When to replace your Car’s Battery

A car’s battery provides power for the vehicle during engine startup. To start an engine, its internal parts must be given an initial spin by the starter—a powerful motor—that draws power from the battery. If the battery fails to deliver the required power, the engine will not start. A workaround to provide the initial spin is to push the vehicle (for vehicles with manual transmission). To avoid the awkward moment of having to push-start your vehicle, the condition of the battery must be monitored, and if found to be defective, replaced as necessary.

Here are some indicators that your car’s battery needs replacement:

1. The battery is getting old. Batteries have limited shelf life. They are usually designed to last only up to 2-3 years. A battery that has gone beyond its warranty period may not hold enough charge to reliably start a car. The warranty period is usually indicated in the battery, as in the case of the stock battery of a 2017 EcoSport.

2. Errors are reported during engine startup. Errors may show up during engine startup if the battery can no longer supply the proper voltage to run the instruments. This usually happens when an old battery has been left to discharge for long periods, like parking the car overnight. Note that a battery discharges even when the car is not in use. In the case of an EcoSport, the error (ABS) Malfunction usually shows up when the battery voltage drops to a certain threshold, indicating the need for replacement. Errors may also show up while driving, as soon as you switch on the hi-beams.

3. Engine fails to start. The most definitive indicator of a battery that needs replacement is a failure during engine startup. This simply means that the battery can no longer hold enough charge to turn the starter and spin the engine. It may not be much of a problem for vehicles with manual transmission (MT) as one may resort to push-starting the vehicle, but for AT users, it is not an option. If the battery is relatively new (less than 2 years old) and a failure occurs, it may be caused by a discharged (drained) battery. A discharged battery may be recharged and replacement is not needed.

Have the battery checked each time you bring your car for servicing. As a general rule, replace your battery every 2 years.

  1. I had a lot of confusions regarding to car batteries and I cannot find solutions to these problems but after reading this article my problems are easier to solve. Thanks for posting such relevant stuff.


  2. My Ecosports 2014. Do not like to start. It just click if the key is turned butno sounds like “tsug tsug tsug grrr”.

    I tried jumper aftee 15 mins while my monty is on with revolution the same it doesnt like to ignite.


  3. My Ecosport’s (2017) battery went flat after 28 months.. I tried jumpstarting it to no avail, I know replacement is overdue. What bothers me is a notification saying transmission ” Is not on P”, although the lever is actually on Park. Is this due to computer error due to the flat battery?


    • It is most probably related to battery, but we cannot be certain until we have ruled out battery as a problem. It could also be a switch problem, or an actuator problem. Good luck!


    • I am not familiar with the SM equivalent, but the batteries that fit with the battery cradle are size DIN44 (the stock size) or DIN55 (next larger size that fits also). I used EmTrac and it seems to be working OK, but any automotive battery should work as well, for as long as you can fit it inside the battery cradle.
