Very Inexpensive Battery Maintenance Charger
1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but ...

Snowman,
Obviously they were never properly maintained, so they may have been "boiled dry" during regular boost charging. This seems a more likely scenario to me. And yes, long term floating could exacerbate an already bad situation.
We'll have to disagree. :)
These were chargers that have no boost. Either the old Magnetek single stage, or WFCO supposed 2 or 3 stage that never goes over 13.8v anyway.
In that case, yes, a prolonged 13.?v charge, left unattended for many months, could dry them out, especially at higher temps. But I'm more inclined to lay blame on the previous owners than the float charger. No FLA battery is completely maintenance free, and I'd rather float a little higher and replace a little water, than float lower and risk more settling. That said, I don't float mine, anyway. :)
