A dead battery can be pretty aggravating, but with a few battery tricks, you can revive a dead battery and continue driving. Here are some dead battery tricks that can get you
AI Customer ServiceFirstly, batteries are certainly not constant voltage sources. You could call them time-dependant constant voltage sources, at best. As a battery discharges, the voltage will start to drop. If you

AI Customer ServiceOnce a battery reaches a specific voltage, the chemical reaction can''t work against it as well and it just kind of hovers there (but it''s still reacting, which is why new batteries can go bad). When
AI Customer ServiceA battery''s charge and discharge cycle significantly affects its lifespan. When a battery loses charge and falls below a certain voltage, it can be challenging to recharge it. The
AI Customer ServiceWhen the battery is allowed to run almost completely dead, and then is recharged
AI Customer ServiceThat is because there is no current thru that resistance, hence no voltage drop across it. Any decent voltmeter will have at least 10 MΩ input resistance, which is so way

AI Customer ServiceWhen the material in the cathode or anode is consumed or no longer able to be used in the reaction, the battery is unable to produce electricity. At that point, your battery is "dead."
AI Customer ServiceThat is because there is no current thru that resistance, hence no voltage drop across it. Any decent voltmeter will have at least 10 MΩ input resistance, which is so way more than even a dead battery as to not matter.
AI Customer ServiceTry to start the engine of the car that contains the dead battery. Maynes explains that if the jumper cables and the battery you are charging have enough power, the car engine should turn over easily and start. If the engine
AI Customer ServiceNo ignition: If your battery is completely dead, you will not be able to get the motorcycle started at all. A bad or flat battery is usually the first suspected culprit in this
AI Customer ServiceIn fact, all batteries have a negative V-I curve; if you increase the current taken from them, their voltage decreases. This effect is like having a resistor in series with the battery. It is called the
AI Customer ServiceMaybe battery was the reason my Alienware M17x R4 crashing due to video TDR failure. My old battery was almost dead, holding charge up to 7% and windows says still charging but the
AI Customer ServiceAA Battery Current . We all know that AA batteries are a common size for many devices we use daily. But have you ever wondered how much current an AA battery can
AI Customer ServiceA dead 12-volt battery has a voltage range of 12.0 volts or lower. When the voltage drops below 10.5 volts, the battery is considered dead and needs to be replaced.
AI Customer ServiceIn fact, all batteries have a negative V-I curve; if you increase the current taken from them, their voltage decreases. This effect is like having a resistor in series with the battery. It is called the "internal resistance" or impedance sometimes.
AI Customer ServiceAlmost every Li-ion battery has copper as anode current collector. When copper is exposed to high anode voltage due to high discharge, the copper dissolute in to the
AI Customer ServiceUsing this equation, we can calculate the current, voltage, or resistance in a given circuit. For example, if we had a 1.5V battery that was connected in a closed circuit to a lightbulb with a
AI Customer ServiceMost commonly when we loosely say a battery is dead, it means the potential across the battery is too low to drive current/electrons hard enough to do what we want. It''s
AI Customer ServiceCorrosion around the battery terminals can be a sign of a problem. It often appears as a white, ashy substance on the battery posts. While this doesn''t always mean the
AI Customer ServiceAt 12.4 volts, the battery is about 75% charged, while at 12.1 volts, it is approximately 50% charged. Although the battery can still function, it should be recharged
AI Customer ServiceThe first thing you need to do is inspect the physical appearance of your battery for signs of damage. Always wear gloves when doing this. If you notice any cracks or leaking battery acid, do not attempt to
AI Customer ServiceThe only way a battery drains is if energy is being lost. In the case of a leakage path, energy is being lost through the current draw caused by the leakage. In batteries that don''t have current
AI Customer ServiceHere''s what I have tried with AA and AAA NiMH cells: set a bench power supply to a max. current of 1 A and 0 V. Connect the battery. Increase the voltage until the current
AI Customer ServiceYou can model the way a battery dies by increasing the internal resistance. A nearly dead battery still provides 1.5 volts, but has a very high internal resistance so that
AI Customer ServiceThe same rising current always flows in the battery and wire, but initially most of the energy shifted is still in the battery, because the current in the wire is still low. However, as the rate of
AI Customer ServiceOther thing the guy talking about fundamental things forgets is that real battery can be represented by rather complex circuit of ideal elements, like voltage source, current source, resistor, inductor and capacitor. Therefore, dead battery can show you almost any voltage between -4 to 4V after a misuse and at a certain conditions.
After 15 minutes, either you did something that increased the battery current enough to again trigger the dead-battery circuit, or possibly the small current drain caused the battery to become even more dead than it already was. Sometimes dead batteries will return to life if the are shaken.
Both effects occur as a battery is drained. The open circuit voltage goes down and the internal resistance goes up. Note that open circuit voltage is specifically measuring just the voltage the battery puts out with the internal resistance taken out of the equation.
You can model the way a battery dies by increasing the internal resistance. A nearly dead battery still provides 1.5 volts, but has a very high internal resistance so that drawing even a trickle of current zeros out the voltage gain.
In addition, as a battery runs out of juice, its internal resistance increases [also see] and so the slope of its IV curve increases. As you use a camera, the current requirement goes up and down. As the batteries run out of power, eventually the maximum current usage will give a voltage that is too low for your battery's voltage detection circuit.
In a standard use, you cannot drop the voltage below 2 volts, even if you wired the terminals together. Batteries will vary between 3.8 and 2.4 volts per cell. As voltage drops, internal resistance rises. The higher the internal resistance, the lower the current over the short circuit.
