A new set of batteries should be arriving today to replace the original eight year old 8A4D batteries on board BIANKA. Due to the failure of one of the batteries I thought it best to replace the whole lot. While the remaining batteries seemed to be in good enough shape they would only degrade the new battery.  This would require me to do another whole swap in a few years anyway. I looked into Lithium Ion replacements and the economics just did not quite make sense yet because of the increased price and other add on items I would have to buy like a new charger. I found a 48 volt 200 amp hour Lithium Ion battery for around $5000. For the same amount of money I could replace all my AGM's two times and still have a sizable chunk of cash for other boat needs. The AGM's should last me a minimum of sixteen years based on my experience with the first bank. If Lithium prices come down as they have been predicting I will revisit the issue but, for now I'm going with what has worked for me the past eight years.
