If you have ever encountered a problem in your car when the battery just seemed to be unable to jump start your car? This happens most commonly in the winter and in the morning. After several trials, you finally get the car to start and then the next morning it behaves like it again. If your car battery was brand new or wasn't used for a long time, this might seem weird. Actually, you have just experienced battery sulfation.
If you cut open a battery (I wouldn't recommend this), it's actually made of metallic plates suspended in an electrolyte solution. In a nutshell, a battery creates voltage through electrical processes that happen between these plates and the solution. The only problem is, sometimes, the lead present in the plates tend to combine with sulfuric acid in the solution and becomes lead sulfate. This process is called sulfation.
This could happen to any battery. Those who are most prone to this kind of chemical reaction are those batteries who have been left unused for a long time like in storage rooms or just being displayed and not bought in a store.
The symptoms of battery sulfation are usually the same for most batteries. Your car starts with a little voltage then suddenly dies as if drained immediately of all its energy.
The product of the chemical reaction between the lead in the plates and the sulfuric acid, lead sulfate, actually has enveloped the plates in a crusty precipitate. This greatly reduces the plate's area in contact with the electrolyte solution subsequently lowering capacitance and voltage. In short, the plates become rusted with a different kind of rust, and this rust is getting in the way for your battery to function properly.
Fortunately for you, there are available devices in the market called battery desulfators which can rectify this problem easily. They simply remove the rust off of the plates and you'll find your batteries performing like new. Ask your mechanic about it.
