Expectations vs. Reality: Making Sense of Battery Voltage & Percentages
Looking back at the State of Charge chart above, the battery only dips below 12V below 9% capacity. So, when it crashes, it crashes hard -- as Sarah and Mark discovered. But a Lead Acid battery dips below 12V at just under 50% capacity. So a 12V motor, like the fan, will simply slow down if it''s getting less than its "nominal voltage."

How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
Lead Acid Battery Voltage Charts – 6V, 12V, 24V, 48V
Lead acid batteries, like all other types of batteries, have a varied voltage at various stages of charge. A 12V sealed lead acid battery, for instance, has a 12.89V at 100% charge, and when it drops to 11.63V, it is said to be at 0% charge. The good news is that lead acid battery state of charge (SOC) charts are available if you need to …

12 Volt Battery Voltage Chart
For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less. ... The recommended charging voltage for a 12V lead-acid battery is between 13.8-14.5 volts. However, it is important to note that overcharging a battery can cause ...
Car Battery Voltage: Know the Basics of the 12V Car Battery
This is happens because each 2-volt cell isn''t exactly 2 V: they may be 2.1 V or more. But 12.6 V is what you expect from a fully charged battery. Car Battery Voltage When Off. According to the chart above, a properly charged car battery may have a voltage above 12 V, up to 12.7 volts. Car Battery Voltage After Resting
Why does the voltage of a lead-acid battery drop with load?
It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets quite depleted of stored energy.
Lead-acid battery
Float voltage varies depending on battery type (flooded cells, gelled electrolyte, absorbed glass mat), and ranges from 1.8 V to 2.27 V. Equalization voltage, and charging voltage for sulfated cells, can range …

Battery Myth | Why is My 12 Volt Battery Reading as 13 Volts?
All Lead acid batteries (Gel, AGM, Flooded, Drycell, etc) are made up of a series of 2.2 volt cells that are bridged together in series to reach their final desired voltage. For instance, a 6 volt battery will have 3 cells(3 x2.2= 6.6 volts), a 12 volt battery will have 6 cells(6 x2.2=13.2 volts) and so on.That 2.2 volts is the fully charged ...
