Your alternator is working less hard with a full charge to start with, so there is some benefit, and the deep cycle is more suited to this kind of use than a regular automotive starting battery.

You are moving along the same path that I am, but I have a few larger fish to fry before I get back to alternator work. I have the kill switch already working, but the old starting battery I have won't die.
Thanks for the response, hey. My old starting battery held on a long time too. In fact, it probably would still serve, but I got tired of it's occasional semi-failure and of kinda fearing a sudden complete failure at some point when I might really need it to work.

I tried a full alt disable late today--took off both the white cable and the 4P connector, leaving the belt in place. A test run was satisfactory. Over about 15 miles the volt meter showed a decline from the 12.5 to 12.1/12.3. LED brake and running lights probably help a lot, as did the maintainer, I'm sure.

I am at a loss as to a really good plan for the alt disable switch and how to integrate the 20w/1.5amp solar panel that will complete this mod.

I have a trip planned for tomorrow that I can't avoid and that I plan to do alt free... we'll see if I make it!

My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
