- 12V Lithium-Ion Batteries: Newer models often use rechargeable lithium-ion batteries. These are more efficient, compact, and environmentally friendly.
- Nickel-Cadmium (NiCd) Batteries: Some Craftsman garage door openers use rechargeable NiCd batteries, which are reliable but may suffer from the “memory effect” if not properly maintained.
Make sure to consult your user manual or the battery compartment label for specifics on the type of battery needed for your particular model.

How to Change Battery on Craftsman Garage Door Opener: Step-by-Step Instructions
Follow these simple steps to change the battery on your Craftsman garage door opener:
Step 1: Unplug the Garage Door Opener
The first step in how to change battery on Craftsman garage door opener is to ensure the opener is disconnected from power. Always unplug the garage door opener from the electrical outlet before you begin any work. This is a safety precaution to prevent electrical shock or damage to the unit.
Step 2: Locate the Battery Compartment
Once the opener is unplugged, find the battery compartment. On most Craftsman models, the battery compartment is located on the back of the opener motor unit. You may need to remove a cover or panel to access it.
Step 3: Remove the Old Battery
Next, carefully remove the old battery. Depending on your model, the battery may be secured with screws or clips. Use a screwdriver to remove any screws that are holding the battery in place. After removing the screws, gently pull the battery out of the compartment.
If the battery is connected with wires, make a note of which terminal each wire is attached to. The positive terminal (usually marked with a “+” symbol) and the negative terminal (marked with a “-“) must be connected correctly to avoid damaging the new battery.
Step 4: Install the New Battery
Take your new replacement battery and carefully place it in the battery compartment, aligning the terminals with the corresponding wires. If you’re replacing a 12V battery, make sure you’re using the same voltage rating to avoid damaging the opener.
- Positive Terminal First: Attach the positive terminal (red wire) to the positive side of the battery.
- Negative Terminal Second: Attach the negative terminal (black wire) to the negative side of the battery.
Secure the battery by reattaching any screws or clips that were holding it in place.
Step 5: Reassemble the Opener
Once the new battery is installed, it’s time to reassemble the opener. Close the battery compartment and secure it with any screws or fasteners that were used previously. Make sure everything is tightly in place and there are no loose parts.
Step 6: Plug the Opener Back In
Now that the new battery is installed, plug the garage door opener back into the electrical outlet. Turn on the opener and listen for any sounds indicating that it’s working. You should see an indicator light showing that the new battery is functioning properly.
Step 7: Test the Garage Door Opener
The final step in how to change battery on Craftsman garage door opener is to test it out. Use your remote control or the wall-mounted button to open and close the garage door. If everything is working smoothly, your replacement battery has been successfully installed.
