Coolidor Question

I have 1 1/2 lbs of beads in my ~100qt coolidor, I just have all my singles in old boxes and what ever boxes I buy get tossed in. No lining and i've been pretty bad the last year or so I've just never got around to replacing the battery in my hygro, but before that it died it was rock solid at 65% for 3 years and I need to add water to the beads every 3-4 months everything still smokes great so i'm willing to bet its still at 65%
