How to replace a car battery?

The following is a description of a car battery replacement. Its a fairly simple procedure and could be a “DIY job” for your car.

The battery getting installed into this 2012 Ford Figo is made by Amaron. It’s clear from the battery that the power rating is 45Ah (which matches Ford Figo requirement) and the manufacturing date is not more than 6 months

 

 

First, the old battery is removed from the battery bay by first disconnecting the negative terminal, and then the positive terminal.

 

 

Since the battery for this particular car hadn’t been changed in 4 years, terminal connectors had deposits on them. These deposits are cleaned away with the help of sandpaper.

 

The new battery is placed inside the battery bay and the terminals are connected. The positive terminal is connected first and then the negative terminal is connected.

 

 

A bit of battery terminal gel is applied on the terminals to prevent further accumulation of corrosive material

 

 

The new battery is then tested. It’s always good to take precautionary measures as manufacturing defects in such components are possible.

The multimeter is connected to the battery. You’ll see that the voltage value is around 12V. If the battery is good, at the time of cranking, the voltage will dip but not past 10V and it will rise back up and stabilize at around 14V. If the voltage dips past 10V then it means the battery is weak.
