Sorry that I missed this post and left you hanging. I concluded that i needed the higher amp charger for the sake of the battery longevity and function. My battery is rated about 40 amp hours and I got their 25 amp charger. As you learned, the theory is that you get throuh the bulk charging phase fast enough that there is lots of time fo the float charge. More time apparently means better battery condition long term. I have had this set up for maybe two years now without any problems. I drive a 11-14 mile comute each day, charging only at home, sometimes using the alt to extend range. Sometimes i charge at work (free) too. I never let the battery too-deeply discharge.

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.
