"Do Gravity Batteries Scale to Household Size?"
  
https://www.asme.org/topics-resources/content/do-gravity-batteries-scale-to-household-size

"Even with a 2,078-kilogram weight, they ultimately found that the cost 
of the materials used to build the prototype did not make sense for how 
little energy the battery was able to store."

"“We found that the energy storage capacity diminishes significantly 
with decreasing size,” Jarausch said. “The weight of the moving mass, a 
crucial factor, scales cubically, making it impractical for individual 
homes. This technology is more suitable for larger-scale applications 
like powering a city block or a small community.""

Gravity batteries are just another form of spring batteries.  Both 
technologies are difficult to work with and have corrosion problems.
