Battery is dead but current is still flowing
The voltage of a battery is also known as the emf, the electromotive force. This emf can be thought of as the pressure that causes charges to flow through a circuit the battery is part of. This flow of charge is very similar to the flow of other things, such as heat or water. A flow of charge is known as a current.

How to Tell If a Deep Cycle Battery Is Bad
Shorts produce a lot of heat as the current is instantly released. Damage to a battery cell caused by a short. ... But you can also know when a battery is dead by checking its voltage. Typically, the voltage of a fully charged, 12-volt deep cycle battery is between 12.8V and 13V. ... if the battery still doesn''t hold a charge after attempting ...
How to Tell If a Car Battery Is Dead (and What to Do about It)
Jumpstart your car to recharge a dead battery. If it still won''t start or dies soon after starting, replace the battery or have a mechanic check the electrical system. To help your battery last longer, always turn off lights and electronics when you park. Get the battery maintained regularly and replace it if it''s more than 5 years old.
What happens when a battery is dead?
Most 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 pretty rare to completely drain a battery to zero, because it''ll have been more or less useless before …
Measuring a battery''s internal currents
A conventional voltmeter would tell you that when a battery is turned off, and disconnected from both the charging station and the electric motor, the overall current in the battery is zero. But in …
Does current flow inside a battery?
$begingroup$ @Sayn, there are chemical reactions going on between the electrodes and the dielectric to support this current. When the reagents for these reactions are exhausted, then the reaction can''t continue, the current stops, …

The SmartShunt appears to be dead. ... If there is a current reading while no current is flowing through the battery monitor, perform a zero current calibration while all loads are turned off or set the current threshold. 10.3.4. Incorrect state of charge reading.
Why is there a voltage drop across things when no current is flowing?
If you have an electric circuit with a 12V battery in series with an open switch and a resistor, the voltage drop across the open switch is 12V. ... The Ohm''s law states that the voltage drop developed across a conductor is proportional to the current flowing through the conductor, the proportionality being a property of the conductor itself ...

ELI5: Why Do Batteries Appear to Recover Some Charge When
When a battery is "dead", the greater portion of the reacting chemicals have reacted and it can no longer produce the "pressure" at a rate that is usable, but it''s still producing some.

Sometimes the problem could be with the charger rather than the battery or laptop. 8. Battery Replacement . Consider Battery Replacement: If none of the above steps resolve the issue, the battery itself might be failing. You may need to contact Lenovo support for a potential battery replacement, especially if your laptop is still under warranty.

These 20 minutes should be more than enough to jump the dead battery. At this stage, you will be able to connect this dead battery with the charger. The issue with the charger saying your battery is full will be fixed. So, yes! It is viable to jump a dead battery pretty easily. With that said, we would still recommend that you get help from an ...
Ohm''s Law confusion -
$begingroup$ In the circuit you have shown, yes current does flow through the 1GOhm resistor. As to the broader question, "does Ohm''s Law apply when the resistance is infinite?", personally I''d waft that away by saying Ohm''s law only applies to circuits - an (ideal) battery standing on its own does not constitute a circuit - but there are plenty more answers to …

With the engine running the alternator supplies current that both recharges the battery- or, once it''s recharged, maintains the charge - and runs the rest of the stuff on the car. If you have something like an enormous aftermarket stereo and/or a weak alternator there can be a current deficit during times of a high electrical load. This means ...
How is it that batteries can provide constant voltage until ...
A battery will also have a continuously decreasing flow rate, but it has a longer period of time where the flow rate is still fairly close to its peak. As far as when they die, a battery generally stops flowing charged at relatively high voltage compared to capacitors, as the affinity of the charges and electrodes of a battery is higher.
How can my battery be dead if electronic still work PSA.
You''re using "voltage" where you mean "current". If you need to simplify, use the good old water metaphor for voltage/current. The radio only requires a tiny trickle of water like a kitchen faucet, while the starter might require the same pressure (voltage) but it needs a firehose worth of flow (current) for a few seconds to start the engine.
