How To Keep Your Battery From Repeatedly Dying

What To Do When Your Car Battery Dies

While its true that every single battery has to die eventually, the key to prolonging the life of a lead-acid battery like the one in your car is to keep it well maintained and in good working order. If youre dealing with a situation where your battery goes dead over and over, theres a good chance that every time it dies like that, the ultimate lifespan of the battery is shortened.

By keeping on top of corrosion, making sure that the battery connections are tight and secure, and not allowing the electrolyte in a non-sealed battery to drop, you can actually help your battery last much longer.

There may not be a lot you can do to avoid other issues, like a sudden parasitic drain, but dealing with that type of problem in a timely manner can also help prolong the life of your battery. A battery tender can also help in the winter if it gets especially cold where you live, or if you dont plan on driving your car for an extended period of time.

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

What Happens If The Alternator Is Still Working

Does your car still work if the battery is weak, but the alternator is still operating perfectly? The short answer to this very relevant question is yes! Batteries go through a sickness process before they actually die as we explained above.

Slowly over a period of time, the car becomes ill, lights will start to dim when the car is stationary, and it will turn over slower.

For a car to work with a very sick battery it would require enough power to start the car and then you must shut down every electrical device that you possibly can on the vehicle. Obviously, this is not possible at night and also not an option in searing heat.

A dying battery will produce a huge load on an alternator, one that will be too intensive and eventually cripple the car. Needless to say, a dying battery can also wreck a healthy alternator, which is the reason why both often need to be replaced at the same time.

How Does A Car Battery Die

The are several things that can shorten the life of a car battery, and most of them are preventable. Now, were not talking about that dead battery that you get when the dome light was left on or the car hasnt been driven in a month. Usually, a jump start, booster pack, or battery charger is all thats necessary to revive the car battery and get the car back on the road, but the damage has already been done. Its the accumulation of damage that leads to the untimely death of the car battery, at which point it simply will not start the car. Car battery death, for the purposes of this article, refers to the batterys inability to hold a charge, usually caused by sulfation.

At its most basic, a car battery is constructed of alternating plates of dissimilar metals, usually lead and lead oxide , in an electrolyte bath, usually sulfuric acid in water. When discharging, the battery acid facilitates the flow of electrons, from the Pb plate to the PbO2 plate, generating an electric current, which can be used to start the engine or illuminate the headlights, for example. Because of this chemical reaction, both plates become more chemically-similar and converting fully-discharged car battery plates to lead sulfate , wherein lies the problem.

How Dead Is The Battery

Dead car battery: what to do and warning signs

This is a question that is often asked when people are trying to determine if they need to replace their car battery. The answer is not always straightforward, as there are a few factors that can affect how long a car battery will last.

One of the most important factors is how often the car is driven. If a car is only driven a few miles a week, the battery will not get the chance to fully charge and will slowly discharge over time. This can shorten the batterys life significantly.

Another factor that can affect a batterys life is the temperature. Hotter climates will cause the battery to discharge faster, while cooler climates will allow the battery to last longer.

So, when trying to determine if a car battery is dead, it is important to consider how often the car is driven and what the temperature is like. If the battery is more than three years old, it is probably time to replace it.

    The other important issue is that when the voltage of a car battery drops to about 10.5 volts, that means the lead plates are almost entirely coated in lead sulfate. Discharging below this point can permanently damage the battery. It may no longer be possible to fully charge it, and a full charge may not last as long.

    Leaving a battery dead can also cause serious problems, as the lead sulfate can eventually form into hardened crystals. This buildup cant be broken up by a regular battery charger or the current from the alternator. Eventually, the only option is to replace the battery altogether.

    The Role Of Your Cars Battery

    All of the electricity in your car is pulled from the battery. In other words, any components that require a current are reliant on your battery. It will be hooked up to your battery directly and will keep taking power for as long as the part is running.

    Corrosion On The Connectors

    How Long Does A Battery Last

    • Batteries normally have a maximum life expectancy of two or three years, even if manufacturers say they will last five years or more. If anyone sells you a super long life model, keep your receipt and get a warranty. Especially if you use your battery for a lot of accessories its unlikely to last as long as promised.
    • Optimally, you should replace your battery every two and a half years or sobefore you have problems.
    • Other things can affect its lifespan, since a battery relies on other parts to do what it does. It needs help from your alternator, your starter, the solenoid, the battery terminals , and its own cables . Though as I argue below, the problem is very often just age, Ill admit it can be something else.
    • The age of a battery, even if it doesn’t show any obvious signs of being old, can affect your vehicle in negative ways that will slowly add up to a big repair bill. Thats why I recommend replacing it before you have problems with it.
    • Your ordinary battery doesn’t do so well in extremely cold weather, which may be why you have to pump the gas, or turn the key back to prime the fuel pump, or do a little dance to get the truck or car started on chilly mornings.

    Cause #: Faulty Alternator

    Alternators are installed in automobiles to power the electrical system once the engine is turned on. It is driven by the crankshaft through the serpentine belt. Another function of an alternator is that it charges the battery after ignition. If your car has a faulty alternator, then it could drain your battery since it is not charging properly.

    Driving short distances is also a cause for draining your battery. An alternator needs some time to charge your car battery after ignition. As such, short trips are bad for your car battery since they will not fully recover. You should leave your car running for at least 10 minutes after a short trip to avoid car battery dies overnight,

    Every time a driver turns the ignition key or presses the Start button, the starter motor is expected to crank the engine. This mechanism is caused by the 12-V flooded lead acid car battery, which is standard on virtually every vehicle on the road. Some cars carry a second battery, and trucks and RVs may carry a battery bank, linking several batteries. Similar batteries can be found in tractors, power equipment, motorcycles, powersports machines, snowmobiles, four-wheelers, and solar power backup systems, to name a few.

    Car batteries tend to last for several years, but lifespan depends on how they are used. The typical car battery, driven every day, properly charged, and never deep-cycled, could last upwards of 7 years, but thats a best-case scenario. Most maintenance-free car batteries tend to last 4 to 7 years. Short car battery life, less than 3 or 4 years, can be related to several different problems, such as lack of use, corrosion, excessive deep cycling, electrolyte evaporation, damage, or charging problems.
