What is a marine battery?
Marine batteries are considered a "hybrid" battery which actually falls between the starting and deep-cycle batteries. Marine batteries are usually rated using "MCA" or Marine cranking amp which is rated 32 degrees F, while CCA is at zero degree F. (For more information on CCA, CA & MCA, please see below)
What is the CCA rating?
The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V.

Note that the MCA is sometimes referred to as the cranking amperes or CA.
Where do I recycle my old batteries?
Old batteries may be returned to the battery retailer, automotive service station, a battery manufacturer or other authorized collection centres for recycling.
