Step-by-Step Guide to Replace Hero Passion Pro Battery

Step 1: Turn Off the Engine

Ensure the bike is turned off completely and remove the key. For safety, you can also remove the ignition fuse.

Step 2: Locate the Battery Compartment

The battery in the Hero Passion Pro is located under the left side panel. Use your hand/ screwdriver to remove the side cover carefully.

Most panels are held by clips or screws. Check your model before pulling.

Step 3: Disconnect the Old Battery

Once the battery is visible:-

• Always disconnect the negative terminal (-) first to prevent any short circuit.
• Then, remove the positive terminal (+).
• Unscrew or unclip the battery holder/strap. Gently take out the old battery.

Step 4: Clean the Terminals

Use a dry cloth to clean the battery holder area and terminal ends. You can gently scrub in case of any rust or corrosion on the terminal. Do not use water.

Step 5: Install the New Battery

• Place the new battery in the holder carefully.
• Secure it with the battery strap/ clips.
• Connect the positive terminal (+) first, then the negative terminal (-).

Tighten both connections properly, but avoid over-tightening.

Optional: Apply a small amount of petroleum jelly or battery terminal grease on the connectors to prevent rusting.

Step 6: Replace the Side Panel

Once the battery is fixed and connections are tight, place the side cover back into its position. Ensure all clips/screws are properly aligned.

Step 7: Test the Bike

• Turn the ignition key.
• Check if the dashboard lights up.
• Start the engine—if it starts quickly, you're all set.

Check the horn, indicators, and headlight. If everything works smoothly, the battery replacement is successful!

Safety Tips

• Never connect the positive terminal first when removing the old battery.
• Avoid touching battery acid.
• Dispose of the old battery properly.

Don’t touch the terminals with your bare hands.

• Start your bike often, even if you do not ride it every day.
• Don’t leave the lights or indicators on when the engine is off.
• Try to park in the shade so the battery doesn’t get too hot.
