What is the best way to revive a car battery?
Usually, a jump start, booster pack, or battery charger is all that’s necessary to revive the car battery and get the car back on the road, but the damage has already been done. It’s the accumulation of damage that leads to the untimely death of the car battery, at which point it simply will not start the car.
What happens if a car battery is left out?
If the car battery is left discharged for long periods of time, “hard” sulfation occurs, the formation of lead sulfate crystals. As PbSO 4 crystals form, they gradually reduce the available surface area for chemical reaction, reducing the capacity to charge and discharge the battery.
What causes a car battery to die?
Car battery death, for the purposes of this article, refers to the battery’s inability to hold a charge, usually caused by sulfation. At its most basic, a car battery is constructed of alternating plates of dissimilar metals, usually lead and lead oxide (Pb and PbO 2 ), in an electrolyte bath, usually sulfuric acid (H 2 SO 4) in water.

How long do car batteries last?
Car batteries tend to last for several years, but lifespan depends on how they are used. The typical car battery, driven every day, properly charged, and never deep-cycled, could last upwards of 7 years, but that’s a best-case scenario. Most maintenance-free (read: replace on death) car batteries tend to last 4 to 7 years.

Step 1: Preparing the Battery
in sealed battery we will find cover on the top of the battery just remove it by little flat screw driver like photo when finish we will find 3 holes covered by rubber caps now we have to remove this caps too. ok now we will measure volts of this battery on my battery it's 0.76 volts only. that's mean the battery is completely dry from inside
Step 2: Fill the Water Inside the Battery
we need in this step to fill the battery with Distilled water to activate the acid again so refill it by syringe few time until the water come out from all holes and measure the voltage u will find it increased by mVolts that's good if not don't worry
Step 3: Mix Water With Acid and Charging
after filling the battery with the water we need to make sure it's mixed with dried acid inside the battery to reactivate it again so first we will charge it with 12 volts DC "i'm using ATX PSU " output is 10Amps u can use any charger 12V in maximum 9V in minimum ok now wait 5min until u see bubbles come out from the holes. if no bubbles come from any of 3 holes u have to reverse negative and positive and wait 1~3min At Maximum (it's Dangerous step don't leave the battery in this condition alone) ok now u must see bubbles come out from holes too fast like boiling cut off the power immediately and reconnect negative and positive right again.
Step 4
now pull the wasted water from the top of 3 holes by the syringe and let the battery charging Don't cover holes until it charge to 6.9V u should check it every 1 hour then dry it out by tissue and cover every thing Congratulations ur battery is working again Buy electronic components with cheaper and free shipping https://www.utsource.net / feel free to ask me? sorry about my bad english!!.

With the help of a funnel or the syringe pour a moderate amount of water into the first cell, wait for the mat to absorb it (unless you have a flooded battery, which has no mat), and fill up to just below the top of the plates.
Why is a battery unusable?
Some amount of sulfation is inevitable with charge and discharge cycles and is the main way in which a battery ages and becomes unusable. Improper charging and discharging (too fast or too deep) can lead prematurely to this.
How does a battery work?
As the difference neutralizes the available charge in the battery decreases. The key in rechargeable batteries is that this reaction is reversible, as applying a current into the battery (as opposed to drawing out from it) will restore the charge. Other electrochemical reactions may yield higher energy densities at the cost of not being rechargeable.
Why do batteries need venting?
Since the charging reaction releases hydrogen, lead-acid batteries need venting so they can let out the excess gas. Sealed batteries have valves to control the release, which leads to yet another name for sealed batts: VRLA for valve-regulated lead-acid
How much sulfuric acid is in a battery?
The sulfuric acid is only a small portion of the liquid inside the battery, around 25%. Therefore it needs to be dissolved in water so it reaches the entire area of the plates. As they have different boiling points, water can evaporate and separate out of the mixture, reducing its volume and effectively "drying out" the battery.
What are the components of a battery?
There are 3 main components to these batteries. Yes, it's lead and and acid. Specifically, a solution of sulfuric acid, lead plates and lead oxide plates. Lead plates are the negative. Lead oxide makes the positive, as the oxygen atoms bound to the lead "lack" electrons (electrons have negative charge), thus is "less negative"= positive. The sulfuric acid, dissolved in water, is called the electrolyte and carries electrons to and from these plates, and upon reaction with the lead, release electrons.
What is the purpose of a starter battery?
Their main task is to deliver a large current for a short time in order to turn the motor that cranks the engine for starting. Their normal use doesn't discharge them too much -- just one big, short dip that is recharged rather quickly. The alternator in the car keeps the battery charged as it runs the lights, stereo, ECU and all other electronics.
