Battery and Charger

1. Use only the SRAM-supplied charger and cords. Use of other chargers and cords may cause the battery to overheat, catch fire, and/or explode.

2. Replace rechargeable batteries with genuine SRAM rechargeable batteries only.

3. Replace batteries only with the type described in the user manual.

4. Used batteries are hazardous and must be recycled in accordance with the applicable local, federal, and/or EU regulations. Never dispose of batteries in a fire.

5. Do not use the battery outside of the temperature range specified in the user manual; avoid exposure to excessive heat or cold. Do not leave the battery in direct sunlight or in a vehicle.

6. Do not place the battery or charger in or near fire or in a place where static electricity occurs.

7. Do not modify or disassemble the battery or charger. Avoid dropping your battery or charger. Do not use a battery or charger that has been dropped or is damaged. Signs of damage include: discoloration, dents, cracks, punctures, or leakage.

8. Do not charge the battery in a damp or wet location. Avoid exposure to moisture and/or water during charging. For parts with a plug, do not insert or remove the plug while it is wet; otherwise, it may cause an electric shock. Make sure the plug is dry before inserting it.

9. Do not leave the battery in a charger or on equipment if it generates an odor and/or heat, changes color and/or shape, leaks electrolyte, or causes any other abnormality. If you notice any abnormalities, immediately remove the battery from the charger or equipment.

10. Do not leave a charging battery unattended. Do not leave the battery connected to the charger after charging is complete. Store the battery at room temperature with the battery cover on, if provided.

11. Do not allow metal, such as paper clips, coins, or keys, to come into contact with the battery terminals. Metal can damage the battery terminals and cause the battery to short-circuit.

12. This product may contain a coin/button cell battery, which is non-rechargeable.

13. If the battery compartment does not close securely, stop using the product and keep it away from children.

Press and release the Power button on the display to show the charge status when the battery is charging. At 100% charge, the battery will power off. Unplug the charger from the charge port and press the Power button on the display to power on the E-Bike.

The charge status is shown on the battery. The visibility of the status indicator may vary based on the integration of the battery into the E-Bike frame.

The current state of charge for the Eagle Powertrain Battery plus an Eagle Powertrain Range Extender will display the total system State of Charge (SOC) as a percentage above 100%.

The total system SOC will vary depending on the size of the Eagle Powertrain Battery, 630Wh or 720Wh. See the Battery Charge Status section for Powertrain battery charge levels.

Unplug the charging cord from the battery or frame charge port when fully charged. Install plug cover, if applicable.

1. Insert the battery into the frame with the charging port side of the battery into the frame plug bracket so the prongs are aligned (1a). Push up on the battery until the battery is secure (1b).

2. Install and tighten the bolt into the battery mounting hole in the frame while you push the battery into the plug side mounting bracket. Make sure the battery is connected to the plug. Firmly push the plug side mounting system as you tighten the bolt.
