Reasons Your Car Battery Dies And What To Do About It
if you drive a gas-powered car, its battery provides the energy to turn your starter motor, crank the engine and get it running. it also powers components like onboard computers, clocks, radios and alarms when the engine is off.
batteries are compact, reasonably priced and provide a strong current to get your car started in all types of weather conditions. but they do eventually wear out a process that can be accelerated by things like cold weather, leaving the lights on or only driving short distances. lets look at how the battery works, and the problems that can befall it.
Why Does Your Battery Go Bad
most drivers dont realize their battery is going bad until their vehicle wont start. here are some of the many ways that batteries can fail.
leaving the lights on after shutting the car off
your headlights are a huge drain on the battery. without the engine running, the alternator cant recharge your battery. leave the lights on long enough, and youve got a dead battery. this can also happen if you leave the interior lights on, or if the trunk doesnt close completely.
Signs Your Cars Battery Is Dying
A failing batterys symptoms might be attributed to problems with other components, such as the starter, alternator, or other electrical parts. However, for our purposes here, we will assume all the listed symptoms are battery related.
Although a new battery failing is not unheard of, the older your battery, the more likely one of our warning signs below indicates it is failing or dead.

Conventional Batteries Vs Absorbed Glass Mat Batteries

AGM batteries use a bit of technology from the aerospace industry. They are more compact and lighter than conventional car batteries and are literally maintenance-free. Although they still use lead plates surrounded by an electrolyte solution, a glass-mat separator is between the lead plates. These fiberglass mats attract the electrolytes and store them in a dry state. As the need arises, the electrolytes transfer to the lead plates to create a charge.
Because of the glass-mat construction, AGM batteries discharge slower than conventional ones. In other words, they retain their charge longer. This makes them ideal for todays highly technological vehicles with many devices and electronics. AGM batteries also recharge more quickly than conventional batteries. Furthermore, because of the tighter packing of the battery elements, there is much less vibration than in conventional batteries. This design reduces wear and tear.
To sum up, the average AGM battery costs more, is more efficient, requires less maintenance, holds more charge longer, and will outlive a conventional battery by two to three years.

A Sudden Slower Start
When temps drop below 20 degrees, generally any cars starting cadence will slow down. Get below 0 and it gets even slower. If you notice this behavior suddenly and the temperature hasnt dropped a slow, dragging start suddenly begins, get your battery tested as soon as possible, and dont ignore it. Eventually, the car will not start.
If a slow starting battery seems to be able to take a charge and test fine, its likely that a parasitic drain or draw is discharging the battery while the vehicle sits, and the electrical system will need to be looked at.
Signs of a Bad Starter or Alternator vs. a Car Battery
A bad alternator will exhibit many of the same signs of a dead car battery: dim headlights, electrical issues, difficulty starting, and a frequently drained battery. An alternator, however, will often have its own alternator light on the dashboard. Also, your car may experience unusual rattles and sounds. If youve replaced your battery or are thinking about it, it may be a good idea to check your alternator at the same time.
A bad starter, however, has a whole other set of symptoms. When you try to turn the key, for example, youll often hear a single click rather than a few rapid clicks. You wont be able to crank the motor. You might hear a grinding noise or even see smoke when attempting to start it.
Of course, sometimes a battery is replaced and these other problems continue youll want to ask your mechanic and continued issues.
How Long To Charge With A Charger If Car Battery Is Dead
There are different chargers. The speed of charging depends much on the amps the charger is capable of showing. Usually, the best option is charging at lower amps and it will take around 8 hours to recharge the battery.
But make sure there are no drains and other problems. And also the battery is younger than 5 years. Otherwise, charging won’t help and next day you will probably have the same problem.

Is It Possible To Jumpstart A Completely Dead Battery
When a battery dies, how do you start it up again? After your battery has died, park your vehicle near another vehicle with fully charged batteries. Both cars must have the ignition turned off, and both jumper cords must be connected to the same computer. Two cars coming at the same time should be kept at a safe distance.
A drained battery can make driving in a car that is not well-maintained extremely difficult. When your cars battery dies, you immediately think of starting it, but you are unsure what to do when it does. When you have a dead battery, park your vehicle near another vehicle with fully charged batteries. You can expect the process to take between two and ten minutes on average. To be successful, some types of vehicles can take up to 30 minutes to complete. A large semi-tractor can successfully kick a tired engine. You can recharge a dead battery many times with thick jumper cables and large copper wires.

What Shortens A Conventional Car Batterys Life

A conventional car batterys multi-plate design allows for the shaking and vibrating of plates as the car drives along the road. All that jostling of the plates and sloshing of the electrolyte solution creates wear and tear.
Moreover, the electrolyte solution can leak out of the battery or boil out if the alternator malfunctions and overcharges the battery. Reduced levels of the battery solution can expose the lead plates, leading to corrosion and reduced battery efficiency.
Extreme temperatures can also shorten a batterys life and performance.

How A Car Battery Recharges
Although a reaction within the battery provides an extra burst of electric power to start the engine, a battery merely stores electric energy. An alternator is a key component in recharging and maintaining a batterys charge.
Once the engine runs, the alternator siphons off some of the engine output via a belt and pully. Thus, transforming mechanical energy into electrical energy. It then transfers that electric energy to the battery to recharge it.
A healthy new battery can repeat the discharging-charging process tens of thousands of times. However, it will eventually lose its capacity to recharge. Therefore a conventional battery will fail in three to five years under average conditions.
Heres the catch: A conventional batterys core efficiency lies in starting the engine. It will produce a trickle current to keep the headlights, radio, and so forth running for a limited period after the engine disengages. However, the battery is not engineered for that. Therefore, whatever charge is in the battery when the engine stops rapidly runs out, like the battery in your flashlight.

How To Choose The Right Car Battery
Your car battery is one of your electrical system’s most critical parts, so getting the right battery replacement is essential. But car batteries aren’t universal, and picking the right one can be confusing. So, what should you look for when it’s time to replace your battery?
First, your battery has to physically fit into your car’s battery tray. Batteries can vary in size! Consult your owner’s manual for battery size guidance.
Second, you want to be sure that you’re choosing a battery that will be powerful enough for your vehicle. Consult your owner’s manual and see what it suggests is the right number of cranking amps and choose a battery that fits within those parameters.
Third, you may need to consider cold-cranking amps or the amount of power it takes to turn over the engine in freezing temperatures. This is especially important if you live in a colder climate. It can make the difference between your car dying or starting on a cold winter day.
Finally, you’ll need to decide whether a maintenance-required or a maintenance-free battery is the best option for you. While a maintenance-required car battery, which requires regular electrolyte monitoring and top-offs, is cheaper on the front-end, maintenance-free batteries are a lot more hassle-free and don’t need much attention. Ensure you’re ready for the commitment if you decide to save money and go for the cheaper option.

Signs Your Car Battery Is Dead
No one wants to be stuck in a driveway or parking lot with a completely dead car battery that wont start again. A battery typically lasts between three and five years, depending on where you live, how often you drive the car, and your make and model. Many car owners may not realize how often they need replacing until major issues arise.
Can you get another year after jumping your battery? Were going to discuss how to tell if the car battery is dead as well as what to look for when trying to figure out if its completely gone.
How Much Does A Battery Replacement Cost
Compared to other vehicle repairs, changing out a battery is relatively inexpensive. But how much it costs depends on exactly what your needs are, and what type of battery you buy. There are over 40 different battery types on the market, all made by different manufacturers.
Traditional lead/acid batteries are around the cheapest youll find and can be bought for between $65 to $130. Absorbent glass mat batteries cost around $200 and these are better suited to powering sophisticated electronic systems in luxury vehicles. The more reliable deep-cycle batteries such as those found in RVs and boats can cost at least $200. At the top end of the market are lithium-ion batteries and these have a starting price of $1,000.
Replacing the battery isnt a time-intensive job so labor costs are kept low. A mechanic may charge you anywhere from $10 to $100 in labor to replace a battery, depending on if anything else needs doing at the time. To save money on labor, it is a job you can do yourself, but instructions need to be strictly followed to avoid crossing the battery terminals, causing the polarity to reverse and shorting out your vehicles ECU, which can also be a problem if you select the wrong battery for your car.

The Anatomy Of A Conventional Car Battery
All car batteries use lead-acid technology, as they have since 1859. Today, some conventional batteries provide removable caps for adding distilled water. Others are closed and dont require adding water.
In either case, they are composed of a series of lead plates alternating with plates of other materials. Surrounding the plates is an electrolyte solution of sulfuric acid and water. Engaging the ignition causes the electrolyte solution to react to the lead plates. Such a reaction discharges sufficient electric current to start the car.
