Video tutorial

In this video we can see how to change the battery of the Volkswagen Polo IV: we open the hood, and we see the battery on the right side of the engine. We always start by disconnecting the negative terminal first, which is the black one; then the positive one. Using a 13mm key with an extension, we unscrew the battery support plate, then with a flathead screwdriver, we lever the fixing tab, then detach the entire unit from the box and lift it. We remove the battery.

We scrape the terminals with sandpaper to remove the oxide layer. We grease the terminals of the new battery with copper grease and install it in its place.

We reconnect the positive terminal, then the negative one and secure it with the support plate and the fixing cage. Operation completed.
