Lead-acid batteries may fail prematurely due to operating in deficit mode (rarely or never fully charged) or if left partially charged or fully discharged. A lithium-ion battery does not need to be fully charged, with service life even slightly improved by partial charge. This means it is great for heavy duty usage such as liveaboard boats, motorhomes, caravans and off-grid applications.
