An opener backup battery is selected for the motor unit, not the handheld remote.
The detail that controls fit
The present catalog has no exact backup-battery fit records. Compare the original opener model and replacement part in its manual before purchase.
A practical next step
Write down the full opener or accessory model number from its label. Use the linked manufacturer documentation to match the exact replacement part. If a safety part or wiring is involved, bring that information to a trained technician.
Evidence status
Only the facts identified above are supported by the current source set. Missing model-to-part pairs remain unknown.
Which battery are you replacing?
The small cell inside a remote and the larger backup battery in the opener serve different jobs. The present data verifies several transmitter coin cells but no opener backup battery pairs. Find the full motor-unit model and any replacement battery number printed in its manual. If the battery compartment is damaged or the opener reports an electrical fault, follow the maker’s service guidance rather than substituting a similar-looking pack.
