It may come as a surprise to discover that used car batteries are a viable option. Batteries are expensive, and regular replacement is necessary. To determine if going the used route is a good idea, it’s necessary to understand what a battery is, why a used battery can be a good choice, and learn where to find those low-price deals.

What a Car Battery Actually Is

Most drivers understand that their vehicle requires a car battery that is charged up and able to start the engine and run the lights. These batteries are rechargeable. They must have a sufficient amount of power to restart the engine after it is shut down. Once the engine is running, an alternator is used to recharge the battery as needed so it can power the lights. A full discharge damages the battery, so it should always remain highly charged so it has maximum power available to turn the engine over. You can learn more at about how engines use battery power.

Wet batteries typically have six cells made using lead-based parts as cathodes and anodes. An electrolyte solution (typically sulphuric acid) conducts electricity within the battery. Keeping the interior plates fully immersed in the electrolyte solution limits internal damage and effectively uses the entire surface area to create a big enough charge. In the past, each cell could be opened so that evaporated solutions could be replaced. Most batteries are closed now and require little in the way of maintenance. Other alloys than lead-based ones are also used. The batteries used in hybrid and electric cars are quite different and take advantage of lithium-ion reactions. They are not discussed in this article.


Why Buy a Used Battery?

There are two really good reasons to buy a used battery. First of all, used batteries can be reconditioned and last for many months. These batteries are a great bargain. In some cases, a car may have been in an accident. These wrecks are taken to the junkyard and parted out. Many batteries that show up there are in like-new condition. An examination of the used battery for sale can determine how old it is and whether or not the battery was damaged when the car was damaged. These batteries are much more affordable than new ones.

In addition to saving money, reusing batteries protects the environment. New batteries won’t have to be manufactured, and old ones won’t damage our limited resources. Keep in mind that there are distinct requirements for the disposal of batteries, which will be talked about later. However, any time a product finds a new use, that is a win for the environment. With so much waste, knowing that there is a reasonable way to reduce our use is comforting.

Where to Look for Used Batteries

Used batteries are easy to find once a person learns where to look. Many auto parts stores sell them after the batteries are returned and reconditioned by the staff. Before restoration is done at these stores, the battery is first evaluated to see if it is worth saving. Many car repair shops that sell new batteries also sell old ones. Not every car repair shop will, but smaller shops are more likely to do so. Some car repair or auto parts sales companies specialize in used parts. They purchase parts, recondition them, and either sell them or place them in a different vehicle. Be sure to deal with a knowledgeable staff.

Junkyards are wonderful places to find used batteries, as mentioned above. Be prepared before heading out to the yard. Some junkyards will pull the battery for their customers. Others insist that people bring their own tools and pull the battery themselves. Warranties are generally not available at junkyards. However, companies that recondition used batteries on a regular basis will often offer an in-store guarantee. It’s best to find this out before purchasing any used battery.

How To Properly Dispose of a Battery When It’s Life Ends

Once the battery has finally ended it’s effective life, it is time for disposal. Batteries may never go into landfills because of the potential risk of heavy metal contamination. There is no risk of environmental damage as long as batteries remain sealed. However, time does take its toll and, eventually, corrosion sets in. Heavy metals cause serious health risks to major organs, so the EPA is quite strict when it comes to breaking a battery down into its component parts. Those component parts include nickel, cadmium, and other high-risk materials.

Expert training is required to properly dispose of batteries, so most households will never have to do the nasty work. Since most battery sellers are equipped to break the batteries down or use a service that does it for a fee, simply return the battery to the place where you purchased it. In some cases, there will be no fee if a new battery is bought at the time. However, if you don’t need a replacement, there will be a minimum charge. Use an internet search to find a dumpsite near you.

Used batteries are a surprising way to save money for car owners. The batteries used in most vehicles are very different from the lithium-ion batteries typically used in electric or hybrid vehicles. It is important to select a used battery that has either been reconditioned and checked for damage before purchase. In addition to saving money, these batteries also help to protect the environment. They are readily available, even though most car owners are not aware of their existence. They can be found at auto parts stores, car repair shops, and in junkyards. However, when a battery is purchased from a junkyard, the buyer can expect to do some of the work.

Once a battery life has ended, they absolutely must be properly disposed of. Most batteries are disassembled by experts and the various parts are separated. Used batteries turn out to be a good solution for many people.
