Why Does The Battery Die Again After A Jump Start
Here are some reasons why your car battery wont hold a charge after a successful jump start:
- The car wasnt driven long enough for the battery to recharge fully
- The vehicle charging system has a problem, like a bad alternator or voltage regulator
- An electrical system was left on, draining the battery
- The battery is too old and just cant hold a charge
If A Car Battery Is Completely Dead Can It Be Recharged
Yes, you can fix a completely dead battery. All you need is a bit of Epsom salt and some distilled water to clear out the sulfur deposits. Epsom salt dissolves all the build-up and cleans out the terminals.
Pour a tablespoon of the solution into each of the six cells of the battery. Attach a small tickle charger afterward and your battery would be good as new.
Quick note: keep the tickle charge on low power. You dont want to blast the newly revived battery with a charge.
Connect The Jumper Cables
Identify the positive terminal on the dead battery. Its usually marked with a symbol or the word POS. The negative terminal will have a sign or the word NEG.
Now, do this:
- Attach a red jumper cable clip to the positive terminal of the dead battery
- Attach the other red jumper cable clip to the positive terminal of the donor battery
- Attach a black jumper cable clip to the negative terminal of the donor battery
- Attach the other black jumper cable clip to an unpainted metal surface on the dead vehicle

Signs Your Car Battery Is Dead
Posted on in Auto Repair
If youre like most Americans, then you will probably wait until your car battery is completely dead before you change it. This approach, which has been seen ever since batteries were invented, is definitely not the safest one. A survey of 1,000 drivers, sponsored by Erics Car Care, showed that 53% of the group waited until they were stranded by a dead battery and then had to call for roadside assistance.
Here at Erics Car Care, we get a lot of calls for dead batteries. Or customers asking us how do I know if my car battery is almost dead?. And more often than not, the battery is already dead.
While a battery is a simple, relatively inexpensive device, it is essential. If it doesnt work, you arent going anywhere. So it pays to check your battery regularly and replace it BEFORE it dies.
Below is a list of signs your car battery is dead or close to dying:
#1 Engine cranks, but doesnt start
If your engine cranks or turns over when you turn the key, but it wont start, your battery is most likely the problem. There is a chance it could be your starter, but 94% of the time, its really your battery, even if the car is cranking fairly forcefully. And although your car battery tester says your battery is good, it can still be a few volts shy of what your vehicle needs to run efficiently.
#2 No sign of life anywhere
#3 Your Car Starts Perfectly Fine One Day, Then The Next It Doesnt
#4 Cold Cranking Is Hard Work
How Much Does A New Battery Cost

How Many Miles Can I Get Out Of A Car Battery
Onaverage, a battery lasts about five to six years, but mileage differs fromdriver to driver. One thing we know for certain is that batteries dont lastforever. Numerous factors can influence the lifespan of a battery:
- Where you live and your drivinghabits.
- How you use your carsaccessories.
- The condition of your chargingsystem.
- How extreme the weather gets.
What If The Engine Cranks Normally But Doesnt Start Or Run
If your engine sounds like its turning over normally and just fails to start, then the problem probably isnt a dead battery. You will typically hear a difference in the speed that the engine turns over if the issue has to do with a low level of charge in the battery. So an engine that cranks normally and just fails to start or run indicates a totally different problem.
Most of the time, an engine that seems to crank normally without actually starting has either a fuel or spark problem. The diagnostic process can become very complex, but it always starts out with checking for spark at the spark plugs and checking for fuel at the fuel injectors or carburetor.
In some cases, even parking on a hill with a near-empty gas tank can cause this type of problem, since doing so may shift the gas away from the fuel pickup.

Battery Or Alternator: Whats Causing The Problem
Starting and running an engine, in its simplest form, is a three-step process. First, the battery delivers a jolt of electricity to the starter. This starts the engine running, which puts the alternator into action. Finally, the alternator completes this cycle by charging the battery.
Using the process of elimination, find the culprit by bypassing the batterys role and jump-starting your car. If the engine starts but dies immediately, your alternator probably isnt keeping your battery charged. If a jump starts and keeps your car running, but the car cant start again off of its own power, a dead battery is likely your answer.
What To Do If You Think You Have A Dead Battery
If you have a AAA membership or roadside assistance, call for help. Many roadside service operators can make a basic diagnosis of your problem and jump-start your vehicle if necessary. If a jump-start doesn’t work or you have a problem other than your battery, they can tow you to a mechanic’s shop.
If you believe you have a dead battery in your car, you can jump-start the car with access to good quality jumper cables and someone with a running vehicle who is willing to lend a hand. Consult your owner’s manual for instructions specific to your vehicle.
“If using a booster car, start its engine and let it run for a few minutes before trying to start your car,” said Reina. “Your cars engine should crank and start. If it starts and stalls, turn the key off, wait a few moments, and try again. It may help if the owner of the booster car slightly raises their cars idle speed while you are cranking your car. If your car does not crank , or only elicits a clicking sound, the cables clamp connections may be weak. Turn off the engine of the booster car and try wiggling each clamp in turn. You may have some dirt or corrosion preventing a clean connection.”
If you aren’t sure why your car won’t start, it’s best to consult a mechanic. Having a professional diagnose the problem will help you avoid needlessly replacing expensive parts.

How To Fix A Dead Cell In A Car Battery
On identifying a dead cell in your car battery , you should immediately replace it with a new one. However, there are certain ways to fix dead car battery cell. Following is a step-by-step guide that will help you:
- First, you need to locate the dead cell in your battery with the help of a specific gravity tester. The ideal specific gravity is 1.26. If it reads more or less than that, it means that the cell is dead. A rule of thumb is that there should not be a difference greater than 0.05 between each cell reading.
- Once you have located the dead cell, cut the battery top and remove it.
- Wash the removed cell chamber with a solution of baking soda in water to remove any dirt or deposits accumulated on it.
- Now place a separator between the positive and negative plates to make the cell out of it.
- To make the terminals of the cell, use molten old lead plates.
- Weld the terminals of the cell to the terminal of the battery.
- Fill in the 1.26 specific gravity electrolyte.
- Finally, recharge the battery for at least 12 hours then are ready to go. For Video .
Here comes a question. Does dead car battery recharge itself? Remember that a battery, dead, or working cannot charge itself. Using a dead car battery is quite hazardous, so I would suggest quitting its use unless you like trouble.
What Does A Car Battery Power
The most important job that a car battery performs is starting the engine. Once the engine is running the alternator generates more energy, which is stored by the battery. However because the alternator does not run while the cars engine is switched off, so the ignition system uses power that is stored in the battery.
While the engine is switched off, the power stored in your cars battery is used for powering all of your cars electrics including the radio, windows or anything you might be powering or charging from your cars cigarette lighter, which is why you dont want to run any electrical systems in your car for too long while the engine isnt running you run the risk of draining the battery and then not having enough power left to start the engine again to recharge the battery!

How Can A Car Battery Be Dead In The Morning And Fine Later
The common scenario here is that your battery seems dead, but your car starts fine after jump starting or charging the battery. Your car may start fine all day, or even for several days, and then it suddenly fails to start again, usually after it has been parked overnight.
This type of problem may indicate a bad battery, but the underlying problem probably has nothing to do with the battery. In most cases, youll find that your electrical system has a parasitic draw that slowly drains your battery down to nothing. If the draw is small enough, youll only notice the effect after the car has been parked for an extended period of time.
Other issues, like corroded or loose battery terminals and cables, can also cause this type of problem. In any case, the fix is to get rid of the parasitic draw, clean and tighten the battery connections, and then fully charge the battery.
Cold weather can also cause this type of problem because excessively low temperatures reduce the ability of a lead-acid battery to store and deliver power. If you run into a situation where your car needs a jump start after being parked outside overnight, but its fine after being left in a parking garage all day while you work, then this is probably what youre dealing with.
