You don't say whether it's lead acid or lithium, but assuming it's lithium, there are several items on the web with guidance on storage procedures. I'm attaching one file I had saved plus here's a pointer to a thread on Endless Sphere on the topic.
Endless-sphere.com ? View topic - Storage voltage for LiFePo4 cell?
Bottom line - for long term storage of Lithium -- somewhere between 40-60% SOC and a cool place.
