Replace Battery by Yourself

Automotivers - Never underestimate the battery replacement. It may looks so simple, just relieving the bind on both battery polar by loosening the bolt. It is possible, error or carelessness happens when performing the replacement. Which could damaging the electrical systems and even electronic control unit (ECU).


Follow these steps to replace the battery.
1. Make sure the ignition key is in "OFF" positioned or uprooted. After that, let it for a moment to ensure electrical components really dead. To make sure the ECU is not active in order to avoid hangs or damage to the ECU. If the ignition is "ON", there is still an electric current and when the battery cable is revoked may potentially cause a spark.

2. To be safe, disconnect the negative cable first, and then the positive. This is to prevent sparks. When installing the cable again (after a new battery replacement), do the opposite. So, first connect the plus cable then the negative.


3. When installing a new battery, make sure the size and capacity is the same with the standard. Then pay attention to the position of poles. Trivial, but potentially damaging electrical components and the ECU if you put them wrong.

4. Some cars need to reset their ECU after replacing the battery. Especially for European-made cars.

5. Replace the battery as soon as possible when its conditions can not be helped. Like its cell had been burned or fused.
