How to Remove the Battery from a Buick Rendezvousby Johnathan Cronk
The Rendezvous is a mid-sized crossover SUV designed and manufactured by Buick. The battery within the vehicle is crucial to the vehicle running properly as it powers the lights, radio, ignition and other components. When the battery dies, the ignition will not start the engine, causing the vehicle to not start. Removing the battery in the Rendezvous is more difficult, as it requires you to remove a support bar that rests directly over the battery.
Place the Rendezvous in "Park" and turn all components such as lights and radio off. Remove the key from the ignition. Allow the vehicle to cool for a half hour.
Open the hood of the Buick. Locate the battery; the battery is found on the passenger side of the vehicle near the fuse box.
Remove the support bar that is blocking access to the battery. Remove the 13mm bolt behind the fuse box, using an extended socket. The secure bar can now be moved out of the way.
Remove the negative (black) battery cable using an 8mm socket or a 5/16 wrench. Twist and pull the cable off of the battery. Do the same for the positive (red) battery cable.
Remove the battery bolt. This bolt secures the battery in place and prevents unnecessary movement. Use a 13mm socket to loosen and remove the bolt. The battery can now be removed.
Lift the battery by the handle, straight out of the Rendezvous. The battery is in a tight spot; lift straight up with force.
