Do I need a special kind of battery charger for a 12 V deep cycle marine battery? Or will my regular battery charger that I use for a car battery work?
AND are u able to hook 4 Batteries together to trickle charge at one time, Or is that not a good idea?
 
That's kind of a loaded question. If you get the correct charger than yes, but need to know what type of battery like Gel, AGM, or FLA, and also the specs of a the charger.

If you put a AGM in some chargers for a FLA battery, it will go into an equalize mode which could ruin an AGM battery.

Some automotive chargers if seeing a battery in a depleted state could try to force too much amperage in a battery to shock it back to health.

After I read the charger manual, and the spec sheet, then I can know.

In general, could be a bad idea to use any old car charger.
