What to do if my Kidde K5CO indicates a low battery?
- MMrs. Vanessa FitzgeraldJul 29, 2025
If your Kidde Security System indicates a low battery, push the test button once to silence the alarm for 24 hours. Note that 30 days after the low battery indication begins, replace the batteries as soon as possible.
