A failing battery can manifest in various ways, causing frustration and potential safety hazards.

In the worst-case scenario, a completely dead battery will leave your garage door inoperable, making it difficult to enter or exit your home.

Regularly check the battery terminals for corrosion and clean them if necessary. You can also manually test the battery by disconnecting it from the opener and using a multimeter to measure its voltage. If the voltage drops below 12 volts, it's time to replace the battery.
