I guess my experience wasn't the same.
We were using SAFT, and a couple other vendors, of a three cell button pack
at something like 30mA IIRC.
Self-discharge wasn't large, and as long as you put a bit more in than
that, they stay up.
More than that, and you're making oxygen and hydrogen, and relying on
recombination to save you, and hydrogen is a slippery gas, gets out pretty
easy.  Those oxygen bowling balls aren't so hard to keep fenced in.
