All factors that have a well understood detrimental impact on the service life of lead acid batteries [27]. In addition, for a fully charged lead–acid battery, high-frequency ripple can be destructive through overcharge, especially due the large differences in electrochemical efficiency for charge and discharge [21].
You are correct, the lead acid batteries are best charged on a CC-CV methods. However, constant current doesn''t mean that the battery has to be fed an exact pre-determined current or the battery suffers. It would be better interpreted as a maximum current that the battery can be charged at.
