What happens when a deep cycle battery dies?
If deep cycle battery is left discharged for long period of time, dendrite shorts between the plates can occur when the battery is recharged. The low resistance bridge in the shorted cell will heat up and boil the electrolyte out of the cell causing a high volumes of hydrogen and oxygen.
Can you revive a dead deep cycle battery?
You would have to cut it open to really see why it is dead, even then it can be not possible. If it sat discharged for a year, it probably cannot be revived. If it suddenly quit, probably a cell is shorted or a connector is open. Or the charger isn;t charging.
Is it bad to fully discharge a deep cycle battery?
Most deep cycle batteries are built to handle a 50% depth of discharge, but some can handle up to 80% discharge. Like opportunity charging mentioned above, this will prevent your battery from ever completing a full cycle, and will cause damage.
What causes a deep cycle battery to fail?
In hot climates, additional causes of failure are positive grid growth, positive grid metal corroding in the electrolyte, negative grid shrinks, plates buckling, and loss of water. Deep discharges, heat, vibration, over charging, under charging and non-usage accelerate this aging process.
Is the sulfuric acid in deep cycle batteries poisonous?
Deep cycle battery faq and battery information is on this non-commercial web site. DEEP CYCLE BATTERY FREQUENTLY ASKED QUESTIONS A word of caution: Lead-acid batteries contain a sulfuric acid electrolyte, which is a highly corrosive poison and will produce gasses when recharged and explode if ignited.
Which is the best test for deep cycle batteries?
And getting the maximum life out of your battery means maintaining it on a regular basis — so you can detect battery problems early resolve them quickly, easily, and cheaply. The most accurate test of a deep cycle battery will require an inspection of the battery’s fluid condition and voltage after charging service is completed.
Why do deep cycle batteries have thicker plates?
Deep cycle battery plates have thicker active plates, with higher-density active paste material and thicker separators. Alloys used for the plates in a deep cycle battery may contain more antimonythan that of starting batteries.[5] The thicker battery plates resist corrosion through extended charge and discharge cycles.
What should I do if my deep cycle battery goes bad?
Though the electrolyte in many deep cycle batteries is a combination of straight distilled water and acid, you’ll only ever want to add water. Assuming that all of this checks out, try charging the battery fully. You might want to remove any surface level of charge by putting it to use for just a few minutes to level it out.

How long does it take for a deep cycle battery to charge?
When the battery receives half to two thirds of the power you think it does, it will die sooner than you expected. Another mistake is not letting the batteries charge long enough. They typically need eight to ten hours to charge the battery. A fully discharged deep cycle battery may need twelve hours of charging when connected to the power grid.
