Not cost. But there were two reasons. First, a desire to fit the battery and its charger into the former battery's space in the car rather than relocating. Second, it is part of a general program of shaving weight in small measures across multiple places. That weight program has shaved nearly 250 lbs for a car that started at 2262lbs and that is driven heavily through pulse and glide techniques. This battery mod removed 12 pounds, without losing enough CCA to start the engine. It is a motorcycle battery, but my 1.59cc four cyl Civic is not all that much more than a motorcycle in some ways. That's especially true because I reduced electrical loads so much: CD player replaced with a battery-operated mp3 player, LED bulbs, HID headlamps. Night driving kills the battery still. And I have a little more I can do to reduce electrical load.

If I had two like batteries in-line, would the ability of my Odyssey 6 amp charger to fully recharge both batteries be reduced?

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. 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.
