A car battery is designed to last around two to five years, but it can die prematurely due to a number of reasons.
The main factors that lead to this happening include improper maintenance and corrosion from connecting cables or posts into the engine bay- which could have been avoided by taking care in parking spaces without extreme weather conditions like the hot sun hitting an exposed post all day long for example!
So do I need to replace my car’s battery after the jump start?
It’s a good idea in most cases because batteries do die at roughly five year intervals, and jump starting a battery can do more damage to it in some cases when compared to not jumping the battery at all.
In addition, if you do plan on replacing your battery in the near future, doing so right after a jump start will make sure that the new battery is properly charged.
Why does Battery Slowly Lose its Charge?
Here’s what’s happening inside of your car before you ever even turn the key:
When you do start your car up by turning the key, the alternator sends power through your car’s electrical system; this includes powering up your radio or air conditioner, heating, or A/C units (on newer cars), as well as providing power for things like headlights and taillights.
Once electricity makes its way into one end of your vehicle (be it a headlight, radio dial, A/C unit, etc.), it is being used up.
This is why over time, your car’s battery will slowly lose its charge or power as you drive around town and use up the little bit of juice that the alternator generates for you.
The reason this is important to do after a jump start is that when the car’s electrical system is fully charged with electricity from another vehicle, there can be some damage done during that process.
What is a Jump Start?
Jump-starting a dead battery basically means you’re connecting two batteries together through jumper cables; one battery will send its electrons into another battery if both sets of cables are attached correctly and in the right sequence.
When this happens near enough to each other (in a short amount of time), the batteries will do what it is they do, generating electricity and giving power to your electrical system.
This can cause a bit of damage if done incorrectly because if you do not do it correctly, there will be an electrical overload that could damage your car’s alternator or other parts that depend on the battery for power.
If this happens during a jump start, those damages may have already occurred as soon as you turned the key and started the car up again after jump starting.
That means if you do need to replace any part of your car’s electrical system, it makes sense to do so directly following a jump start.
It should also be noted that many people recommend always replacing cables whenever you hook up.
