Anything from 13.4 - 13.7 finishing voltage is fine for a flooded battery up to around 100F. After that figure is broached reduce finishing voltage by .3 Oooooo lookie just the exact mount that a 5-amp Schottky diode provides.
:? But don't I need to get to 14.8? There's clearly something significant here that I'm still not understanding.
In the case of what I'm doing currently, the resting battery voltage was 12.3V. After connecting the fully charged jumpstarter to the Interstate and plugging in the wart, the voltage at the battery terminals rapidly rose to about 12.6 and stabilized. Over the course of the next 24 hours the charging voltage has gradually risen to 13.3V. I'm expecting that over the next several days it will continue to rise to the high 14 range as the battery approaches 100% soc. So where does the 13.4 to 13.7 finishing voltage come in?
