6 FAQs about [Will the battery be damaged if it is put into an external power supply ]
Can a power supply or charger damage a device?
In many cases, if the voltage is sufficiently different, then yes, the device could be damaged. If the voltage is correct, the amperage provided by your power supply or charger is almost guaranteed not to damage your device.
What happens if a power supply provides a higher voltage?
If the power supply provides a higher voltage than the device expects, it may damage the device. If the power supply provides the correct voltage, all is well. If the power supply provides a voltage lower than the device expects, it is unlikely to damage the device and also unlikely to work.
What happens if a battery voltage drops?
As the voltage drops, probably around 90% of the supply voltage, a setting is triggered that tells the power system external power is gone. In less than a few thousandths of a second, it tells a transistor somewhere to connect the battery, and life goes on.
What if my power supply is too high?
No exceptions. Your power supply provides electricity at a certain voltage. Common voltages are 5v, 12v, 24v, and others. The device you’re connecting to expects a certain voltage. These voltages should match. If the power supply provides a higher voltage than the device expects, it may damage the device.
Why does my laptop not use battery when plugged in?
The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery?
What if laptop lithium ion batteries continuously charged?
If laptop Lithium Ion batteries continually charged there would be a hell of a lot of laptops exploding. Seriously why comment when your information is super wrong. They are right except for the constant voltage part. Leaving a lithium battery at very high or very low state of charge for a long period is detrimental to its lifespan.
