What is the best way to discharge a battery without using it?

I use this thing.

Made of JB Weld (Serious) (main structure of item made from epoxy)

battery discharger [20200616_183506] Inside it has four 10K resistors in parallel. It’s slow, but does the job. A small battery might take a week to get to storage charge, a large 100 cell battery may take many weeks. I made another one with about fifteen 10K resistors but it instantly melted itself apart. And this is how you use it, in practice. Don’t go too far! [20200616_183542]
