The battery manufacturer recommends a charging voltage of 14.4-14.8V during the absorption stage and 13.6-13.8V during the float stage. The bubbling sound only starts in the absorption stage (14.4V per battery, 28.8V in my 2-battery system) and stops in the float stage (13.7V per battery, 27.2V in my 2-battery system).
You can see the lead plates at the bottom of the hole, and the slot for the fill tube at the top of the hole. Now, sealed batteries, such as gel or AGM, certainly have the ability to make noise when charging.
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
It was found by calculations and measurements that there is a cooling component in the lead-acid battery system which is caused by the endothermic discharge reactions and electrolysis of water during charging, related to entropy change contribution.
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
Never allow a sealed lead-acid battery to hiss or vent steam when charging! From my repeated research, a small amount of bubbling is acceptable with a sealed battery. They can recombine the evaporated water back into the electrolyte.
With a flooded lead-acid battery the sound will usually become barely audible as battery reads 13.8 on the voltmeter (minimum voltage for charging). As the volts on the voltmeter increase, the bubbling sound will increase in intensity. Normal charging ranges can go up to 14.8 with a flooded battery.

Yes, lead-acid batteries can generate noise during operation. This noise usually stems from internal reactions and physical movement within the battery. Lead-acid batteries work through chemical reactions that generate gas bubbles. When these bubbles form and collapse, they can create a gurgling or bubbling sound.

Lead acid release hydrogen gas while charging, should be fine, ensure the room is ventilated. Yes, it is more or less supposed to do that. That''s why you ''must'' check the liquid level occasionally. The ''bubbling'' agitates the liquid, a) properly mixing the acid with water, and b) ''replace'' the liquid in hard to get to corners of the lead plates.

The reason is that lead-acid batteries normally form bubbles on the plates during charging. And these get big enough and then rise. Some chargers will periodically reverse the charging voltage polarity for a moment in order to force the bubbles loose so as to keep them small, as the bubbles interfere with re-plating lead from solution back onto ...

Gassing Noise: Gassing noise occurs when lead acid batteries charge and emit hydrogen gas. This is a normal reaction when the battery reaches full charge, leading to electrolyte breakdown. The process, called electrolysis, causes the battery to heat and produce gas. It is essential to ensure proper ventilation during charging to prevent the accumulation of …
If the Battery bubbles, that usually means you produce Hydrogen and Oxygen (some call it HHO). That''s explosive. That usually means you lose water from the battery. If it is a vented lead-acid battery, then the bubbling noise you hear is an electrochemical reaction that occurs while charging a battery.

The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage …
