Depending on the model and brand of your garage door or gate opener, you may need to purchase a specific battery backup. However, there are a few general rules that can make your life easy when finding the right type:
If you have a MYQ Merlin opener, you will need the Merlin M-BBU24V.
If using a EVO Merlin opener, you will need the Merlin E475M.
If you have an ATA or B&D Gen1 garage opener, you will need the Gen1 battery backup.
Following the same logic, if you have a Gen2 opener you would need the Gen2 battery kit.
Please make sure to read the listing descriptions to ensure the kit is the correct one for your opener! If you need assistance, you can always contact us.
