3VDCvoltage regulator. Modifications or other applications will void the product warranty.4Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithiumbatteries when operating the eTrex Mariner in below-freezing conditions. Extensive use of screenbacklighting will significantly reduce battery life. Different battery brands vary in useful life.
