Jumpstarting a vehicle is an instant way to boost your dead battery. Usually, it is done with a portable jump booster. Jump boosters transfer a current from a live battery to a dead battery. It helps the alternator to charge the battery. But after that, the question arises: how long does the battery last after jump-starting?
Factors that Affect Post Jump Start Time
Let's delve into the factors that affect the post-time jump start time.
Battery Health
One of the most essential factors is the battery. If the battery is new, then it will be fully charged after 20 minutes of driving. If the battery is old —like 3 to 5 years old —it takes the alternator longer to charge it because of its age.
Weather Condition
Weather is another factor that plays a vital role in determining the time after a car jumpstart. In cold weather, the chemical reaction inside the battery is slow, and it tends to discharge more quickly. It takes longer to charge in cold weather than in hot weather.
Faulty Alternator
If the alternator is not in good condition, even after a jump start, the car battery dies suddenly because the alternator is not providing enough charge. The alternator charging problem quickly drains the battery.
Battery Size and Capacity
Post-battery time also depends on the battery's size and capacity. Usually, big car engines with large batteries take longer for the alternator to charge than smaller engines. The type of vehicles varies post-charging time.
Battery Terminal
Sometimes, the battery terminals are dirty, preventing the battery from holding a charge. It causes the battery to drain quickly.
Sign that Leads to Replace Battery
Below are the signs; if they appear, immediately get the battery tested and replaced.
- If the engine keeps making odd noises.
- Dashboard lights keep appearing.
- The battery dies even after jumpstart service.
- Dim or flickering lights.
- The car won't start even after the jump start.
Final Thoughts
Jumpstarting a vehicle is a good way to get back on the road quickly, as it's instant and straightforward. It is crucial to decide how long the battery lasts after a jump start. Considering the above factors helps you to determine the time.
