What makes a car battery last so long?
There is no simple answer, but based on decades of industry experience, we know that three key factors affect the life of a car battery: time, heat and vibration. Batteries gradually deteriorate until they can no longer provide enough power to start an engine.
What happens if you let a car battery go dead?
Finally, allowing any car battery to go completely dead will take a big chunk out of its lifespan, even if it can be recharged and put back in service. You may have a battery problem if the starter motor cranks the engine slowly or the Battery/Charging warning lamp is illuminated.
What should the battery voltage be when the car is running?
The voltage, when the engine is running, should be in the range of 13.5-14.7 volts. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage. If you’re readings are significantly higher or lower than these then it would indicate a fault with the battery and/or the alternator.
Is it necessary to replace a car battery with a lower rating?
To avoid electrical system problems and a visit to the repair shop, never install a battery with a CCA or Ah rating that is lower than that recommended by the vehicle manufacturer. A higher-rated battery will also work if it fits properly, but is usually unnecessary and may have a shorter service life in hot climates.
How long does it take for car batteries to wear out?
This wear time could take three to five years and a vehicle’s usage pattern is one factor contributing to the rate at which a battery will age. Batteries in cars driven mostly on short trips may not fully recharge and batteries in vehicles parked for extended periods naturally self-discharge.
How can I tell if my car battery is good?
If you don’t have a battery tester, you can still see if the battery is good by jump-starting the car. Drive or run your car for about an hour or so, turn it off, and then restart it. If it starts, the battery is good. If it doesn’t and you need to jumpstart it again, drive it to the nearest automotive store and buy a new battery.
When do you need a new car battery?
A higher-rated battery will work if it fits properly, but is usually unnecessary and may have a shorter service life in hot climates. When your car needs a new battery, always purchase one from a high-volume seller with fresh stock. You do not want a battery that has already lost a good portion of its service life sitting on a shelf.
Can a car battery be one size fits all?
Car batteries are not one-size-fits-all You must consider the battery type, physical size, terminal configuration, and cold cranking amps (CCA) or amp-hour (Ah) rating to ensure you get a car battery that properly fits and functions for your make and model vehicle.
