It should be still in the voltage-range. My thought is: the the amp "stops working" at about 14.5V. One cell has a discharge-voltage of 2.5V, it "stops working" at 2.5V, 5 batteries would "stop working" at 12.5V, 2.5 volts are still "left". So if I
High voltage when charging NiMH battery?
In this 4 pack NiMH battery, discharging starts at 4x1.2V = 4.8V but should be interrupted when voltage reaches 3x1.2V = 3.6V, or in the worst case, 3x1.0V = 3.0V. In the following chart shows typical cell voltage vs.

The charger puts out about 14.8V to charge a 12V battery during the day at peak (around 1pm). At night time, the battery is at about 12.8-13.1V fully charged. I disconnected the solar panel last week and the voltage has been steadily
Charging a 12V Battery with a 15V Charger: Safety,
No, you should not charge a 12V battery with a 15V charger. This higher voltage can lead to battery damage, overheating, reduced runtime, and a shorter. Most charge voltages range from 4.2 volts per cell, equating to 16.8 volts for a 4-cell pack. Voltage Tolerance: – Lead-acid batteries: They are more tolerant of over-voltage. For example
What Voltage Does a 20v Max Battery Cut Out : r/Dewalt
Just charge the pack at like 100mah untill the voltage comes up to like 15v so the charger can recognize the battery. Once the charger starts charging it should take care of balancing the cells. 11v is good that means all the cells are holding a little bit of a charge and none are shorted or completely depleted to 0v.
BU-405: Charging with a Power Supply

Today I let my car battery charger charge a car battery over about 8 hours and probed the voltage to be about 15V with still 2 amps being pumped through by the charger (though the current was slowly falling over time) Is the battery damaged? The charger is a standard one designated for car batteries not an improvised one.
Can You Charge A Car Battery At 15V? Voltage Concerns And
Charging a car battery at 15V can pose several risks, primarily because this voltage exceeds the standard charging voltage for most automotive batteries, which is typically around 12.6V to
Alternator charging at 15v
The charging voltage is adjusted depending on various parameters, such as the current level of engine efficiency. The smallest possible set value for the generator voltage is 12.2 volts, while the maximum charging voltage can be anywhere between 14.5 and 14.9 volts.
NiMh Batteries in Series (12v) Charger Question
The safest, simplest charger for NiCad or NiMh batteries is a constant-current charger (no specific voltage limit), where the charging current is controlled at 320mA (the 0.1C rate for a C=3200mAh battery). You use time to cut-off the charger after 14hours (you have to put 140% of C back in to fully-charge them, 14h*0.1C = 1.4C if they were fully discharged to begin
Maximum Voltage when charging 12V NiCd Battery pack (from cordless
The voltage changes with the amount of charge. If the battery has been charging for a long time then the rectifiers reduce the 15V to 13.2V and the battery is only 12.5V so the resistor has 13.2V - 12.5V= 0.7V and the current in the 8.2 ohm resistor is 0.7V/8.2 ohms= 85mA.

6 FAQs about [Battery pack charging voltage 15v]
How many volts does a 12V battery charge?
The charger puts out about 14.8V to charge a 12V battery during the day at peak (around 1pm). At night time, the battery is at about 12.8-13.1V fully charged. I disconnected the solar panel last week and the voltage has been steadily declining to 12.4V so far (I'm trying to see how long a full battery charge will last for this system).
Is a 15 volt battery a good voltage?
However, when the battery is in a refresh phase, the voltage may occasionally reach up to 15.2 volts. Ok, so it sounds like it is an acceptable voltage. I guess my only concern is that Ive never tested it below 15 volts and it's a brand new battery. I'll see how it goes over the next few days.
Is a 15V battery too high?
So basically, 15V shouldn't be too high, though its probably at the upper limit. Besides, a nominal 12V battery is really closer to 13V. Yes, that is too high. It will kill sealed batteries and cause a lot of gassing from flooded batteries. The absorption voltage should be about 14.4V and the float voltage should be about 13.8V.
Is 15 volts a high volt?
I think that 15 volts is on the high side even if it is within specs. The smart regenerative charge system primary strategy is stored in the BCM . The BCM receives all of the important information relating to the battery condition from the battery monitoring sensor via the LIN .
Why does my Charger pump out 16V?
This may depend on the type of battery & charger: Modern cars may use AGM batteries & smart alternators which can pump out >16v on occasion, likewise smart chargers may do this for specific reasons. Also, how are you measuring the voltage because cheap meters are not to be relied upon. Are you probing the voltage with the charger still attached?
How many volts is too high for a one-time charge?
Both will usually hold up to 15v charging just fine. Approaching 16v is a little too high for continuous charging. If it's already an old, weak or hot battery then I would definitely put it into "little" mode... otherwise send it.. So in your case at 15.75 isn't the end of the world for a one time charge.
