I have searched the "FAQ'S" and read what I can find on battery care but I still have a basic question.....<br /><br />I took my battery (a "boat US" dual purpose starting and deep cycle) off the boat and put it in the basement for winter. Then I bought a 6 and 12 volt (1 amp charge rate) charger. I have been told of two ways to maintain / charge it and I don't know which is correct.<br /><br />method 1 - hook it up to the charger, leave it on all winter and add distilled water once per month.<br /><br />method 2 - every month or two hook it up to the charger for a couple of days, check the water level and top it off if needed (no reference to what type of water to use.<br /><br />What is the best way to do it?<br /><br />Thanks in advance for your input--<br /><br />Kramer
