After spending some time on a friend's cruising boat that had a Xantrex LinkPro battery monitor, I bought a LinkLite for Imzadi.
Several on EBay for around $200 - and I see the price has gone up a lot since I bought mine. http://www.ebay.com/itm/Xantrex-Linklite-Battery-Monitor-/311605137761?hash= item488d1d1161:g:jmgAAOSwhRxXKO5R&vxp=mtr The device monitors voltage for two banks, and shows instantaneous current in or out for the main bank, total AH used since the last charge for the main bank, and % or total AH remaining. It adjusts for the total AH available when you do a periodic "synchronize" after a full charge. It doesn't show you the total AH capacity for the main bank, but knowing the AH used and the & of total remaining you can do some arithmetic to calculate the total AH available. As a matter of fact, I happen to have done that when I was on the boat on Sunday. The house bank was at 93.2% of capacity, and based on the AH used I figured my house bank is down to a bit over 400AH from the 460 it was when the batteries were installed in 2010.

I have all LED lights, a 240 watt solar panel and modern refrigeration. The batteries are working fine but there is no way they are still performing as new. I would like to monitor their amp hour capacity as they age. Is there a simple way to do it or do I need to take them into a battery shop? 90 days to launch!
