Re: [Amel Yacht Owners] Re: Batteries - What type house batteries to use & what voltage charge from Solar/Wind?
Bill & Judy Rouse <yahoogroups@...>
Is the charger switched to match the charging characteristics of your batteries? Didn't you switch the type of batteries and the charger? Has a qualified person checked the charging characteristics...and, did he determine that the charger is actually outputting the correct charging characteristics?
Did you get sealed batteries? If not, have you checked the fluid levels? I just replaced my batteries with 12 Trojan SCS200 batteries (115AH) in January in Martinique. Unlike my previous sealed batteries, I am able to/need to open the vents and add distilled water. I found that even when new, water needed to be added to several of the cells. In the last 5 months, I have checked the fluid levels twice and have added a total of about 2 gallons of distilled water! The Caribbean is one hot place!! I also have an indoor/outdoor thermometer installed in the battery compartment to monitor the temperature when the batteries are charging (thanks for the suggestion Bill Rouse). The battery compartment usually stays a couple of degrees above ambient.
I will check them one more time before putting Brava up on the hard for hurricane season, leaving the solar power on to keep them topped up i n voltage but with only the freshwater pump and the bilge pump left in the on position. The former will rinse the Dessalator membranes once a week for three minutes with fresh water from the tank.
It seems early in the life of your batteries to have to desulfate them, but maybe that would be worth a try.
