Which is best Charger for Marine Battery?

[volleybiggs]

I am getting ready for winter and wanted to make sure I charged my batteries during the winter off and on. I have a an old 12volt car battery charger that I was thinking of using to charge the batteries with. I have one that is the marine cranking battery and one that is a regular deep cycle marine battery. Thanks in advance.

As long as your auto charger does not take them over 14.4v you will be ok ....In the past I have used a 7 day timer and brought the charger ON for 1 hour every 7 days...saves the old brain.
