never tried it out with bleach so im not too sure
but if connect enough cells in series you can get 9V :L (which would be quite tedious)
i know for the HCL/magnesium/copper you can get 11-12V with 4 cells
you can make a multi-celled battery that can easily go over 9V using HCL (can get at hardware stores) ,magnesium and copper
not sure if they would classify as household objects though
