A "hum" or "whine" is relatively normal, and likely an innocent by-product of the transformer using electromagnetic plates to convert current.

AI Customer ServiceA "fizz" sound is basically impulse noise, like static, but it can also sound a little mechanical because it gets carried by physical components. It isn''t a normal or benign sound.
AI Customer ServiceThere is a low, but noticeable buzzing noise coming out around the charger port when I leave the laptop charger on while the battery is full. It starts as soon as the battery is
AI Customer ServiceI recently bought an old motorcycle and charged the battery on my trusty automotive style battery charger after it lost charge. After several hours, the water was boiling inside the battery. I''m

AI Customer ServiceThe battery low alert is a sound that indicates that the battery life of the hearing aid is running low and needs to be replaced. This sound is usually a repeated beep that becomes more frequent
AI Customer ServiceTo keep it simple, if the battery sounds like a carbonated beverage when charging, then I''m not at all worried (assuming it''s hooked to a quality smart charger with a float mode). If you hear gurgling, or hissing from your gel or
AI Customer ServiceA hiss could possibly be the battery itself having a bad time, which is an immediate issue. A whine is more likely to be the electronics driving/managing the battery, which is less of an immediate
AI Customer ServiceThe answer is a phenomenon called magnetostriction. As electrical current passes through a transformer core, it becomes magnetised in a specific direction; so-called magnetic domains in
AI Customer ServiceThere are going to be some sort of sine with distortion and noise coming from your wall and while it's charging the chargers doing what it's supposed to do, but when your battery is fully charged, the filtering noise do occasionally get loud on certain chargers.
When the battery is being charged the circuit switches at a very high frequency, however the fine control needed to keep the current constant as well as certain combinations of voltage and load can cause the coil to resonate at a frequency in the audible range, thus producing a high-pitched sound.
Battery banks should be silent, save for a fan if it's a very large one. Any other noise means it's likely not functioning correctly, and has the potential to explode/go up in flames at any time, in use or not. Voltage converters and regulators can making a hissing sound which might change with what is plugged into it.
Hearing noise from your battery is dangerous as there can be a risk of fire or explosion. The simplest way to get rid of the noise in your lithium-ion battery is to replace your old battery with a brand-new set. You can also contact your device company’s technical support for assistance, particularly if it’s within the warranty period.
A loud battery backup noise should concern you. Even though battery backups are not necessarily silent, the sounds they generate are not loud enough to disrupt your work. That doesn’t include ordinary alarms such as those designed to tell you that the battery is depleted.
Since the noise sounds like a chirp, there's varying frequency involved. Probably a converter that ramps up or down in frequency as it starts up or shuts down, or triggers some feature like current or voltage limiting. Maybe it does that when it decides the battery is charged and it should stop charging.
