Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.

[1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]
Carries about 250 kg of rocks or humans? This will equal the other example "A 100 kg human would have to climb stairs of ten floors (25 m) to match the little battery cell" of a mere 7 Wh. "The main problem with gravitational storage is that it is incredibly weak compared to" proper storage, as dothemath.ucsd.edu says
