Sunset Marine is here to handle your boats starting and deep cycle battery needs. We are a proud distributor of INTERSTATE BATTERIES; the Marine industries most trusted battery.
Batteries on your boat handle two basic kinds of tasks, starting an engine and running electrical loads like lights, electronics and accessories for longer time periods. To choose a battery, first determine the battery's application and then choose from one of the four battery chemistries: flooded, gel, AGM or Lithium.
Deep cycle batteries
Compared to starting batteries, which deliver high bursts of energy for short periods, deep cycle batteries recover fully after being heavily discharged over longer periods because their design features thicker plates with a high content of antimony. Overnight, their use might deplete 50-70 percent of the battery capacity, depending on the house loads of the boat. When the batteries are recharged, energy is re-deposited into the bank, and the process, or cycle, starts over. Generally, deep cycle batteries should be sized to store three to four times the expected amount of energy to be used between recharge cycles.
