I have been removing and re-installing/alternating my Lifeline AGM batteries for 3 years now. But they are 31 size and are very heavy (70lbs!) and bulky to move. When I researched these, I thought I read on their website that one of the benefits of AGM (at least from Lifeline) is you can keep them on-board throughout the winter.

The website does not have that information anymore or I forgot where I read it. It does list CCA down to 0 and various specs down to -40 F.

Anyone know? I know ideally they should be removed for the winter, but with 3 of them, it would be easy to leave them in and I could visit and stay a little bit during the winter.

Also, a not-so-hands-on slip neighbor says he doesn't take his wet cell batteries off and hasn't since the boat was new 3 seasons ago.
