Also known as a boost, this quick-fix method starts a vehicle with a discharged/dead battery by connecting with another cars battery or another power source through jump leads.

Jump starts can sometimes be necessary if youre out and about on the road and need to get moving quickly. However, a better alternative for long-term battery maintenance is using a designated battery charger/maintainer while regularly testing your cars wattage between charges.

Its important that you know how to jump-start your car if you ever come to your car and its got a flat battery. Its also just as important to know what to do when you want to recharge your battery.

Heres a simple step-by-step guide to jump-starting and charging your car battery.

Maintaining A Car Battery

Aside from making sure the battery maintains a good level of charge, primarily by not leaving the headlights on overnight, most automotive batteries require regular maintenance in the form of checking the electrolyte level and specific gravity.

The electrolyte, which is a solution of sulfuric acid and water, should always cover the lead plates in each cell, since exposing the plates to the air can cause issues over time.

If the specific gravity is low across all the cells, the battery is typically in need of a charge. If the specific gravity remains low after charging the battery, that’s usually a good indicator that the battery should be replaced. If the specific gravity is only low in one cell, that indicates an internal fault, in which case charging the battery may actually be dangerous.

Although a vehicles alternator is capable of keeping its battery charged under normal circumstances, batteries do go dead for a variety of reasons, and there also comes a time in the life of every car battery when its just time to move on.

What Can Cause A Battery To Stop Charging

One of the most common reasons the battery light comes on and the car battery stops charging is because of corrosion. Whether the corrosion is on the battery cables or cable terminals, it is still a problem that needs to be addressed.

Another common culprit for the battery not charging is a problem with the alternator. The alternator powers the battery, and if it is not functioning properly the battery will not be either. This can be a problem with the actual alternator or the belt that drives it.

Another common cause of parasitic drain is when the car is left in a hot environment, such as a stuffy garage. The heat can cause the battery to overheat and discharge, even if the car isnât running.

A less common but possible cause of parasitic drain is a faulty alternator or voltage regulator. If either of these components is not working properly, it can cause the battery to discharge even when the car is not running.

Start by removing the liquid from the battery and rinsing it off with tap water. Get as much of the contaminants out as you can to prevent the bridging of the plates. Allow them to drain and dry once completely rinsed.

Mix the Epsom salt-water solution with the electrolyte of the battery Epsom salt. Add the mixture to each cell of the battery using a bulb-type filler or a dropper, whatever is available. Do not put the caps back on.

Finally, put the battery on the charger and leave it for a while, almost 7-8 hours. It will not only revive the battery but will recharge it as well confirming if the whole thing worked for the battery or not. Here is a charger you can use. It works pretty well for almost all batteries.

Does Using Heating Drain Your Car Battery

In the cold temperatures of winter, you might be urged to turn on your car heater while driving.

However, you must be wary of how this can affect your car battery.

The heater itself does not drain the battery because the heat is made up of the energy emitted by the motor.

However, for the heat to circulate around the car, there are fans installed which do drain up your car battery.

The fans get their power through the connection made to the ignition switch, and if the car is off, then there is no power going through to them.

That is why the fans should not be turned on without the engine running because they can drain your car battery.

What Are The Most Common Signs That My Battery Is Dying

When your car battery wont hold a charge, there are usually telltale signs that it’s dying. Some of the most common signs that a battery is dying are:

Check Engine Light Is On

Of course, when the Check Engine light illuminates this can mean anything but it also could signal that your battery is dying.

Engine Is Slow To Turn Over

Has it been taking a few extra seconds for your engine to fully turn over? A slow-starting engine is typically the last cry for help before your battery officially kicks the bucket. Eventually, the battery components become completely worn rendering them useless and ineffective. As a result, the battery will take a little bit more time to create a charge for the starter and the engine will slowly turn over.

Condition of the Battery

Is your car battery corroded? Another major common sign of a terminal battery is visible corrosion. This acidic, powdery blue material has a harmful effect on your battery. If the terminals are corroded it will interrupt and sometimes block the flow of electricity to the battery. In some cases, you may be able to thoroughly clean the acidic substance off of the battery and its terminals. Corroded positive and negative terminals can cause voltage issues and youll have trouble starting your car. After a while, this substance hardens and it depletes the battery of all its power.
