Before installing the new battery, double-check its specifications to ensure it matches the old battery’s group size and CCA rating. Additionally, inspect the new battery for any signs of damage or defects.

5.2 Placing the New Battery

Follow these steps to place the new battery in your Subaru:

1. Carefully position the new battery in the battery tray, ensuring it is aligned correctly.
2. Make sure the positive and negative terminals are easily accessible.

5.3 Connecting the New Battery

To reconnect the new battery, follow these steps:

1. Start by attaching and tightening the positive terminal clamp onto the positive battery post using the appropriate-sized wrench or socket.
2. Repeat the process for the negative terminal clamp.
3. Ensure the terminals are securely connected with no loose connections.

Section 6: Securing the Battery

To ensure the new battery remains secure in your Subaru, follow these steps:

6.1 Reattaching the Battery Hold-Down Bracket (if applicable)

If your Subaru has a battery hold-down bracket, follow these steps to reattach it:

1. Position the battery hold-down bracket over the new battery.
2. Use the appropriate-sized wrench or socket to tighten the bolts or screws, securely fastening the bracket in place.
