I have a weekend package in my trailer with a 12 volt electric system (3 lights, 2 outlets, overhead fan). I use a solar panel to maintain the charge in the batteries. I originally had 2 12 volt deep cycle marine batteries, which must now be replaced. I do not operate any of the lights or fan for extended periods of time, maybe 3 to 5 minutes at a time, (I use battery lanterns mostly). The only constant draw is from a DVD player that operates about 1 hour a night. I would like to know if I could replace the marine batteries with acid batteries, since I do not wear down the batteries that much.

There are two types of marine batteries, starting and deep cycle, both can have lead acid wet cells.
The deep cycle batteries have stronger internal plates that allow the battery to be frequently depleted without warping or damaging the plates. A standard battery will usually have damage to the plates if they are constantly deep cycled. They will warp and short out internally.
You might be able to get away with a less expensive automotive battery, but if you were to leave a light on and completely drain it a few times, it might be damaged. Actually a high amp draw will heat up the cells more than a couple of small lights. A light draw usage might be possible with this type of battery.
Many new batteries come with a three year replacement warranty, and are pro rated for eighty or so months. Purchase those with a high CCA and see what happens.
