Not really. A lead-acid battery should be charged to something like
14.5 volts to get it fully charged (and it's important to get them
fully charged sometimes). Then, when it's fully charged, the charger
should drop back to 13.5 volts or so to maintain the battery in
'float'. Most 'intelligent' lead-acid battery chargers will do
something like this, the 14.5 volts guarantees full charge but if
maintained long term will make the battery gas. Really clever
chargers will occasionally wake up out of float mode and do a sort of
battery conditioning sequence.


Very odd. SLA batteries have been charged at constant voltage for many
many years. What has changed?
