glen Posted June 11, 2014 Report Share Posted June 11, 2014 My one year old deep cycle is bubbling when it is unhooked from everything. It has about a teaspoon worth of electrolyte on the top leaking out of the vent caps. What's wrong with this battery. Link to comment Share on other sites More sharing options...
NANUK Posted June 11, 2014 Report Share Posted June 11, 2014 Try cleaning the cables/connectors and battery terminals, make sure all connections are tight. Check water levels, should be just below the neck of each vent hole. Make sure you use face protection. Boiling is usually caused by over charging or a slight short, I have a feeling you need a new battery. Link to comment Share on other sites More sharing options...
glen Posted June 11, 2014 Author Report Share Posted June 11, 2014 It's not connected to anything. Small short inside the battery? Thanks for your help. Link to comment Share on other sites More sharing options...
Fisherman Posted June 11, 2014 Report Share Posted June 11, 2014 Internal short, sometimes crud from the plates will short it out, I have one like that. Link to comment Share on other sites More sharing options...

Garnet Posted June 12, 2014 Report Share Posted June 12, 2014 A load testers will tell the story. Likely 1 dead cell. You charge it and get 13.7 put load on and it's 10-11.5 dead cell. Replace battery. Link to comment Share on other sites More sharing options...

doubleheader Posted June 12, 2014 Report Share Posted June 12, 2014 If you want to avoid leaky battery acid issues in the future you may wan to consider AGM type batteries. Link to comment Share on other sites More sharing options...
