If you have a battery charged but no cranking power, another reason behind it could be a loose connection between the battery and the battery terminals. The terminals can also get corroded with time and result in a bad connection. To check if the battery has a good connection with the terminals, you can perform a quick load test with a multimeter.
When your lithium-ion battery fails to show any signs of charging—no LEDs light up, and no power seems to be reaching the device—it can be quite baffling. This scenario often points to a battery that might be in a deep discharge state where the voltage has fallen below a safe level, making it unresponsive to standard charging methods.
Another common reason behind a car battery having volts but no amps are bad contact somewhere between the rectifier and the load of the battery. You need to between the load and the anode bar to know if this is the case. If you see a drop in voltage when testing it, you can confirm that there’s a bad connection.
Key Takeaways Voltage vs. Current: Voltage can be present in a battery without significant current (amps). Battery Health Indicators: Voltage alone is not a reliable indicator of a battery’s ability to deliver power. Internal Resistance: High internal resistance can lead to a situation where a battery shows voltage but no current.
Batteries aren’t meant to last forever. Like all things, they also have a life span and they’ll go bad when the time comes. If your battery has voltage but no amps, it’s a sign that it’s reaching the end of its intended use. The battery dies due to sulfation of the plates inside or the acid or both.
The battery has enough voltage to power the lights (low current requirement) but not enough current to turn the starter motor. This discrepancy often indicates an underlying issue, like depleted battery cells or high internal resistance. Internal resistance is a key player in the battery’s performance.

Video - Battery Charging voltage & current in different stages (Bulk, Absorption, Float) How many amps do i need to charge a 12 volt battery. Amps are the total flow of electrons in the battery. So how many maximum and minimum amps per hour to charge your 12v battery to increase the battery life cycles. As a rule of thumb, the minimum amps required to charge a …
$begingroup$ A lithium battery cell is 4.2V when fully charged and is 3.2V or less when it is dead. Your cell is only 2.8V so it is dead. A dead cell cannot produce much current. It also might be ruined from being discharged to …
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 …

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.
The boost module has a USB output which I can then connect to my phone. My problem is that after connecting my phone, I can confirm a correct 5V but it only draws like 60-80mA (confirmed with my multimeter.) I …
Float only means no net charging current goes into battery. Full charging depends on fully completing transfer of lithium ions into graphite. If you are at or above 3.43v and charging current has dropped to near zero it is fully …
I will be willing to bet your battery is shot. . I will bet it''s over 5 years old. I will bet the water. In the battery is low. The easiest way to solve your problem with the least amount of aggravation is to Simply take the battery and have it tested and go from there. Now if the battery test good let us know and we''ll try and help you.
A lead-acid battery can have voltage but no current due to several reasons related to its internal condition or external connections. Here are some common causes. Sulfation: Explanation: Sulfation occurs when lead sulfate crystals build up on the battery plates, particularly if the battery has been left discharged for a long time.
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete. This method ensures the battery is not …
After 2/3 seconds, disconnect the battery right before the light comes on. Step 2: Repeat this mini-boost for 30 minutes. This will wake the battery from sleep and approach the normal charging threshold. Reason 6: Problem With The Battery. If your battery''s still not charging properly, your battery''s having charging health issues. This ...
After charging, repeat the previous test to verify if the battery now reads in the 12.6V range. Or else, consider having it thoroughly inspected before replacing it. Conclusion. Having no amp …
The main reasons behind a car battery has voltage but no amps are a dying battery, bad contact between rectifier and load, loose connection, malfunctioning battery cell, and high resistance. You''d have to replace the battery to solve this problem in most cases.
Battery Health: 100.0%. Voltage: 4,557 millivolts. Charge/Discharge Rate: 0 milliwatts. Chemistry: Lithium Ion. Low Battery Capacity (1): 2,787 mWh. Low Battery Capacity (2): 3,557 mWh. Number of charge/discharge cycles: 0. So, I assume the battery discharged so much that it cannot start charging for some reason.
1, 12 v lithium battery voltage high: after full recharge let stand, the battery voltage is definitely too high, other monomers to normal. The cause of the problem: (1) sampling error; (2) the LMU equilibrium function or failure; (3) batteries capacity is low, charging voltage rise quickly. Processing method:
Classic sign of an old battery at the end of its useful life, it can have proper voltage but not be able to provide enough current. As @tcmichnorth says do a load test . How can i fix this problem? Leave the new battery in it. Can you access the electrolyte? If so, you can measure its density with a hydrometer, a few $.
