The typical cost of a car battery is somewhere between $50 and $120, according to

While this range covers the cost of the part itself, the bill is not finalized as there are additional labor costs that could be very significant.

In the automotive world, repair costs are divided into labor and parts costs. Parts costs are usually the same everywhere you get your car repaired. However, labor cost differs from the service location.

For instance, if you get your car repaired at a small repair shop, you will significantly lower the price than a dealership.

On the other hand, many people prefer to get their cars repaired at a dealership, especially luxury cars. This is because they trust that the dealership mechanics are experienced enough to repair the vehicle without causing other problems.

Lastly, when the repair is not very complicated, many people get it done on their own using available DIYs on the internet.

Corrosion Of The Battery Terminals

Corrosion around the positive terminal or negative terminal is a sign of an overcharged or leaking battery which significantly weakens battery power.

If you see a battery terminal covered in a bluish crystalline substance, battery acid has leaked out, causing corrosion at the battery terminal and its time to get your vehicle a new battery.

What Causes A Dead Car Battery

A dead car battery can come about because of a lot of different reasons, such as:

  • An electrical component stayed on when the engine was off
  • The car hasnt been used driven for a long time
  • The vehicles alternator isnt charging the battery
  • Corroded terminals reduce the charge the battery can receive
  • Low temperatures during cold weather might have frozen the battery
  • Very high temperatures in hot weathermight haveweakened the battery

Several automotive experts indicated that removing corrosion from the batterys wiring and terminals can expand the lifetime of the battery. You can do so using products made specifically to remove corrosion from the auto part store. If you dont want to spend a lot of money, you can use baking soda with some water and scrub the corroded places. Of course, you want to follow the safety steps to avoid getting into any injuries.

Find the Proper Ground Points

In rear-wheel drive cars, you might find that the factory ground strap goes off the transmission to the transmission or engine mounts.

In front-wheel drive cars, the ground strap usually goes from the transmission to the firewall or the original battery to the chassis ground point. In any case, its best to check your service manual to find the original mounting points.

Appropriate Gauge Wire

As with the negative battery cable, you need at least a 6-gauge wire to avoid melting and burning. But again, its best to check a service manual to make sure a thicker one is required.

Two Cable Lugs

In this case, you need two cable lugs since both ends are held down with boltsone side to the transmission and the other to the chassis.

Clean Mounting Points

And clean mounting points on both sides, the chassis and the engine or transmission. Otherwise, the wires might overheat, destroy your battery or other and more expensive electrical systems.

    Engine Is Hard To Start

    Just like when your engine cranks slowly, your battery may not be delivering the high amperage needed to the starter motor, making the engine hard to start.

    Diagnostics suggested:

    Inspect the battery terminals. Make sure they are clean and tight, and the cables are in good condition.

    Check the battery’s voltage with an open voltage test as described in section A above.

    Slow charge the battery, if necessary, or have the battery tested at your local auto parts store.

    The other major issue that is common in vehicle that wont start is the alternator. Signs of a bad alternator include starting issues , stereo output issues and dimming lights. If you can start your car with a jump, but your car stalls out while you are driving, it is probable that the alternator is not functioning properly and the battery is not being charged.

    Another sign to look out for is a squealing noise when you are using electronic components such as the heater or the radio. This symptom points to an issue with the alternator bearings.

    If the car wont start but the headlights and other electrical components are working then the problem is likely the starter or a fuel issue.

    Appropriate Gauge Wire

    Most cars use a 6-gauge negative wire, and its crucial to have one of that thickness, and its even better to check what your car uses from the factory because it could be thicker. A thin ground wire will increase current resistance and cause a lot of electronic gizmos.

    Cable Lug

    The best thing you can do is get a cable lug that holds the wire with bolts instead of pressing or soldering. That way, its easier to install, but also make sure you isolate everything except the end connection. I suggest shrinking tubes for that.

    A Clean Mounting Point

    Once you find the original ground point, make sure to thoroughly clean it with a wire brush and contact cleaner spray. Since the ground point is exposed to weather, its absolutely crucial to clean it in order to make a good connection.

    Poor Performance In Cold Weather

    In general, car batteries do not perform well in the cold. Drivers that live in regions that see snow or other cold weather conditions must be especially mindful of their car battery health during the winter. If it gets cold enough, your battery can actually freeze. Its chemical reactions will start to slow down. Maximum current is demanded from the car battery in cold weather due to slow-moving engine oil. This will quickly drain the life out of a battery as it requires much more power to start the engine. During the winter, if you begin to notice poor performance from your vehicle when starting, your battery may be weakening. According to Jeff Barron of Interstate Batteries Lab, If its going to get cold, you want to get it checked. Drive it to a shop and get it checked, just like you want to check your anti-freeze. Newer batteries can manage colder weather more efficiently, so it is a good rule of thumb to have your battery replaced by a mechanic ahead of the cold weather season.

    Alternative Starting And Battery Problems

    Are you experiencing starting issues after getting a battery replacement? Is your new battery dying prematurely? Are you having a hard time safely jump-starting your car? These are signs that your issue exists beyond a dead battery:

    • Alternator Issues: Your cars alternator is responsible for recharging your battery while you drive. If your battery dies soon after the replacement, you could have an alternator issue.
    • Bad Battery: Alternatively, a battery that dies soon after replacement could be a sign of a faulty battery. While this is rare, it is not unheard of. Thankfully, you will likely be covered by a warranty if you visit an expert mechanic.
    • Drained Battery: Are you keeping your battery protected? Leaving lights on or chargers plugged in could be killing your car battery.
    • Starter Problems: As the name suggests, your cars starter is responsible for starting your vehicle. If there is an issue with your starter, your vehicle will not crank up, even with a full battery.

    Starting tests and vehicle diagnostics can be completed to detect the source of your vehicle issue. A mechanic will then work with you to develop a repair plan that will get your car working again.
