Question on over-charging battery

[D.A.D.]

I hope an informed "teardropper" sees and replies to this question fairly quickly.
I have a new red-top Optima battery in my galley. I was told not to worry about gases or other safety issues by the salesperson in the industrial shop, as this battery is gel-type and sealed.
Having read this thread, I am now getting a little concerned with my set-up.
I had a truck and trailer shop install a battery isolator into the car's electrical system and then run 10 ga. positive and negative lines to my trailer via the 7-pole connectors, and then on back to the trailer battery. I have a circuit breaker mounted next to the TV battery and a 30Amp fuse wired into the hot-line right at the trailer battery.
My question was whether I can damage my trailer battery by over-charging it while in tow? Also the galley area only breathes through the roof vent and then only if it is open.
We want to leave first thing Saturday morning, so replies would really be appreciated. Thanks.

If the charging system in your tow vehicle is operating correctly you will not overcharge the Optima. The output from the alternator is regulated to about 14.5 Volts DC with the engine running at cuising speed. This is a good value to maintain a full charge in automotive 12V batteries (including the Optimas). The amperage output of the alternator goes up and down as the eletrical load changes inside the vehicle but the voltage stays the same.
