I had some of the super cheap 100ah batteries sound like they were boiling when I plugged in the charger. The ink right on them said whatever voltage to apply to (if floating, there's another voltage for cycles) so I have to assume it's right.
I don't believe they've even left float voltage in the last year, so all I can say is that they're still sitting there.
