Follow these steps carefully
Switch the engine off and open the trunk. Lift out the mat and look for the battery under its plastic panel or fabric trim cover. Jump-starting uses remote posts under the hood; don't confuse those with the real battery.
Use a plastic trim pop-rivet tool to release the fasteners holding the trunk-side trim around the battery — prying with a screwdriver cracks the clips. Set the trim and cargo mat aside where they won’t get stepped on.
I've learned: that photo-before-you-touch advice is the cheapest insurance on this job. Those feeder wires look obvious until you're staring at four loose ring terminals. One wrong landing and you're paying a dealer to sort out the electronics.
With a 10mm socket and ratchet, loosen the nut on the black negative cable clamp and slide it off the post. Tuck the cable toward the quarter panel so it can’t swing back onto the terminal.
Label each wire or photograph the layout before removing them. Fold the whole positive assembly back, clear of the battery.
Remove the hold-down hardware at the base of the battery: a wedge block or clamp bar secured by a bolt (13mm or 14mm depending on build).
I've found that the vent tube is non-negotiable on trunk batteries — hydrogen has to go outside, not into the cabin. And it must be an AGM replacement; a flooded battery in an enclosed trunk is a corrosion and gas problem waiting to happen.
Lift the old battery straight up and out — it’s heavy and the trunk opening gives you limited handholds, so get a helper if the angle feels awkward. Clean the tray of any corrosion with a wire brush and wipe it down. Lower the new vented AGM battery in with the same terminal orientation, reconnect the vent tube, and refit the hold-down so the battery can’t shift under hard cornering. A loose battery in a Camaro’s trunk becomes a projectile.
Refit the feeder wires to the positive terminal block exactly as photographed, snug the positive clamp until it won’t twist, then reconnect the negative cable last and re-seat the battery sensor connector.
I've learned never to skip the registration step on these cars. The charging system tailors itself to the battery's age — swap in a fresh battery without registering it and the computer keeps overcharging it like it's the old one.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
