Even if water is added, the plates should not be covered in water. That white foam stuff holds the water/sulfuric acid and is just "damp".

6 Frequently Asked Questions about “Lead-acid battery rubber cap is not covered”

How do you maintain a sealed lead acid battery?

It turns out that Sealed Lead Acid (SLA) batteries are not infact all that well sealed. You can perform maintenance on them much the same as you would any other wet cell battery, such as car batteries. In this instructable I will show you how to do this. What you will need: -Distilled water -Small straight screwdriver -superglue or hot glue

How do sealed lead acid batteries work?

By design sealed lead acid batteries are, by their very nature, sealed. This means that if they have been damaged by ovecharging and have dried out then it is problematic to restore them. Ironically it is possible to do this damage in the first place because they aren't completelysealed. There is a rubber cap on top of each cell.

Does a lead acid battery revert to lead and sulphuric acid?

In the highly charged state, a lead acid battery will revert to lead and sulphuric acid, only becoming lead sulphate when discharged. It's quite difficult to photograph the inside of the cells but the photo below is good enough to see that there is no liquid above the plates.

Are SLA batteries sealed?

It turns out that Sealed Lead Acid (SLA) batteries are not infact all that well sealed. You can perform maintenance on them much the same as you would any other wet cell battery, such as car batteries. In…

What happens if you charge a lead-acid battery too fast?

If a lead-acid battery is charged too much then the water contained within them can electrolyse to hydrogen and oxygen. This process is called gassing. If the charging isn't too rapid then the hydrogen and oxygen recombine within the cell and re-form to water: no harm done.

Where is the liquid in a battery?

It's quite difficult to photograph the inside of the cells but the photo below is good enough to see that there is no liquid above the plates. In a battery in a good state of repair, the liquid level is usually up near the top of the cells, or more often over the top of the plates. Inside a couple of the cells.
