Can I seal up a NON AGM battery?

[chuck hahn]

Was wondering if anyone had thoughts on getting bsome plastics cement and doing away with the overflow and cementing the yellow caps shut on a regular styled battery.

Basically making it a sealed and non leakable battery??? Want to do this to eliminate little acid leaks on the battery boxes. Yes I have drain hoses and still theres the acid corrosion..and possibly on the bottom of swing arms as well.

Wow playing with fire there Chuck.
I would never do that but I am afraid of exploding acid filled boxes.

[chuck hahn]

never said i was gonna...but I am always thinking and pondering things such as this. They make sealed batteries, so whats the diff if someone seals up just a fill and go style battery? I was wondering so I posed the question. Besides if its goona go boom..then why dont sealed ones go boom??

But yes i remember that curiosity got the cats ballz in a wringer too!!!

been a long time since I was in a chem class so I dunno

Maybe theMess can explain it I think he is a chemist of sorts.

The answer is yes, the battery can burst open if you seal the vent on a conventional battery.

Years ago I saw a conventional car battery burst because is was shorted out.
Didn't go boom, the case just split open & all the battery acid leaked out.

I had a jeep battery explode and slam the hood into the windshield. I don't think I would take even a small chance with something I'm sitting on, unless maybe you think it might help you reach some high notes.

The sealed batteries have vents that will pass gas, but not fluid.

That must be a real confidence booster.

See...I didnt know that Steve. this is how I get edgiemicated around here!!!!

OK, Chuck, here is some "outside reading" to further your edjumacation:

From Wikipedia:

Absorbed Glass Mat
In the absorbed glass mat design, or AGM for short, the spacer between the cells is replaced by a glass fibre mat soaked in electrolyte. There is only enough electrolyte in the mat to keep it wet, and if the battery is punctured the electrolyte will not flow out of the mats. Likewise, the mat greatly reduces evaporation, to the point that the batteries do not require periodic refilling of the water. This combination of features allows the battery to be completely sealed, which makes them useful in portable devices and similar roles.
To address the formation of hydrogen gas during discharge, calcium is added to the plates to absorb the gas. This only works during slow discharges, and gas buildup remains a problem when the battery is deeply or rapidly discharged. To deal with these events, AGMs often include a one-way blow-off valve, and are often known as "valve regulated lead-acid", or VRLA, designs.
Another advantage to the AGM design is that the electrolyte becomes the separator material, and mechanically strong. This allows the plate stack to be compressed together in the battery shell, slightly increasing energy density compared to liquid or gel versions. AGM batteries often show a characteristic "bulging" in their shells when built in common rectangular shapes.
The mat also prevents the vertical motion of the electrolyte within the battery. When a normal wet cell is stored in a discharged state, the heavier acid molecules tend to settle to the bottom of the battery, causing the electrolyte to stratify. When the battery is then used, the majority of the current flows only in this area, and the bottom of the plates tend to wear out rapidly. This is one of the reasons a conventional car battery can be ruined by leaving it stored for a long period and then used and recharged. The mat significantly prevents this stratification, eliminating the need to periodically shake the batteries, boil them, or run an "equalization charge" through them to mix the electrolyte. Stratification also causes the upper layers of the battery to become almost completely water, which can freeze in cold weather, AGMs are significantly less susceptible to damage due to low-temperature use.

When a lead acid battery charges, water in the electrolyte is broken down into hydrogen and oxygen. A flooded plate battery must vent these into the atmosphere or pressure will build up and the battery will explode. (The gases leaving is why flooded plate batteries have to be topped off with distilled water from time to time.)

A sealed lead acid battery like an AGM or gel cell are able to recombine the hydrogen and oxygen back into water under normal charging conditions. The gas-only relief valve is more of a safety measure in case of overcharging.
