maintain your batteries over winter

[Bduck]

I am on with what dubob is saying about AGM batteries. My boat has shelter in the garage 24/7 when not in use, therefore no need to remove the batteries. I keep the onboard charger plugged in and periodically keep check. I bought an AGM marine 11yrs ago and its still going strong but all good things must end eventually. I also use one lead acid marine battery which has been changed out 3 times. AGMS are a little more costly but I have decided to make the switch over fully once my lead acid dies. When adding up the 3X the cost of lead acid I could have purchased 1 AGM with left over change. Although dubob knows what works for him which my way hasn't failed me either. I also feel keeping batteries out of the direct cold will aid in their longevity.
