Can A Battery Have Voltage And No Amps? Troubleshooting Dead
Yes, a battery can have voltage but no amps. This occurs when the battery is in an unloaded state. Under load, voltage can drop and limit current delivery.
Charging
The charger throws amps in to the battery - as many as it can (while being limited by any specific limits set in the charger). As loads of amps pile in to the battery - the battery voltage rises. When the battery voltage
I am really struggling to understand what actually voltage is.
So we can see that voltage is a charge dépendant energy. If you have a positively charged particule stuck to a negatively charged particule, they would be at rest. Pull them apart, and you have invested energy into the system. They now have a potential energy between them and will spend energy to come back together. V = E/C Voltage equals

$begingroup$ The voltage decrease over time varies from battery to battery. In general though, the voltage will drop rapidly at first, then reach some steady state which it will hold for a long time. Once the battery''s
Why does current still flow with no voltage?
The point is that in the real world, all connection wires do have a (very small) resistance. V=IR is true for all connecting wires. So the current in the shorting wire is determined by the total of the internal resistance of the battery and the (much smaller) resistance of

6 FAQs about [What to do if the new energy battery has no voltage]
Can you fix a battery with no current?
No, you generally cannot fix a battery that has voltage but no current. This situation indicates that the battery likely has internal damage or a significant inability to deliver power. This issue often arises due to internal corrosion, sulfation, or electrolyte depletion.
How do I revive a battery that won't charge?
Reviving a battery that won’t charge involves a systematic approach, from checking the charging system to considering a battery replacement. By following the steps outlined in this guide, you can effectively troubleshoot and potentially restore your battery’s charging capabilities.
What happens if a battery has no load?
No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged. Open Circuit Voltage: Measuring voltage in a circuit with no load gives the open circuit voltage.
Can a battery have voltage but no current?
Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.
Why does a battery have no current?
No Current Flow: A battery may have voltage but not deliver current due to internal resistance or damage. High resistance can prevent current from flowing even if a voltage exists. No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged.
What should I do if my battery is overcharging?
Monitor the Charging Process: Charge the battery under supervision to avoid overcharging, which can cause overheating or damage to the battery. Return to the Standard Charger: Once the battery shows signs of life, switch back to the standard charger to complete the charging process.
