If you switch the light on and then instantly start switching it back off again, there is a minimum amount of time that the light will be on and you can''t do anything to make that "on"

6 FAQs about [Battery charging whistling sound]
Why does my battery make a noise when charging?
That noise is called "coil whine" and comes from the windings of the transformer (s) inside the charger. An electrical engineer (which I am NOT) could probably explain why you get the noise with one battery and not the other; I can only speculate that the charger is having to crank up the voltage a bit to force a charge into that one.
Why does my smart charger make a hissing sound?
If your charging voltage is too high, you can also run the risk of the battery whistling or hissing. Most smart chargers take care of this problem, but if your smart charger enters into “desulfation” or “equalization” mode, then it will get up to 15 or 16 volts which can quickly lead to a hissing sound.
Can a lithium battery make a hissing noise?
Your lithium battery should never hiss, but if you hear a hissing noise from your lithium battery then it may be about to explode, catch fire and cause other catastrophic failures. If you notice the battery in your electronic device is making noise the best line of action is to remove the battery from the device.
Why does a battery make a hissing noise?
the only way thebattery will make hissing noise is when the current is more than the battery can absorb chemically.

Trying to use it will possibly cause fire or explosion. You can take your device to a safe place where there is nothing incombustible and take out the battery pack.
