The clock, radio, and alarm system all receive electricity from the battery even while the car is not moving. Your battery shouldn’t be significantly impacted by these items. When a car is not in use, factors like interior lights, door lights, or even faulty relays can deplete the battery.
The alternator recharges the battery while your engine is running, so you usually don’t have to worry about it dying while you’re blasting the radio on the way to work! However, while the engine is turned off, the alternator is unable to replenish the battery, allowing minor electrical malfunctions to completely empty your battery. These electrical glitches put stress on the battery, which is referred to as a parasitic drain.
By turning off all of the lights and ensuring that your doors, glove box, and trunk are completely closed and secured before exiting the vehicle, you can help prevent parasitic draws.

What continues stealing power from my auto battery at night?
The aforementioned issues are the most typical causes of batteries that won’t keep a charge. If you are still unable to identify the issue’s root cause, another system might be the problem. For instance:
- Look for issues in the circuit (loose, disconnected, or broken wires), a failing alternator, or a loose or worn-out alternator belt when inspecting the charging system.
- Have the battery inspected if it appears to malfunction in extremely hot or cold temperatures. Under these circumstances, faulty or old batteries are more prone to malfunction.
- Start there if you’ve just installed or upgraded equipment, added a new electronic item, changed out wiring, or altered a circuit.
- The beginning system can have an issue. Your battery may be drained by an extreme current draw brought on by a short circuit.
- Your battery, especially an old one, can eventually suffer from making too many short excursions (less than one mile). The battery’s lifespan is shortened because it can’t fully recharge.
- Excessive battery depletion while cranking is another potential result of engine performance issues.
What is the price of a Volkswagen Touareg battery?
A new battery for a Volkswagen Touareg typically costs between $430 and $460. While parts are priced at $317, labor expenses are predicted to range between $113 and $143.
How can I know if my battery is being drained by my alternator?
Your pride and joy is your car. You treat it as if it were your infant. You clean it, change the oil, and make sure it’s in excellent condition. It is therefore terrible when you turn the key and nothing happens. Though it might be the alternator, you might be thinking it’s the battery. Here’s how to determine if your battery is being drained by the alternator.
Open the hood and start the car to see whether your alternator is zapping your battery. Remove the negative battery cable while the engine is still running. The alternator is most likely defective if the car stalls or dies.
Can a blown fuse deplete the battery in a car?
Ever wonder what could drain a car battery when it isn’t running? Or does the battery in your automobile constantly dying over night? Alternately, as you prepare to start your day’s activities and get into your car to leave, the most aggravating thing occurs. It won’t turn on! Well, like you, many drivers who have encountered this annoyance at inconvenient times have this nagging question.
Don’t get me wrong; you might not need to worry as much if this is the first time your car battery has discharged when the engine is off. not yet, at least! But you must be certain that something is seriously wrong if the battery has discharged more than once while your automobile is not in use.
You are correct; it is not typical to continually experience a dead battery. The engine should theoretically start when you turn on your automobile thanks to the car battery.
Once this has occurred, the alternator ought to turn on and start charging your battery while you are driving, bringing it to a full charge. As a result, your battery ought to be fully charged and prepared to start your car’s engine the following time when you park and turn off the engine.
How, therefore, can your fully charged battery discharge when the engine is off and prevent your car from starting? Seven potential causes of your current car battery issues are listed below:
Why is the battery in my car suddenly losing so much power?
Like conventional cars, electric cars can have parasitic drain, broken batteries, and severe temperatures that induce battery depletion. Faulty charging is another possibility for the battery drain in your electric vehicle. A faulty charger could be the cause of your electric car’s battery not being charged.
What does a parasitic drain look like in my car?
Within a few minutes, you should be able to identify the cause of your battery drain. This project doesn’t require further assistance, but it may be helpful. Keep in mind that you may have many fuse panels, depending on your car. Most cars feature at least two fuse panelsone within the passenger compartment and one under the hood. There may be several fuse panels located in various places inside some foreign autos. You might wish to consult your owner’s manual or a discussion board.
Step 1: Remove Negative Battery Cable
The negative battery cable should be taken away from the battery post using the proper tool or socket. In our situation, the battery terminal was secured with an 8mm bolt because we were working on a 2000 Ford Explorer. Either the positive or the negative cable can be used for this test or diagnosis, but the negative cable is significantly safer. Negative wires can be grounded without issue, but positive wires may damage devices, including your multimeter.
Step 2: Check the Draw Across the Negative Cable and Battery Post
Make sure your multimeter is turned on, Amps (A) selected, and set to DC (Direct Current). An image resembling a solid line with dashes underneath should appear. You don’t want AC (); this is for the electricity in your house. Decide whether to start with Amps or mA (milliamps) because you will likely have the option; ideally, 10A or 20A. On the multimeter, check that the wire leads are in the proper position. The multimeter should have a diagram that shows you where to connect the test lead wires.
Your multimeter will be connected in series with the current draw or battery drain. This implies that the multimeter will be used to measure the current draw. In our scenario, the multimeter was receiving power because we had a 4.4 Amp draw. Make sure your leads and dial are in the appropriate places.
Put one of the multimeter’s wire leadsit doesn’t matter which oneon the negative battery post and the other on the battery cable that has been detached. The amount of Amps actively depleting your battery should be displayed on the multimeter. To keep the multimeter leads attached to the battery terminal and battery wire, use zip ties or tiny clamps.
Tip: The battery will draw roughly 50 milliamps of amps while a vehicle is working normally.
Turn Down the Brightness
Reduce screen brightness for one of the simplest methods to extend battery life. Although decreasing the brightness seems like a no-brainer, studies have proven that it actually does make a difference. So start doing it now if you haven’t already! Additionally, it’s a good idea to turn on “Auto-brightness” so that the screen will automatically reduce if you’re in a dark environment.
Mind Your Apps
Numerous well-known apps are notorious battery hogs, especially those with plenty of graphics or sounds. The greatest offenders are video games, especially free ones with adverts, so save playing Angry Birds for when you’re close to a power outlet.
And never just minimize your apps; always completely shut them down. Battery drainers may include background-running applications. To achieve this, double-tap the home button to see the running programs, then press and hold one of the icon until it begins to move. To exit an app, tap the “-” symbol in the upper-left corner of the icon.
Download a Battery Saving App
If you’ve stopped playing the games completely but your battery is still draining, there might be less visible apps that are to blame. Use an app like BetterBatteryStats or Battery HD+ to monitor your phone’s performance over a few days and identify the apps that are the biggest drains on its battery.
Turn Off the Wi-Fi Connection
Your phone is actively searching for a hotspot as soon as your Wi-Fi is turned on. While joining the nearest Wi-Fi network can help you save money on your data plan, it can also significantly deplete your battery. Turn off the Wi-Fi and only use it when necessary.
Turn on Airplane Mode
It’s a terrific technique to save battery life when you need it to switch to airplane mode when you’re not only flying in the open sky. The drawback is that you won’t be able to send or receive texts, make calls, or access the internet, but it can be beneficial to save your battery life for when you really need it.
In order to prevent your phone from depleting itself attempting to obtain a signal, using airplane mode when you’re in an area without service, such as underground on the metro, is a wonderful idea.
How long does a battery in a VW Touareg last?
Battery life for the VW Touareg is typically between three and five years, however it might vary according on driving behavior, battery type, environmental factors, and more.
How can you tell if your alternator is defective?
As was already noted, if your engine is difficult to start, your alternator may not be charging the battery. As a result, when you turn the key in the ignition, all you’ll hear is a clicking noise rather than your engine’s purring sound.
On the other hand, if your car repeatedly stalls out while you’re driving, it can mean that the alternator isn’t supplying the spark plugs with enough power to keep the engine running.
How can you tell if your alternator is operating properly?
Running your automobile while removing the positive battery connection is a quick test to determine whether the alternator is functioning properly. You most likely have an alternator issue if the vehicle stops. Checking your interior lighting is an easy additional exam.
What’s zapping my battery life?
Options > Battery > Usage information
Android comes with capabilities built-in to monitor this very thing, so there’s no need to keep track of which apps you use while attempting to determine what’s draining your battery charge. Open Settings and select Battery from the menu. With the most power-hungry apps at the top of the list, click Battery Usage next to see a breakdown of all the apps that are using the most of your battery.
Some phones will display the duration of active use for each app, while others won’t. It just makes sense that if you’ve spent an hour browsing Instagram, it will have a negative impact on your battery life because utilizing the screen for so long drains a lot of power.
Since it isn’t simply software, as we just explained, other phones (like Huawei and Honor) will also show you how much each physical component has used the battery. However, our test phone here doesn’t display this information.
When you tap on an app, a new page will emerge with information on the program’s background activity as well as how long you have used it personally. If you notice an app with a high score in the latter, it may be having issues that are shortening your battery life.
You can either utilize the Background restriction or Battery optimization tools to lessen the influence the app is having on your battery life, or you can select to Force Stop, which will terminate the app until you restart it.
The former will prevent the app from operating in the background, but use caution as things like email and messaging apps require these rights to regularly check for new communications.
While this can be a little daunting owing to some of the items that show, tapping on the Battery Optimisation option opens a list of processes and apps that you can utilize to enhance battery life. Going back to Settings > Battery and selecting the Battery Saver or Adaptive Battery settings, which allow Android to manage things on your behalf, is what we’d advise doing instead.
Try these out and see if they work to improve the situation over the course of the next day or two. If they do, you’ll know you’ve identified the problem. Moreover, you can read our article on
