When the weights reached the ends of their chains [or the floor], your gravity battery was discharged. You recharged it by pulling the chain through the device to bring the weight up near the top of the chain again.

Where is some energy left untapped that we could tap without draining the source? Outside my office, cars travel back & forth almost constantly. Couldn't the electricity that powers the streetlights be generated by the weight of the cars, or their motion through a magnetic field? Seems a shame to waste all that motive power. Every staircase absorbs energy -- can we tap and store that?
