How to change the parameter value of multiple (same) modules in Simulink?

I have more than a hundred of same battery modules on a project. Now I want to change the spec of all the battery.

Is there an easy way to do this other than to delete and redo everything again.

Usually, write a script to do it in a batch, using the following functions.

find_system()
get_param()
set_param()

Can you give me a specific example (or a link to a tutorial) to do this? I'm quite new to Simulink.

f14;
GainBlocks=find_system('f14','BlockType','Gain');
for k=1:numel(GainBlocks)
set_param(GainBlocks{k},'BackgroundColor','red');
end
