I just replaced my 3 yr old Wal-mart deep cycle battery with a Delco Voyager. I usually charge the battery after every fishing trip so it never really gets a deep drawdown. Am I shortening the life of the battery by doing this, or should I let it get a little lower before recharging. I used to use Voyager batteries and just feel 3 yrs with the Wal-mart batttery wasn't a long enough life-span.
