You will need to add more details.
The voltage will always be 12 volts from a 12 volt source until a circuit is completed, discounting any discharging of a battery.
12V out refers to the 12-volt output voltage of a power source or battery. "Ing" and "batt" likely stand for "input" and "battery," indicating that the output voltage is either going into a system for use (input) or being generated by a connected battery.
12V
NO, voltage of the charger must match the battery voltage.
12v
12V 5Ah
Voltage is the same but amp hour capacity of the car battery is much higher.
Yes. You will need a voltage regulator circuit to produce the 7.2v from the 12v source.
If the 12 volt solar panel output voltage is always higher than the 6.5 watt battery voltage. To charge a battery, a voltage greater than the battery must be applied to the battery, otherwise the battery will try to charge the charger.
Usually 6v, can be 12v.
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
It is not recommended to recharge a 3V battery with a 12V charger as this may damage the battery. The voltage of the charger should match the voltage of the battery to avoid overcharging and potential safety hazards. It is best to use a charger specifically designed for the 3V battery.
You can replace a battery with a battery of the same voltage but greater capacity as long as it will physically fit.
