The reason is that lead-acid batteries normally form bubbles on the plates during charging. And these get big enough and then rise.

6 Frequently Asked Questions about “Lead-acid batteries make a sharp screaming sound”

How do I know if a lead acid battery is flooded?

The red line is the edge of the slotted fill tube for a Flooded Lead Acid Battery. The blue is the water curve beneath it. The green is the 1/8″ space between. 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.

Why does my battery make a hissing noise when charging?

Now, sealed batteries, such as gel or AGM, certainly have the ability to make noise when charging. However, a hissing sound (or anything indicating that pressure is squeezing out – like steam) is an indication that too much charge is being applied and irreversible damage is occurring.

What does a flooded battery sound like?

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.

How does a flooded lead acid battery work?

This results in electrolysis which excites the electrolyte solution and releases hydrogen and oxygen gas from the “water” (evaporation). The red line is the edge of the slotted fill tube for a Flooded Lead Acid Battery. The blue is the water curve beneath it. The green is the 1/8″ space between.

What happens if a battery bubbles?

When a battery bubbles it is overcharging due to excessive amperage, voltage, or both. The excess electricity is breaking down the electrolyte in each of the cells and causing the battery to off-gas and bubble. If left unchecked, this can damage or destroy your battery. Tolerant of Bubbling? (Electrolysis)

Why is my battery Bubbling?

In the normal charging range, this bubbling is caused when an electric current from your charger is passing between the positive and negative plates in the battery's cells and through the electrolyte solution. This results in electrolysis which excites the electrolyte solution and releases hydrogen and oxygen gas from the “water” (evaporation).
