How To Keep Car Battery From Dying
In most cases, by only avoiding parasitic drains on the battery and keeping the car from extreme temperatures will keep your car battery from dying. Also, it would be best if you considered charging the car battery fully, not using any unnecessary car accessories, and keeping the car battery clean to stop the car battery from dying.
Here are some tips to keep car battery from dying:
- Charge Car Battery Regularly
- Aware of Parasitic Drain
- Keep The Battery Clean
- Avoid Driving Short Distances
- Keep Car Battery In Normal Temperatures
- Do Not Use Unnecessary Car Accessories
- Choose The Right Battery
- Charge The Car Battery Using A Trickle Charger

1. Charge Car Battery Regularly
Automobile batteries need to charge regularly and properly to mobilize a vehicle’s electrical system.
From engine cranking to headlights on, vehicles need battery charge to do all of them.
A car battery can charge in two different ways. The car battery can recharge by an alternator and also with an external charger.
An alternator is only going to recharge the battery when the car is running. So, by driving your car battery regularly, you can charge your car battery which keeps your car battery from dying.
But, recharging your car battery from an external charger is always the best and most effective way to keep the car battery from dying.
Using your car battery charger, you should charge your car battery on a regular basis. When you read 12.4 to 12.8 volts, it means your car battery is fully charged.
A compatible car battery charger needs around 10 to 14 hours to charge your car battery fully. And a car battery should be charged every four or six weeks.
You better be aware, when your car sits for a long time, the battery starts losing the capacity to hold charge to operate. And eventually, the battery died completely.
You can charge your car battery in several ways. You can even charge your car battery without a charger. So charge your car battery regularly.
2. Aware of Parasitic Drain
Most of us car owners are already familiar with parasitic drain. The parasitic drain is also known as a parasitic draw.
Parasitic draw on your car battery means when your car’s electrical system continues to drain power or energy from the battery, even when your car is shut off completely.
Over time parasitic drain makes a car battery dead by consuming unnecessary charge from the battery.
To keep your car battery from going flat, you must be aware of the parasitic drain on your car battery.
Make sure you turn off every electrical component, such as the radio, the internal clock, power mirrors, interior lights, and exterior lights, before leaving your car.
Run parasitic drain tests in your car on a regular basis to ensure the car’s electrical components are not drawing unnecessary electricity.
If you haven’t performed a parasitic drain test on your car battery before, then you can contact your nearest auto repair shop.

3. Keep The Battery Clean
By following a variety of ways, you can clean your car battery in a little bit of time.
When the battery does not clean for a long time, car battery leaking acids and dirt make corrosion all over the battery, which is a major reason why your car battery keeps dying.
Dirt and corrosion on your car battery also cause dead cells in the car battery and makes the battery obsolete.
You also should not forget to clean the battery terminal because the battery terminal is responsible for supplying and receiving the energy.
A neat and clean battery terminal will help your car battery stay in good health and extend its lifespan.
Also, the car battery does not need to be cleaned too often, and cleaning the car battery is easy to work on compared to washing the car.
Ensure your car battery is clean if you want to keep the car battery from dying when not in use also.
4. Avoid Driving Short Distances
Sometimes it’s become necessary to drive a car short distances, but often short distance driving is harmful to car batteries.
Driving short distances is not only bad for your car battery, but it also can cause bad motor oil in the car.
But, for short-distance driving, the alternator affects the most, which is leading to your car battery dying.
The car battery gets recharged by the alternator. An alternator can only recharge the battery when the car runs at optimal speed.
So, when you are driving too short distances for lack of enough car running time and speed, the alternator won’t be able to recharge the battery.
If you constantly drive too short distances, the car battery will keep dying because the battery is not getting sufficient charge to operate the car’s electrical system.
To prevent your car battery from dying, you should avoid driving short distances.
Ensure you drive your car at least 10 or more miles at 30-40 mph speed to recharge the battery.

5. Keep Car Battery In Normal Temperatures
Too cold or hot are both equally capable of keeping your car battery dying in anywhere and every situation.
Vehicle owners often ignore parking their cars in suitable and normal temperatures.
The best car battery drain solution is packing or storing your car battery at normal or home temperature.
Avoid parking your car in extreme temperatures. At home, you should park your car in the garage.
If you are outside of your home, make sure you park your car away from the sun or extreme heat.
Storing your car battery at home temperature is necessary if you need to keep the car battery from dying when not in use.
6. Do Not Use Unnecessary Car Accessories
The car battery supplies energy to every electrical component in a car. So, as you can imagine, the battery has a crucial role in operating the whole vehicle.
Every electrical component drains a certain level of charge from the battery to function.
But, the car battery keeps dying when you use unnecessary car accessories that also draw energy from the battery.
Unnecessary car accessories like a starling headliner, popcorn maker, Drivemocion Car LED Sign, and more accessories are not necessary for your car.
These accessories always draw unnecessary battery charges and lead the car battery to recharge frequently.
Unplugging all unnecessary accessories from your car to save your car battery from going flat.
7. Choose The Right Battery
Before buying a battery for your car, make sure the battery is the right size and has the ideal capacity for your car’s electrical system.
In Particular, you must see the battery’s reserve capacity before buying a car battery.
Improper and wrong size of the battery cannot be able to operate the car’s electrical system in the right way.
Therefore, the battery gradually leads to dying and causes the car’s electrical difficulty.
Take guidance from an automobile battery professional before buying the battery for your car if needed.

8. Charge The Car Battery With A Trickle Charger
Like a typical car battery charger, a trickle charger is also a car battery used for charging the car battery.
A trickle charger’s main purpose is to charge the battery slowly and prevent overcharging the battery simultaneously.
Car batteries are made by lead-acid battery technology. That’s why charging the car battery slowly is better than charging quickly, which is what a trickle charger does.
Especially a trickle charger is very handy for storing car batteries, which keep your car battery from dying when not in use.
Although a trickle charger is not necessary for every driver, if you have the budget, you should invest in a trickle charger because this will keep your car battery healthy.
9. Check for Loose Cable Connection
As a mechanic, I couldn’t stress enough how important it is to check the car battery cable connection on a regular basis.
Every battery connection must be tightened and connected properly to the car’s functional electrical systems.
Although loose battery connections do not make a car battery dead, loose connections prevent the battery from being charged.
When the car battery isn’t recharged for loose connections, eventually, the battery is going to be drained completely.
Also, loose battery connections will prevent the car’s electrical system from operating properly.
Therefore, I recommend car owners check their car battery connections at least twice a year.
