What Voltage is Considered Bad for a Car Battery?
Sometimes it just means the battery is discharged and needs to be fully-charged with a battery charger. The same is true when measuring battery voltage to determine if a battery has gone bad. Fully-charged, most car batteries will measure at least 12.6 volts (~13.0-13.2V for OPTIMA YELLOWTOPs), but low voltage doesn''t necessarily equal a …
Easy explanation: RV Battery Voltage and State of Charge
The battery voltage is what a voltmeter reads, or how many of those four lights are illuminated on your display. The state of charge (SOC) is what the actual storage status of your battery is, 100% being fully charged and 0% being flat dead.. The reason there''s not a simple relationship between battery voltage and state of charge is that …

4.2 Electromotive Force: Terminal Voltage
There are two voltage sources when a battery charger is used. Voltage sources connected in series are relatively simple. When voltage sources are in series, their internal resistances add and their emfs add algebraically (see Figure 4.17). Series connections of voltage sources are common—for example, in flashlights, toys, and other appliances.
