How To Patch A Car Battery

1. Rejuvenate Car Battery With Vinegar

This protects your car from corrosive battery acid.Remove the cables from the battery terminals.Look in your owner’s manual to see whether your vehicle has negative ground (most do). If it does, use an adjustable wrench to first loosen the nut and bolt on the clamp that holds the battery cable on the negative terminal. (That’s the post with the little “–” or “NEG” on it.) If your vehicle has positive ground, loosen the cable with “+” or “POS” on it first. Remove the cable from the post and lay it out of your way.

Then remove the other cable from its post and lay that aside.If you have trouble loosening the bolt, grab it with one wrench and the nut with another, and move the wrenches in opposite directions. In this case, you don’t want to remove the bolts; just loosen them enough to release the cable clamps.Remove whatever devices are holding the battery in place. When you’re removing a bolt or screw, after you’ve loosened it with a tool, turn it the last few turns by hand so that you have a firm grip on it when it comes loose and it doesn’t drop and roll into obscurity.Remove the battery.When the battery is free, lift it out of its seat and place it out of your way.If the tray on which the battery was standing is rusty or has deposits on it, clean it with a little baking soda dissolved in water.Wear your gloves because the battery stuff is corrosive, and be sure the battery tray is completely dry before taking the next step! If your vehicle has negative ground, the positive cable goes back first. Make certain that the clamps holding the cables on the battery terminals are gripping the posts tightly.Take the old battery to a recycling center that accepts batteries.Batteries are filled with a toxic, corrosive liquid and must be disposed of properly. What’s more, old batteries are usually rebuilt into new ones, so just throwing one in the trash is doubly bad for the environment.

If you have your new battery installed when you buy it, the shop will recycle the old one for you. They’ll probably want to charge a few dollars for this service, but try to negotiate it into the price. You also can call your local recycling center for a referral.

Every time a driver turns the ignition key or presses the “Start” button, the starter motor is expected to crank the engine. This mechanism is caused by the 12-V flooded lead acid car battery, which is standard on virtually every vehicle on the road. Some cars carry a second battery, and trucks and RVs may carry a battery bank, linking several batteries. Similar batteries can be found in tractors, power equipment, motorcycles, powersports machines, snowmobiles, and solar power backup systems, to name a few.

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. Short car battery life, less than 3 or 4 years, can be related to several different problems, such as lack of use, corrosion, excessive deep cycling, electrolyte evaporation, damage, or charging problems. The are several things that can shorten the life of a car battery, and most of them are preventable. Now, we’re not talking about that “dead battery” that you get when the dome light was left on or the car hasn’t been driven in a month. 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. 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 2SO 4) in water. When discharging, the “” facilitates the flow of electrons, from the Pb plate to the PbO 2 plate, generating an electric current, which can be used to start the engine or illuminate the headlights, for example. Because of this chemical reaction, both plates become more chemically-similar and converting fully-discharged car battery plates to lead sulfate (PbSO 4), wherein lies the problem.​. So-called “soft” battery sulfation occurs practically every time you discharge the battery but, because it is usually immediately recharged, electron flow easily forces the opposite chemical reaction, resulting in dissimilar Pb and PbO 2 plates.

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, to charge and discharge the battery. Eventually, PbSO 4 crystal formation spreads, leading to cracks and short circuits within the battery, rendering it useless. Unfortunately, it is impossible to reverse hard sulfation, but it does one good to note, regarding products and services claiming to reverse sulfation, there is no real proof to back up their claims. Still, if you have a, there are several things that you can try to get yourself back on the road, even if it’s straight to a repair shop or auto parts store for a new battery. Vehicles started using these methods should not be shut off until a new car battery can be obtained, and a couple of these methods will finish off the battery, anyway.

Jumpstart: and a second battery, battery booster, or second vehicle might be enough to jumpstart the vehicle. The dead battery won’t accept a charge, though, so don’t shut the engine off! Note: Do not attempt to jump start a frozen battery, as it could explode. Thaw it out and attempt to charge it, first.

Distilled Water: If the electrolyte level is low, adding distilled water might be enough to fully-submerge the plates and enable a bit more reaction area. This might be enough to give the engine a few more turns. Epsom Salt: Epsom salt (magnesium sulfate or MgSO 4) can readily be found in grocery stores, home gardening centers, and drug stores. Adding a stronger acid to the electrolyte mix, such as Epsom salt, might be enough to tip the chemical balance, delivering enough charge to start the engine.

Dissolve 1 part MgSO 4 with 3 parts warm water, then add to each cell until the plates are covered by ¼” to ½” electrolyte. Aspirin: Imagine a vehicle out in the middle of nowhere, a remote camping trip, and all that’s available are a couple bottles of water and aspirin. Believe it, or not, Aspirin ( or C 9H 8O 4) can be used to chemically alter the electrolyte mix.

Crush and dissolve 12 Aspirin tablets, 325-mg or 500-mg, in about 6 oz of warm water, and add equal amounts to each cell. Add additional water to make sure the plates are covered.
