Identifying, Removing and Reusing It

There’s often a lot of talk about how to replace your dead car battery to get your car up and running again. That is indeed essential, and there are lots of experts who can tell you exactly how to perform all the required tasks successfully in just a few minutes. But what about the dead battery? How can you even know that it’s fully dead? And should you really just throw it away once it’s removed from your vehicle? These questions can be extremely important if you want to do a thorough job and be responsible regarding the environment.

Signs That Your Battery Is Dead

The main signs that your car battery is dying can be that your car doesn’t start up as easily anymore, especially in cold weather, or that jump starting it is increasingly less efficient. You may find the battery taking longer to charge with each jump, or notice that it cranks slower (or doesn’t crank fast for very long) or that it drains quickly when the radio, headlights or dome light are on. Once your battery is dead, it will no longer respond to charging at all. While it might still charge to some small extent, the charge won’t be enough to turn the car on or even to power your headlamps. At this point, you know your battery has truly died and it isn’t coming back again.

How to Test Your Battery Successfully

It’s essential to test your battery before declaring it dead. Even if jump starting your car doesn’t work, the battery may not be the culprit. There are other issues that could be at the root of why your car isn’t working, including a bad alternator, bad cables, faulty components in the charging system or even just a buildup of corrosion at the battery terminals. To test your battery you just have to use a basic multimeter and connect it to the battery terminals while using the 20V or 30V setting. Be sure to disconnect the ignition and take all other necessary safety precautions before considering this task.

The Benefits of Battery Jump Starting

If there are signs that your car battery is dying, but upon testing it you discover that it isn’t dead yet, then jump starting may help you get some extra juice out of it. The jump starting process is easy, and doesn’t require anything but a couple of special jumper cables and a little technical insight. In some cases, even if you thought your battery was completely dead, jump starting it might get it to work a little while longer so that you can make it home or to the nearest service. You don’t even need to find another driver who’s willing to give you a jump; jump boxes are available and can deliver a healthy jolt to a dead battery and get it going again.

When to Remove Your Dead Battery

When should you remove your dead battery, and is it all right to keep it in your car until you find a replacement, or until you find the time to get it disconnected? In most cases, it won’t be a good idea to leave your battery in the car for a simple reason: the battery might start to leak more corrosive material that builds up over time. This isn’t a problem if your battery is still in good condition, but if you live in a very warm or cold climate, or you’re going to store the vehicle outdoors, then it’s usually best to remove your dead battery as soon as possible. In any case, take it to an auto parts store where it can be disposed of properly.

Can Dead Car Batteries Be Reused?

Even if a “dead” battery can no longer produce the hundreds of watts necessary for your car to start, it doesn’t mean it’s useless. Quite on the contrary, your old car batteries can be recycled or even reused. Recycling plants are able to use all the materials, manufacturers can use them to build new batteries, and their cases and lead plates can be recycled. So, as you can see, your dead car battery is not as dead and useless as you might assume.
