Lithium batteries are becoming increasingly popular for boats, and with good reason. Lithium batteries offer several advantages over traditional lead-acid batteries, such as longer life spans, higher energy density (meaning more power in a smaller package), faster charging times, and improved safety features. In addition to these benefits, they also require less maintenance than their lead-acid counterparts. Despite the increased cost of lithium batteries when compared to lead-acid models, many boaters have found that the long term savings make them well worth it. Not only do they last longer but because of their greater energy density they can often replace multiple standard sized batteries without taking up any additional space on board. With all these advantages combined it’s easy to see why so many boat owners are making the switch to lithium battery technology.
