Overcharging a marine battery can lead to a number of problems, including reduced battery life, increased risk of fire, and damage to the battery itself.

Will a boat battery recharge itself?

Yes, marine batteries charge themselves. Most outboards with an electric start will re-charge the battery as they run.

How do you tell if a marine battery is fully charged?

When the battery charger senses that the battery is fully charged and will accept no further current, it reverts to float mode; the charging current is very slight, just enough to keep the battery in a fully charged condition. Flooded lead-acid batteries should have electrolyte levels topped up with distilled water.
