These Combo calcium maintenance free marine batteries are a perfect choice for many boats.  They discharge at approximately 3% per month, meaning the boat can be left unattended for some period of time without charging. (A normal lead acid battery discharges at 1% per day)

The Calcium Combo battery construction allows for continuous starting and deepy cycling applications such as radios, fishfinders and lights,  leaving enough power to start the motor.  Simple to parallel or place in series for 24 volts. 

Solid robust construction for the marine environment.  Select the sealed or maintenance free setting on your battery charger.

Suggestion: For most ouboards 50hp and above the SMFDCM31 battery is the perfect choice.
