sulphation battery zapper

hi all

how to make a 12V car battery which is dead reusable

what is the thing which is damaged due to time of usage

plz tell me
 

What usually happens is that the metal parts flake off and form a sediment in the bottom. When the sediment gets thick enough it shorts out the plates. This usually occurs on a very cold morning making you stand out in the cold weather for an hour waiting for the mechanic.

The best you can do is give the battery to a recycling center and buy a new one.
 

actually car battery is working but i want to use my old battery for small home use
and wanted to recycle it at own
 

Hi ehsan joon

i didnt want battersazi
i wanted to just make use of fazol battery
 

If there is any mechanical fault in the battery you can’t ´repair´ it! If the problem is sulphateing you might be able to dissolve the sulphate and recover the capacity of the battery. There are a few different ways to accomplish this, Ian mentioned one and here is another: https://www.electronics-lab.com/projects/power/036/index.html
 

i think that giving reverse current is working but how long

either i should use and charge the battery in opposite direction now
or just when sulphonation is reduced or finshed i should use it in correct polarity.................?
 

Reverse polarity isn't a good thing, just like flatulent said the best thing is to put the old one in a recycling center a buy a new one.

Engineering is the field for new new and new so i m trying to do the thing which i havent done and i shold know about those in electronics engineering
so i m trying as

ENGINEERS NEVER GIVE UP
 

It is dangerous to play with electrochemical cells! Open your eyes.Bye
 

hi
please try some of these step

1- wash all the cells with water then try to add new acid solution and charge

2- if the voltage still low check each cell (if short or open) if there is short try dischage battery with cable then charge this may burn the short

3- if the cell is dead you can replace the dead cell with other good cell from other dead battery
