They usually lack the CCA (Cold Cranking Amps) especially in cold weather. There are also charge/discharge issues as cars need real quick bursts of power.Originally posted by Toploader View PostWhat I Own: 1993 Mercury Grand Marquis GS

A deep cycle battery can tolerate longer periods of discharge, but usually don't have a bunch of cranking amps. Great for running 12v equipment that doesn't need super high amp draw.
Marine starting batteries do exist, and are much like automotive batteries designed for an initial high amp draw starting cycle and then to be maintained with an alternator or by other charging means. Typically the only inclusion of a marine starting battery is threaded lug terminals and conventional post terminals.
