Most battery tenders, solar panels are 250ma or in that range. The AC ones are about 1 to 1.5 amps. They basically maintain the battery, so it says fully charged. At 350 ma, it would take weeks if at all, at 1 to 1.5 a few days and at 6 amps, 24 to 36 hours to charge up. Of course you can go with a bigger one.
Bass Pro is not cheap. I would use a good 3 stage charger, as in ProMariner or Guest. From Hodges Marine, about $70.00 for a 6 amp one.

Here is what a good 3 stage charger will do. The important thing here too is desulfating, this will make your wet cells lasting longer.
Stage 1: Charging
During this mode, the ProSport will use its available charging amps (as controlled
by temperature) until battery voltage is raised to 14.6 VDC (Factory setting for
standard Flooded (Lead-acid) / AGM batteries).
Stage 2: Conditioning
The ProSport will hold batteries at 14.6 VDC (Factory setting for Flooded (Lead-acid) / AGM
batteries) providing a 100% charge to each battery, while conditioning batteries by desulfating
each battery. Upon completion, the ProSport will go to into its maintenance mode.
Stage 3: Maintenance Mode
During this mode, the Red Charging LED and the RED Battery Type LED (Factory set
charge profile for standard Flooded (Lead-acid / AGM Batteries) will turn off indicating
the Charge Process is completed, followed by the Green READY LED turning.
