Setup and Installation

Before beginning installation, ensure the garage door opener is disconnected from its main power source to prevent electrical shock.

1. Locate the Battery Compartment: On your Chamberlain, LiftMaster, or Craftsman garage door opener, identify the battery backup compartment. This is typically located on the side or rear of the main opener unit.
2. Open the Compartment: Use a Phillips head screwdriver to remove any screws securing the battery compartment cover. Carefully open or remove the cover.
3. Disconnect Old Battery: Gently pull out the old battery. Disconnect the positive (+) and negative (-) terminals by carefully pulling the connectors off the battery posts. Note their orientation for the new battery.
4. Insert New Battery: Place the new Chamberlain 4228 Replacement Battery into the compartment. Ensure it fits snugly.
5. Connect New Battery: Connect the positive (+) wire (usually red) to the positive (+) terminal on the new battery, and the negative (-) wire (usually black) to the negative (-) terminal. Ensure connections are secure.
6. Secure Compartment: Replace the battery compartment cover and secure it with the screws removed earlier.
7. Restore Power: Reconnect your garage door opener to its main power source. The opener will typically begin charging the new battery automatically.
8. Initial Charge: Allow the battery to charge for at least 24 hours before relying on it for full backup power.

Operating Instructions

Once installed and charged, the Chamberlain 4228 Replacement Battery operates automatically with your compatible garage door opener.

• Automatic Charging: The garage door opener continuously charges the battery when connected to main power, ensuring it is ready for use.
• Power Outage Operation: In the event of a power outage, the garage door opener will automatically switch to battery power. You can then operate your garage door using your remote control or wall console as usual.
• Cycle Capacity: The battery is designed to provide power for approximately 20 cycles (open and close operations) during a power outage, depending on the opener model and door weight.
• Low Battery Indication: Your garage door opener may provide an audible beep or visual indicator (e.g., flashing light) when the battery charge is low or if the battery needs replacement.

Maintenance

Proper maintenance can extend the life of your replacement battery.

• Regular Testing: Periodically test your battery backup system by unplugging the garage door opener from the main power source. Operate the door a few times to ensure the battery is functioning correctly. Reconnect main power after testing.
• Terminal Inspection: Annually inspect the battery terminals for any signs of corrosion. If corrosion is present, disconnect the battery and carefully clean the terminals with a wire brush or a mixture of baking soda and water. Ensure terminals are dry before reconnecting.
• Environmental Conditions: Store and operate the battery within recommended temperature ranges (typically 32°F to 104°F or 0°C to 40°C) to maximize its lifespan. Avoid extreme heat or cold.
• Replacement: Batteries typically last 3-5 years depending on usage and environmental factors. Replace the battery when it no longer holds a charge or provides sufficient power during outages.
