AAA batteries are rated at 1.5V as are AA-C-D batteries. Once down to 1.3V or lower they are not much use,

Can a 0.9V 400MA solar panel be used to charge 2 AA batteries?
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
What is true about voltage?
Difference in potential between two points. Like the voltage of an energizer AA battery is 1.5 volts BETWEEN its terminals. If you place two AA batteries in a flashlight, the voltage of the series combination of AA batteries from one tip to the other is now 3 volts.
What is low battery voltage?
It's what happens when a battery is about to expire.
How much voltage does a battery produce?
Depends on the battery but they are current sources as opposed to voltage sources Standard AA, AAA, C and D batteries all give 1.5 volts each, but rechargeable NiMH batteries are often 1.2 or 1.25 volts.
What is an example of a source of voltage?
A battery.
What is the voltage of AA battery's?
1.5volts DC
How much volts can a AA battery supply?
AA zinc and alkaline batteries normally provide 1.5 Volts when they are new. The voltage will drop as the battery discharges. Rechargeable batteries using NiCad or NiMH technology deliver 1.2 Volts when fully charged. Again, the voltage will drop as they discharge. It is this small voltage difference that can make rechargeable batteries less effective for some voltage sensitive applications,
How many volts are supplied by a AA battery?
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.

What is a voltage source that uses DC?
A car battery or an AA cell.
What is the highest voltage of a battery that you can buy?
The highest voltage battery money can buy is the 34 sub zinc ion battery it is 180 volts. (aa and aaa are 1.5)
Why is it safe to touch a AA battery?
Such batteries don't have a high voltage - only about 1.5 V.
What happens when you connect batteries of different capacities i.e Ah in parallel or in series in a circuit?
Capacity in Ah is not directly related to voltage. If you have 3 AA batteries, each with different mAh ratings, you should be able to connect them in parallel or series to your hearts content. In series, the voltage will be additive: 3*(1.5volts) = 4.5 volts total voltage across all three batteries in series, assuming the battery voltage is 1.5 volts. In parallel, the voltage will be equivalent to 1 battery. In parallel, the three batteries are able to provide 3 times more current at 1.5 volts than if all three are in series at 4.5 volts. Be careful when parallelling batteries of different voltages though. This is not a good idea, as they will try to force each other to match terminal voltage (voltage at the outputs of the batteries). An example: 1.5 volt AA battery, and a 12 volt car battery can be put in series - the total voltage will be 13.5 volts. The total current that can be sourced will be limitted by the AA's limit (much less than the car battery's limit). If put in parallel, the AA will try to force the voltage of the car battery down to 1.5 volts by drawing current into itself from the car battery. Alternately, the car battery will try to force the AA to 12 volts by pushing current into the AA battery. The AA battery will overheat, and likely catastrophically fail (blow up).
Will a double AA battery's voltage kill a human?
No. Voltage doesn't kill you, amperage does, and the amperage produced by a AA battery is not even enough to cause a tingle. Amperage AND voltage kills. Should also include frequency in that equation. 120 v/ 10 amps of 400 hertz kills faster than 60 hz. Amps with low voltage will do no harm. You need both to kill. One AA battery would not kill you but put together enough of them? Why not?
How many volts do 3 AA batteries supply?
A single AA battery will produce 1.5 volts. In series the voltage is additive. In parallel the voltage remains the same but the batteries total capacity is increased.
What is the definition of voltage?
Difference in potential between two points. Like the voltage of an energizer AA battery is 1.5 volts BETWEEN its terminals. If you place two AA batteries in a flashlight, the voltage of the series combination of AA batteries from one tip to the other is now 3 volts.
What voltage must the battery supply?
depends on the kind of battery. a regular battery (aa,aaa,d,c) should supply 1.5 volts. a car battery should supply 12 volts
