Carefully place the new battery into the tray, ensuring it’s properly aligned. Replace the hold-down clamp and tighten the bolts securely.
7. Connect the Positive Terminal
Connect the positive (+) cable to the positive (+) terminal on the new battery. Tighten the nut securely.
8. Connect the Negative Terminal
Connect the negative (-) cable to the negative (-) terminal on the new battery. Tighten the nut securely. (See Also: Does Bluetooth Transmitter Drain Car Battery? Surprising Truth Revealed)
