How to refurbish a dead car battery

Like many things, a car batteries’ performance degrades over time, and hundreds of dollars are spent on replacing dead batteries with brand new ones. Luckily, you needn’t waste your money; there’s an inexpensive way you can get a working car battery – just refurbish an existing one! This article will not only save you money on replacing the whole battery but will also demonstrate that you don’t have to buy expensive chemicals. You can get a car battery in great working order once again, simply by using water and salt. Here’s how you can bring your dead car battery back to life, in just a few short steps:

Safety first.

Over 2,300 people in the United States sustain car battery-related injuries including burns to the face and body, so don’t add to that statistic!

Before you even touch the battery, make sure you’ve taken the necessary precautions to avoid a nasty accident. As you’ll probably be aware, car batteries contain sulfuric acid, which is highly corrosive and can irritate the skin. It can also be highly flammable when not treated with care. We strongly advise following the below safety tips:

● Stay safe by wearing safety goggles, neoprene protective gloves, as well as a heavy duty apron to prevent acid from leaking onto clothes or exposed skin.

● We also advise you to work outdoors or a highly ventilated area, as batteries do release gasses that can be explosive when charging.

● Never leave the battery acid in direct sunlight or a hot location.

● Be aware that metal reacts with battery acid, so make sure that any metallic objects such as jewelry are removed and that only nonmetallic tools are used such as plastic funnels.

● Stay away from open flames when handling the battery, as even the slightest spark can cause an explosion.

To Begin…

Detach the battery from its cables and wash the outside with clean water and baking soda to prevent contaminating the inside of the battery. Make sure that all corrosion from the terminals and cable connections are scrubbed off. Next, mix 1/2 gallon of nearly boiling distilled water with 1/2 lb of Epsom salts and set aside, ensuring that the Epsom salts completely dissolve into the solution. This is the magnesium sulfate solution used to replace the battery acid.

Removing the battery cell covers

The battery cell caps can be removed by prying them off with a screwdriver. Remember to then drain the remaining water left in the battery as well as clean any residue around the exposed holes using a damp paper towel. Then, with a plastic funnel, pour the distilled water and salt solution into the cells until the lead plates are completely covered and then replace the cell caps. In order to ensure that all surfaces are completely covered by the solution, gently shake the battery around 10 times for even distribution.

Charging the battery

Now you need to attach the battery to the terminals and leave to charge on a slow trickle for 24 hours, repeating the process if you wish in order to prevent sulfur build-up and improve performance. Then, reinstall the battery ensuring that all connections are properly fastened. The battery should now be as good as new, and ready to use!
