If I lived where it is hot, I would need a lower Float voltage.
The float voltage needed at any given temperature apparently varies by battery design and/or type.
My particular AGM batteries say right on their labels to use a float voltage of 13.5 volts to 13.8 volts, making my 7345 perfectly safe for them from a water vapor loss viewpoint while being floated.
Maybe all wet cell lead acid batteries should be floated at around 13.2 temperature compensated volts - I don't know. It looks like dry cell lead acid (AGM) batteries can be different. For instance, Lifeline recommends a nominal float voltage of 13.2 volts for their AGM batteries. (However, MEX floats his Lifeline AGM battery at somewhat over 13.5 volts, I believe.)
