The bad thing is that the O2 forms at the positive plate and causes grid (and probably lead) oxidation--causing the plates to "grow" and put the positive post up and bulge the sides of the case. This can apply to the standard Lead Acid batteries out there (flooded cell, AGM, GEL)--As I understand.
How to tell if a golf cart battery is going bad?
Batteries that are going bad will expand and have bulges on the battery cases themselves. Also, batteries will be prone to leaking acid out of the case when they are on their last leg. Or lastly… Another way to see how your batteries are holding up is to test the voltage of the golf cart batteries.

What happens if you tighten golf cart battery terminals too much?
Each golf cart battery terminal has a resistance power and cannot cover more. Any excessive heat can quickly destroy the connection and terminals. On the other hand, if you end up tightening the connection more than what is required; you’re actually stretching the threads and pulling the posts out of the leads.
What would cause a battery to bulge?
Swelling, Bloated Battery Case Swelling usually happens when the battery is overcharged. When this happens, heat and hydrogen gas build up faster than the battery can allow them to dissipate, causing the outer casing to warp and expand.
What causes a sealed battery to swell?
You have known that when cell plates expand it eventually makes the battery to become swollen. Overcharging is one major cause of the expansion of the cell plates. The shorting of the battery terminals also causes the cell plates to expand. These two scenarios both heat up the cell plates inside the battery.
What does a swollen lead acid battery mean?

How does a battery work?
Your battery works by having two metals, a cathode and anode, react to each other to create chemical energy that we harness as electrical energy. With wet cell lead-acid batteries, these metals are kept in a liquid electrolyte, a liquid solution comprised of pure water and hydrosulphuric acid mixed to a set specific gravity. Other types of batteries typically use a gel, mat, or solid electrolyte to perform the same function. For the purpose of this topic however, the only battery we’ll be discussing is the traditional lead-acid battery, as this is the only type of battery for which you will have to worry about electrolyte levels.
