How to bring dead lead battery to live again

Learn how to bring dead sealed lead acid battery into live again...

I already  tried this method with a lot of dead and expired batteries and 90% of them back to work again.

Battery is the thing which is used in almost every component in this technology age . so it is important to take care of it moreover it is very costly . so it is the need of time to recycle  batteries .
but you still can use a lead acid battery to a some extent with some less efficiency . but it is dangerous also so you have to take care of precautions ...
for this first of all take advice from your parents and take care of safety because battery contains sulphuric acid .
do these steps in a open area . 
The battery reconditioning method is a revolutionary technology which has recently come into notice. It is a very helpful method as it helps you to recycle old rechargeable batteries and use them.

notice : this method may be not bring the battery to full performance of the original condition but at my rate  the battery will work for 50%~70% of it.

   :  [you need]  :

-> 3cm syringe
-> voltmeter or multimeter
-> battery charger or power supply
-> crocodile cords "used with PSU "
-> Distilled water

and just follow some steps and then your dead lead battery will become again live with 50-70% efficiency...

   :  [ For Safety ]  :
->  use goggles and chemical gloves.
->  don't touch the water that came out the battery it's acid .


STEP [1] :->

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. BUT in 12V battery you will find 6 holes .the cause of dead of battery is loss of water during charging and discharging .

* water is used because it cause electrolysis.

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
you will find it increased by mVolts.
that's good,

for your knowledge i want to tell you why we use distilled water because it do not conduct electricity.
