Marine Battery

Lithium batteries are much lighter than any lead-acid derived marine battery, one-third the weight of traditional lead batteries.

Intermittent high loads have a discharge capacity of more than 100 amps/hour. They will provide more (up to 10x) charge/discharge cycles over their lifetime than any older technology battery.

The battery plates are covered by stronger plates and sealed calcium additives, resulting in a loss of only 3% of the power per month. This is ideal for boats that don't have solar panels for long periods of time.

About Keshee


Over the past few years, the overall trend has been to increase the energy density, and therefore capacity, of batteries without a corresponding increase in their physical size or cost. Historically the general trend has been for the available technology to advance at about 5-7% per year. Short-term gains over the next two to four years may come in optimizing how we charge lithium boat batteries, including more efficient and cost-effective forms of charging while underway. Solar power, for instance, continues to fall in price, while a greater range of companies now offers panels in custom sizes and shapes that can be tailored to neatly fit the available deck or coachroof space. Looking further ahead, the automotive industry is putting a huge effort into extending the total lifespan of batteries. To date, car manufacturers have generally guaranteed the batteries of their electric vehicles for 200,000km (125,000 miles), or eight years.
