6 FAQs about [Lead-acid battery internal pressure is too high]

Can lead-acid batteries produce hydrogen & oxygen gasses?

ALL lead-acid batteries can produce hydrogen and oxygen gasses! Never charge lead-acid batteries in a sealed area or container to avoid the risk of hydrogen and oxygen gas buildup. Always charge lead-acid batteries with adequate ventilation and avoid making or breaking connections at the battery to prevent electrical discharges (sparks, arcs, or shorts).

What happens when a lead-acid battery is fully charged?

When a lead-acid battery is completely charged, continued charging causes the electrolyte to break down and form hydrogen and oxygen gases. This is the 'boiling' that we see when charging an automotive battery at a high rate near the end of a timed recharge.

Can a lead-acid battery be replaced?

In a sealed or maintenance-free lead-acid battery, the electrolyte cannot be replaced when it is lost. This results in a decrease in capacity and service life for all lead-acid batteries. A word of caution: ALL lead-acid batteries produce hydrogen and oxygen gasses during charging. Never charge lead-acid batteries in a sealed area or container.

What temperature should a lead-acid battery be charged?

Lead-acid batteries should be charged between 50 and 70 degrees Fahrenheit (10-21 degrees Celsius). The lead-acid chemistry gains capacity above 75 degrees and loses capacity below 60 degrees. Our first concern with a rechargeable battery is charging it.

What happens if a battery is sealed?

Two bad things are happening at this point: (1) An explosive gas mixture is forming in the sealed lead-acid battery and heat and pressure are building. If the pressure becomes great enough, the sealed one way valves on the battery will open and vent the excess gas pressure and possibly liquid electrolyte.

How do I charge a lead-acid battery?

To charge a lead-acid battery, first connect the charger to the battery system before powering up or plugging in the charger. Another caution for discharged batteries: The electrolyte at this point is mostly water and will freeze at a higher temperature (15 to 20 degrees F.) than a fully charged battery.
