FWIW I use the little PC680 in my car, although I do have an alternator, and in between usage I simply turn-off the cutoff switch and it holds a charge just fine for weeks/months. I wonder if you could use one of these, charge it prior to storage and then disconnect it. If needed, charge again prior to use.
