VW Polo 9N Car Battery Replacement Removal and Installation.

Car battery removal and installation in VW Polo 9N AZQ Engine.
Follow the steps in the video precisely to avoid injury to yourself or damage to your car.

You can first try to recover and revive your dead car battery that was sitting a long time unused and the car won't start and the starter barely spins at all.

If the battery is revived but still doesn't have the amps power to start the car normally, you should replace the car battery or try again the desulfation pulse charger.

Even if the car battery starts the car but the starter is slower especially if the cranking seems slower especially in the cold mornings, it’s time for a new car battery.

The old battery in the video lasted 5 years and it’s time to replace it:
BOSCH S4002 470A (EN) 52Ah 12V
Ean Barcode: 4047023479389

New car battery details:
SpeedMate
55066 12V RC80 50Ah (20HR) 400 CCA(SAE)
Made in Korea

New car battery has a battery indicator with green for good, black for needs recharge and white needs to be replaced.

This is for this car but for your car it might be different if you have another engine.
This is for VW Polo 9N 1.2V 3 cylinder AZQ engine.

When replacing the battery, you can still use the old battery for projects that don't need the highest amperage instant delivery that a car needs or take it to a recycling center.
There are lots of people willing to take the old car battery from you.

What's important to watch for is how the dead car battery changes when put on the car battery charger.

If the car battery voltage is below the voltage limit for example at only 5V from 12V, you will need to use a special car battery revival charger also called a pulse charger to rejuvenate or desulfate the lead-acid car battery.

A regular charger will not charge a battery that was sitting a long time and reached a very low voltage but this can!
After bringing it to normal voltage 10v to 12V, you can continue the charge with your regular car charger.

If the battery charges from 0 to full within 10 minutes, the battery needs to be desulfated.

If the car battery takes hours to charge, it’s good and might be ok to drive but you have to see how the car starts the next morning.

This time the car was being driven every day but started noticing slower starter speeds when cranking the engine to start the car up.
If you drive your car regularly and notice it gets slower especially in colder weather, it’s better to be ready to either try a car battery desulphator pulse charger to make the battery last longer or replace the battery before you are stuck somewhere with the car not starting.

This battery lasted 5 years so it was pretty good and I didn’t want to have to keep charging it so I did replace it but I needed the car to start so charging it with the car battery charger made the battery work again until I had the new car battery ready to replace the old one.
