Why Battery Replacement is Important

The battery is the heart of your electric bike, powering every ride. Using the correct battery model maintains optimal performance, battery health, and safety. Replacing an old or malfunctioning battery with an appropriate Magnum UL-certified Lithium-NMC battery ensures reliable range and power delivery.

Materials Needed

• Camera or smartphone to take a clear photo of the bike's serial number label.
• Access to the Magnum Bikes official website or authorized dealer portal.

• Basic tools for battery installation (e.g., screwdriver), if needed.

Step 1: Confirm Your Bike Model (Verify Voltage and Fit)

Locate the model name and serial number label on your Magnum e-bike. Typically, the serial number can be found on the frame on the headtube (front of bike) or on the chainstay. Take a clear photo showing the full serial number.

Next, send this photo to Magnum Bikes customer support ([e-mail]) or bring it to your nearest Magnum authorized dealer. Providing the serial number allows confirmation of the exact battery model originally equipped with your bike.  It will also help identify upgrade opportunities for greater range or performance. 

Step 2: Order the Correct Battery

Once the battery model is confirmed, you can order the appropriate replacement battery. Visit the Magnum Bikes official website at https://www.magnumbikes.com/ and navigate to the parts or accessories section to find compatible batteries.  If you have any doubts, our customer support team can verify compatability.

Step 3: Replace the Battery Safely

When your replacement battery arrives, carefully remove the old battery following these steps:

1. Use the key to unlock and remove the old battery from the frame mount, if needed.
2. Inspect the battery connector in the frame for charring, corrosion, or other damage.  If damage is present, stop and take a picture and send it to Magnum customer support to assess whether or not you need to replace a plug or wiring before moving forward. 
3. Once you verify that your battery connector is in good condition, verify the voltage and fit of the battery one last time, then install the new battery by connecting it securely to the bike's power system and locking it into place.
4. Power on the bike and verify battery status on the LCD display.

Always handle batteries with care and follow safety guidelines included with the replacement battery.
