Dead Car Battery

Dead Car Battery: How to Fix

Dead Car BatteryAccording to the AAA, a dead car battery is the number one reason American motorists call for roadside assistance. If your car or truck won’t start, more often than not, the battery is dead. Dead car batteries are especially prevalent in the age of Covid social distancing. Where cars, trucks, and SUVs are driven less frequently, or not at all. Whether it’s due to drivers being out of work, working-from-home, schools. Businesses being closed or simply not having the money. People just aren’t driving as much as they used to. A decrease in overall driving activity increases the risk of a dead car battery. This is due to a reduction in the charging it receives from the engine’s alternator as a result of regular driving.

What to Do About A Dead Car Battery


The most common method drivers cope with a car or truck that won’t start due to a dead battery is a jump-start. Keeping a set of jumper cables in your trunk is always a good idea. If you do not have access to any, you may be able to flag down a fellow motorist. Make sure to use your best judgement and approach any individuals on the road with caution.

After popping open the hood of both vehicles, first connect the red positive clamps to the red positive terminals on both auto batteries. Then connect the black negative clamp to the black negative terminal on the vehicle with the fully functioning battery that will be doing the jumping. Next, attach the remaining black negative clamp to any paint-free metal part or surface within the engine block. After first starting the working vehicle and letting in run a minute or two, you will then attempt to start the vehicle with the dead car battery. If it starts, make sure to drive around for a recommended 30-minutes or more, to sufficiently charge the battery via the engine’s alternator.

If you consider yourself fairly handy, and have the necessary time and resources available, servicing or replacing your vehicle’s battery can be done as a do-it-yourself fix. First, you will need a multimeter, a handheld electronic device used for measuring electric current. After setting the multimeter to the 15 to 20-amp setting, connect the red positive and black negative contacts to the corresponding positive and negative terminals on the car battery. Did the reading registers below 12.5 amps? You will want to either charge or replace your battery depending on its overall condition and lifespan.

While your vehicle’s alternator maintains your car or truck’s battery charge through regular driving, it was never designed to fully charge the battery; for that, you will need a dedicated car battery charger. If you’ve properly charged your vehicle’s battery and it is still experiencing power loss or failure to start, then it will need to be replaced. The easiest way to figure out which battery to buy is by referencing your vehicle’s owner manual, or simply popping open the hood and taking a look. It is essential you choose the correct size and power rating. The main units of measurement when it comes to rating an automotive battery is Cranking Amps (CA), the amount of electric amperage it takes to start a vehicle at 32-degrees Fahrenheit, along with Cold Cranking Amps (CCA), the amperage required to start an automobile at zero-degrees Fahrenheit.

As evidenced by the difficulty of starting a car in cold climates.

Old Age

The average car battery lasts roughly three to five years. Did you notice significant levels of corrosion? Leaking fluid, a foul sulfuric odor, or the battery is swollen or deformed, it is time to take action. Does your vehicle battery is experiencing any of these symptoms?
