Don:
I was referencing my Honda Fit car. Which is different from my Honda 2000eu generator that I use on the boat. Both IMO are very reliable. The car "fits" my needs perfectly. In four years I've managed to only put 16,000 miles on it. No, It's not electric sorry if I gave that impression. Though my lifestyle and driving needs is perfectly suited for an electric car if one was available and was was not crazily overpriced. It's also one of the reasons why I did not buy a Prius as it was not suitable for my driving needs. My point was the three year old car battery has already needed to be replaced while my boat's 48 volt AGM bank shows no signs of failing after four years. Yes, the boat bank does not get jared as much as the car so that's part of it. It's also a deep cycle compared to the cars starting type. I also keep a closer eye on it and use solar and wind (though my wind generator was not installed this year) along with an occassional AC charge to keep things topped up and in balance. Not sure how well a Tesla car batteries hold up. But, I know of one Prius owner that needed her battery pack replaced under warrenty. Not sure why though. I think we are all still trying to see how long a battery bank (flooded, AGM, Lithium) will last in some of our electric boats. I can't speak for others but, so far so good on my boat for four years so far.

Hi Mike,
I value your veiw.
Your blog is an inspiration to us all on this forum.
I re visited your blog to look for a reference to a 97 Honda
but I have to assume it is a car not a generator that you are refering
to. Now is it an electric car battery pack? Or just the starting battery you mentioned. I wonder how long the Tesla battery packs have lasted.There should be some info by now. They have been around for awhile.
Boats would seem to jar the pack less, is that your drift?
If so , just another plus for applying elec to boats. Of course the other obvious is cruise/elec. boating usually means going someplace and then sitting there for awhile, perfect for charging via solar, wind, shore power, etc. Really does seem to be a better(easier)fit than cars.

I was just on the boat yesterday and fired up the Dual Pro charger and the batteries came up to charge with in thirty seconds or so of each other. I've probably only taken them down 30% at most on my trips so I'm hoping to get a lot of charge cycles out of them at that rate. I'm not sure but, I figure I might have charged them perhaps 50 times tops using the chargers over the past four years.  My 1997 Honda on the other hand has already had to have it's battery replaced last year. Though it is of course of a different plate construction and gets bounced around a bit more. Part of me thinks maybe I should use these batteries at home in the winter as part of my continuing solar conversion of my house. But, the idea of lugging 800 pounds of AGM batteries around with the real chance of dropping and damaging them prevents me from actually doing it.
