Q: How do you remove and install Car Batteries on Nissan Altima?
A: To avoid programming again of some vehicle systems, it is best to install a memory saver device. Firstly, disconnect the negative cable from the battery and then follow by removing the positive Battery Cable. Notably, locate the battery hold-down clamp that straddles across the top section of the battery. Get rid of the bolts and hold-down clamp. Carefully take out the battery away from its compartment. Some auto parts stores stock special straps with which batteries can be lifted after being attached to their terminals; this seems to make lifting and transporting much easier. Consequently, reverse of removal will now take place during installation. However, the positive cable should be connected before the negative one. Lastly, perform required re-learn procedures.
