Slightly off topic because it's at any particular fixed temperature - when using the "wrong (too high of a)" float voltage for that temperature. A Lifeline representative told me over the phone that the lifetime of their batteries would be shortened because their batteries would be dryed out prematurely if I used a float voltage over their spec over the long term. That made perfect sense to me.
The same thing goes for any AGM battery at any temperature if one uses a float voltage that's too high for that temperature - it's lifetime will be shortened due to water vapor loss ... the same thing happens to wet cell lead acid batteries on a stock converter ... their water evaporates away.
I assume that the same temperature dependence issue is also why, with a multi-stage charger, all stages should be compensated (adjusted) for the air temperature around the battery ... so as to get max battery life.
