What Causes A Car Battery To Die Quickly

Your battery stays charged by reusing the energy created from driving. If your car sits in the driveway for long periods of time you run the risk of killing your battery. Similarly, making a lot of short trips that dont allow the battery to recharge can strain the system. And last but not least, dont forget to turn your lights off we all know how that ends!

Why Does Car Battery Drain When Not In Use

Now, onto the main question, why a car battery may drain even if it is not being used?

A few things that may cause battery drain when not in use, include the end of the batterys life, loss of battery connections, a trunk light staying on or a power seat/window, or any other accessory with a bad switch or parasitic battery drain.

The current reading should be 0.03 amp when the engine is off.;

Apart from these, common causes of parasitic battery drain could be:

  • Warm boot light but no indication of light being on.
  • Car alarm could kill the car battery when not in use.
  • Chemical reactions inside the battery.
  • Faulty Relay, Dome light switch or alternator could be the culprit.

How A Car Battery Stores Energy

A quick flow of electrons from the terminals hit the car engine, making the alternator begins to supply electrons. The Voltas zinc-copper-saline battery does not reverse the electron reaction quickly like the Plantes lead-lead oxide-H2SO4 battery.

Excessive electrons generated goes into the solution, which gives it off to the terminals to produce electricity. These series of back and forth reaction has been used over time and can be said to be a dependable source of power for cars. Its so efficient that there hasnt been a need for a better method.

However, try to keep the environment harm-free by always recycling your old batteries.

How Do Mobile Mechanics Replace Car Batteries

RepairSmiths expert mechanics will be able to diagnose the problem and give you a clear picture of your batterys health. Do not continue to drive your car without getting your battery checked as it will more than likely die again, putting you back at square one. Replacing a car battery is better than being stuck at the side of the road. Book an appointment today.

The mobile mechanic will look for signs of a dead battery, and check how old it is. If its a new battery there may be something draining the power, and the mechanic will check this with a multimeter. Once the mechanic has determined that the draw is within the acceptable range, its time to replace the battery.

The negative battery terminal is removed first, and then the positive battery terminal is removed. The battery hold-down system is loosened or removed before the old battery can be taken out. After this is complete the mechanic will inspect the wiring and battery terminals for signs of corrosion, discoloring, or abnormal wear.

After the new battery is put in place, the battery hold-down system is reinstalled to keep the battery securely in place. Battery terminals are cleaned and anti-corrosion is applied to the terminals before they are reconnected. If required by the vehicle manufacturer, battery parameters are sent to the powertrain control module via the vehicles OBD2 port.

It starts with the alternator, the powerhouse of your car.; The alternator is connected to the crankshaft of the engine via a belt.; As the belt turns, it spins a rotor, surrounded by magnets, inside the alternator.

As the rotor passes the magnets it creates an AC current; which is converted to a DC current and then distributed throughout the vehicle.; Providing electricity to all of the electrical components in the car and then finally charging the battery.

Simple, right?

It’s Not Always The Battery

If your car won’t start, a dead battery is the likely culprit. However, there are numerous components that can cause similar symptoms. A faulty starter motor will make a click when you turn the key that sounds similar to a dead battery. If the alternator fails, the battery won’t recharge when the engine is on, leading to a no-start condition. Clogged fuel injectors or worn-out spark plugs can be a problem, and corrosion on the battery terminals, which prevents the flow of electricity, is common too. Fortunately, it’s easy to clean with a wire brush or steel wool.

With the popularity of all-electric vehicles soaring, there’s a good chance your next car will be powered entirely by batteries. But until then, follow these steps to keep your current gas guzzler in shape so that you never have to break out the jumper cables.

In this article from Jalopnik, they interview an electrical engineer who tested a 2019 Toyota Tacoma.; If you want a lot of technical jargon the article is worth a read.; But the summary is this.

You would have to allow your car to idle for possibly several hours to completely charge your battery.; There are many electrical systems in your car all vying for a little bit of power from the alternator.; What energy is left over to recharge the battery is very small.;;

There are a number of variables to this.; The amount of computer and electrical systems in your car, the health of your battery, and how much voltage your alternator is producing.

So allowing your engine to idle may put a small amount of charge on your battery, but that may not be the most efficient way to charge your battery.; The conclusion of his study estimated that allowing your car to run for only fifteen minutes or so would actually cost you more energy than you would gain.;;

Gasoline And Diesel Engine

Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as “SLI batteries” for this reason, for starting, lighting and ignition. SLI batteries are not designed for deep discharging, and a full discharge can reduce the battery’s lifespan.

As well as starting the engine, an SLI battery supplies the extra power necessary when the vehicle’s electrical requirements exceed the supply from the charging system. It is also a stabilizer, evening out potentially damaging voltage spikes. While the engine is running most of the power is provided by the alternator, which includes a voltage regulator to keep the output between 13.5 and 14.5;V. Modern SLI batteries are lead-acid type, using six series-connected cells to provide a nominal 12-volt system , or twelve cells for a 24-volt system in heavy trucks or earth-moving equipment, for example.

There are five important considerations when choosing the right battery for your car:

The Chemical Reactions In A Battery

In a typical lead-acid cell, there are positive and negative terminals. The positive terminal is the oxide of lead and the lead element the negative terminal. The catalyst known as the acid solution is the sulphuric acid , which forms lead sulfate with the terminals when the battery is in use.

Chemically stating the formula for the reaction

  • PbO2 + 4H+ + SO2- + 2e- -> PbSO2 + 2H2O
  • Pb + SO2- -> PbSO4 + 2e-

In the set of reactions above, reaction one absorbs electrons while reaction two gives off electrons. And the electrons can only be useful through the terminals that connect to the battery wires.
