Last time your car battery died you probably just replaced it with a new one. I bet it was expensive and happened at the most inconvenient time. However did you know many car batteries can be saved, and if you learn how to recondition rechargeable batteries, not only can you bring your car battery back from the dead, but you will be more aware of its condition, and it is less likely to let you down again.
Check the battery:
Most dead batteries can be reconditioned, however first you must
check each cell, because if one is damaged it may not be possible, or
worth your while to attempt to recondition it. If you check each cell
individually it should read a voltage of approximately 2 volts. If any
read zero or considerably below 2 volts the cell is faulty.
To complete this test you will need to make a probe. You can make
this from a length of wire coat-hanger. Connect one terminal of your
voltmeter to the battery terminal post, and the other to the probe. Then
dip the probe tip into the electrolyte, to check each individual cell
One of the things that kills batteries is a build up of lead sulfide
crystals on the plates. The first step is to remove this using a charger
that has a circuit that provides a short high current pulse. This
breaks down the crystals, and dissolves them back into sulfuric acid,
leaving the lead plate clean again. Reducing this contamination will
rejuvenate your battery, and improve its ability to store charge.
Check the electrolyte:
Visually check the level of fluid, top this up with deionized water
until it is just covers the lead plates. You can also add a battery
conditioner, these are available from car parts stores, but if you don't
have access to this a teaspoon full of Epsom salts will work well too.
Once you have completed these tasks you should then fully charge your
battery using a good quality charger. Once fully charged re-test the
voltage across each plate as before. Now your battery is reconditioned
and should behave almost like new again.
Learning How to recondition rechargeable batteries will not only save
you money, by enabling you to bring your car battery back from the
dead, but can also be a great business. You can perform this task for
others, and charge them for your services. Making these batteries last
as long as possible helps the environment too, as the longer they are in
use, the longer they stay out of landfill.
