maintain your batteries over winter

[Kent]

I have always left my batteries on my boats and all of my boats have been stored outdoors. I typically charge them once during the winter (on a day that is not bitterly cold). Because my trolling batteries are extremely difficult to get to (horrible engineering by the boat manufacturer) I only check the water level once a year and even then I rarely find that they need any water. My batteries have lasted over 3 years, so I see no reason to change what I am doing; especially, since I often use my boat up into January and then begin using it again in March or April at the latest.
