How to Change the Battery in Honda Cars

by Contributing Writer; Updated June 12, 2017

The battery on the Honda car is on the driver's side toward the front of the engine compartment. The battery is secured to the engine compartment by a plastic mount on the back of the battery. The mount is held in place in the engine compartment by a single bolt and nut. The mount will slide off of the bolt once you have removed the nut from the top of the bolt. The nut can be removed by twisting it off with your hand.

Removal

Remove the key from the ignition. Install the memory saver per its manufacturer's instructions. Not using a memory saver can cause several problems. The stereo-navigation unit will lock and the clock will need to re reset. Make sure you have your radio lock code before you proceed without a memory saver.

Remove the negative battery cable and isolate it from the battery. Using the ratchet and a 10 mm socket, remove the two nuts holding the battery cross-bar in place. Remove the cross-bar. Using the same size socket, loosen the negative battery cable nut. Loosen the positive battery cable nut, remove the cable and isolate it from the battery.

Remove the battery cover from the battery by lifting it straight up. Remove the battery from the car without tilting it too much. You do not want to allow any acid to spill. Clean any corrosion from the battery cable ends with the wire brush.

Installation

Match the new battery to the old battery, making sure that the positive and negative terminals are on the correct side of the battery. Install the battery into the vehicle. Place the battery cover over the battery.

Install the positive battery cable and tighten the clamp nut to 4 foot-pounds. Install the battery cross-plate and tighten both hold-down nuts until they are snug and you cannot move the battery by hand. Install the negative battery cable and tighten the clamp nut to 4 foot-pounds.

Apply a light coat of dielectric grease to the battery terminals to prevent corrosion. Remove the memory saver. Start the car and verify that all electrical systems are working properly.

Removing the Old Battery

Pop the Pilot's hood and open it by sliding the latch under the hood from right to left.
