The noise could be a relay that is getting pulled in, then dropping out again – which would cause the clicking sound. Most cars have a load reduction relay, and there may be others as well, that apply power only when the ignition is on. Usually the clicking sound happens when the battery is very low, so it is a bit puzzling that you''re hearing this when the battery seems to get good.

6 FAQs about [The knocking sound of the lithium battery shell becomes louder]
Do lithium batteries make noise?
However, lithium batteries are not supposed to make noise. So if you begin to hear strange noises from your lithium battery then there is an underlying problem that needs to be addressed quickly. Hearing noise from your battery is dangerous as there can be a risk of fire or explosion.
Why is my lithium ion making weird noises?
If your lithium-ion is making weird noises the best line of action is to replace the battery with a brand-new set. If the noise stops then the battery is the cause of the noise but if the hissing noise persists then it may be coming from your electronic device.
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 is my battery making a loud noise?
You can place it on concrete and perhaps call your local fire department. Voltage noise occurs when your battery suffers a short circuit. The increased voltage noise usually occurs when the metallic lithium anode and the heterogeneous discharge thereof.
Does a lithium-ion battery fail in high-speed collisions?
Lithium-ion battery failures, particularly in the case of high-speed collisions in electric vehicles, have become a growing concern. This study investigates the failure mechanism of an 18650 cylindrical battery which is indicated by the occurrence of an inner short circuit at various loading rate.
