Batteries gurgling while charging?

Postby gitnby » Tue Oct 25, 2005 11:01 pm

Lifted seat and noticed a gurgling sound from one or more of the 6V batteries while charger was connected.

Is this normal? Never noticed it before!

Just added water the day before.

it's called boiling mine did it to. i think it happaens when you overfill the batts or don't charge before adding the water. after doing it twice (and spilling water) i think they got to the correct level as they have stopped.no noticeable damage to cart other than a little corroshon on the frame but mines a club car with an aluminum frame i don't think you'll have to worry about that as much(if at all) with an ezgo it's all explaned in
club car elec under what happend. hope this helps.

All batteries produce hydrogen gas when charging, but the older the batteries get the more gas they produce. Be careful with sparks.

Most gurgling

Most of the time it's doing it because you just added water to them. The water and gas are mixing together. The water you see on the tops of the batteries is it venting the gas off. The water filled the battery up and there is no room for the gas to go so it blows it out the vent.

I found this also some good info.
rely on the persons placing the batteries on the chargers, we recommend the use of plugs and connectors of different types or the use of keyed and color-coded connectors.


When a battery is charging, the electrolytic breakdown of the water in the electrolyte produces oxygen on the positive plates and hydrogen on the negative plates. This is normal. However, if a high charging rate is continued after the battery has been brought to its gassing voltage, the gassing becomes excessive, and abnormally larger amounts of hydrogen and oxygen gases are produced. The best indication of excessive gassing is a very noticeable ?bubbling? action of the electrolyte and high electrolyte temperature.

Hydrogen is a highly combustible gas and will explode on ignition when is connection in air reaches any level between 4 percent and 74 percent. (Below 4% the concentration is too weak; above 74% there is not enough oxygen left in the air to support combustion.) If you have reason to suspect excessive gassing, troubleshoot the battery and charging equipment. An unusually high usage of water indicates that excessive gassing is occurring.

I found this too

I found this also while searching about batteries.

Batteries start to gas when you attempt to charge them faster than they can absorb the energy. The excess energy is turned into heat, which then causes the electrolyte to boil and evaporate. The evaporated electrolyte can be replenished in batteries with removable caps such as most flooded deep-cycle batteries. Many car batteries are sealed and thus need to be replaced when their electrolyte evaporates over time
