Choosing for your project
Reserve and audio applications require charging-system and sustained-load planning. Do not assume an audio wattage rating establishes compatibility with your alternator or runtime.
Confirm approved mounting location, temperature limits and charging settings for this exact model before installation. AGM-equivalent capacity and cranking ratings are comparison values and are not actual lithium amp-hours.
