Only leave the stuff you can afford to buy again. Would not leave much in outside storage or the battery. Mine was taken in a secure storage facility. If you see a bunch of end of its life lawn equipment or other small business type construction stuff, you might as well hang a Free sign on your battery. You will need to replace the connections if you are lucky enough that they were cut - not yanked out. Good luck.
