When Should You Change Your F150’s Battery

Posted: 11/18/2021


Q: When should you change the battery in a Ford F150?


When it comes to changing the battery of an F150 there are a number of factors that can come into play. Read on to learn when it's appropriate to change the battery in your truck, and what that all entails below.


There’s nothing more frustrating than hopping into the cab of your pickup early on a workday morning, turning the key, and listening to the motor crank and crank and crank without starting. That’s a big sign that it might be time to replace your battery, but it’s usually the last one, since that’s enough to get most folks to buy a new one. 


Even beyond a truck that simply won’t start, there are a few very reliable indicators of a battery nearing the end of its life.



Change Your F150 Battery If - Your Headlights Are Dim

If your car's battery is low, you will not be able to fully power the vehicle's electrical components, including the headlights. Insufficient headlight is not only dangerous, it also means that the car's battery is almost empty. This can also be seen in the rest of your car’s electric system. If it looks like you’re losing power, you probably are.


Change Your F150 Battery If - There’s Corrosion Around the Contacts

You should always be checking under the hood every once in a while just as a good vehicle owner. A great sign that your battery is on its last legs is too much corrosion build up around the contacts. It’s not a guarantee, though, so use it as an additional point of evidence if you suspect a battery issue.

In addition to these signs, there are other questions you might have about your Ford F150 battery. 

How long should a Ford F150 battery last?

The battery for any pickup truck, but especially a Ford F150, should last around 2-5 years. A big influence on how long those batteries last is ambient temperature. A battery that is hot for longer periods tends to last less time than a battery in cold temperatures. Hot weather can evaporate the liquid in the car's battery and damage its internal structure. Therefore, when estimating the battery life of a car, consider the climate in which you drive most of the time.

Does an Alternator Influence How Long a Ford F150 Battery Lasts?

Your Ford F150's battery life will be affected greatly by the quality of charging connections inside your vehicle. If the connection is not very good, the battery life will be greatly reduced. This is especially true in any truck or car with a heavy duty alternator. An alternator has the potential to easily damage your F150 battery if it is not well cared for. Make sure to inspect and maintain your alternator once every few months.
