I am using the output of a charger in the car intended to charge a battery  
used to power brakes on trailer.

This is my next step after replacing the battery. It may be that the charger  
in the car is not optimized for the marine deep cycle battery I am using.  
Research for another project suggests that it is better to have a smart  
charger that allows some amount of discharge before the bringing the battery  
back up to full charge rather than relying on charging whenever the car is

Yes, very important. This should be the first advice for any installation in  
cars. Also important to be sure ground leads are fused close to the aux
