Nissan Sentra/Pulsar/NX 1982-1996 Repair Guide



Refer to Routine Maintenance for details on battery maintenance.


  1. Disconnect the negative (ground) cable from the terminal and then the positive cable. Special pullers are available to remove the cable clamps. To avoid sparks, always disconnect the ground cable first and connect it last.
  3. Remove the battery hold-down clamp.
  5. Remove the battery, being careful not to spill the acid.

Spilled acid can be neutralized with a baking soda/water solution. If you somehow get acid into your eyes, flush it out with lots of water and get to a doctor.

  1. Clean the battery posts thoroughly before reinstalling or when installing a new battery.
  3. Clean the cable clamps, using a wire brush, both inside and out.
  5. Install the battery and the hold-down clamp or strap. Connect the positive, and then the negative cable. DO NOT hammer them in place.

The terminals should be coated lightly (externally) with petroleum jelly to prevent corrosion. Another corrosion inhibiting product is felt washers impregnated with an anti-corrosion substance; these washers, which are available in auto parts stores, are simply placed over the battery posts before installing the cables. Make absolutely certain that the battery is connected properly before you turn on the ignition switch. Reversed polarity can burn out your alternator and regulator within a matter of a split second.
