Battery Backup Testing & Replacement
Battery Backup Systems
Many modern garage door openers include a battery backup system that allows the door to operate during power outages. This is required by law in some jurisdictions (notably California since 2019) and is a valuable safety feature for all installations.
The backup battery is typically a 12-volt sealed lead-acid or lithium-ion battery housed inside or attached to the opener power head. When AC power fails, the opener automatically switches to battery power and can typically operate the door 10 to 20 times before the battery is depleted.
Testing the Battery Backup
During maintenance, test the battery backup system:
Battery Replacement
Replace backup batteries every 2 to 3 years or when the opener's battery status indicator shows a low charge. Use only the manufacturer-specified battery type and capacity. After replacement, verify the charging circuit is functioning by checking the charge indicator LED.
California Battery Backup Law
Since July 1, 2019, California law (SB-969) requires all new residential garage door openers sold or installed in the state to include a battery backup. This is a common exam topic for technicians working in or supplying to California markets.
Test battery backup by disconnecting AC power and operating the door on battery. Replace batteries every 2 to 3 years or when the charge indicator shows low. California requires battery backup on all new residential openers since July 2019.
