Shifting from 12V to 36V increases energy efficiency while keeping the required wiring at acceptable thickness. However you say that the fan uses two 12v batteries in series, which if it is in series it is a 24v fan not 12v. There is a chart of AGM battery voltages (when the battery is under load) here. The number of minutes a battery can deliver when discharged at a constant rate at 80°F (27°C) and maintain a voltage above 1.75 V/cell. Re: High/Low Voltage 12 Volt Lots of variables, what type battery, flooded, agm, gel, what temp is the battery at, etc, etc. There is a very big difference when a car battery drops even a small amount of voltage. They generally have a voltage level rating (typically 6v or 12V) as well as an Amp-hour rating, denoted as âAhâ. If a fully charged 12-volt AGM battery is connected to a load, its voltage may be anywhere between 11.75V and 12.9V depending on how much current is being drawn from the battery. Believe it or not, but a 12 volt battery should not be read with 12 volt to see if itâs fully charged or not. Battery to Troubleshoot Deep Cycle Battery Issues A properly maintained battery will last many years. ... Voltage. Comparison of Battery State-of-Chart to Open Circuit Voltage for 12-Volt Batteries Battery Types Explained At this voltage, the battery should regulate its own level of current. Step 3.
