2. Disconnect the positive terminal (red cable) in the same manner.
3. Remove any securing brackets or bolts holding the battery in place.
4. Carefully lift the battery out of the tray (consider its weight).

3. Charge or Replace the Battery

If Charging:
1. Connect a smart battery charger to the battery terminals, ensuring correct polarity (positive to positive, negative to negative).
2. Set the charger to the appropriate setting for your battery type (usually 12V).
3. Allow the battery to charge fully, typically a few hours or overnight.
If Replacing:
1. Acquire a new battery that matches the specifications for your Toyota Corolla E210 (usually Group Size 24F).
2. Place the new battery in the battery tray and secure it using the brackets.

4. Reconnect the Battery

Tools Required: Socket set.
Sub-steps:
1. Connect the positive terminal first, ensuring a tight fit.
2. Follow with the negative terminal.
3. Ensure that there are no tools left in the engine bay before closing the hood.

5. Test the Installation

Turn on the vehicle to ensure all electrical systems are operational.
Check for any warning lights on the dashboard.
