Smart smoke detector

rolf

I have 10 smoke detectors, all of which were manufactured in February 2019. Replacement date: February 2029. The batteries in two of the devices have already failed. That's four years too early! Unfortunately, it is not possible to replace the batteries. Will these devices be replaced?
Thank you for your feedback.
Kind regards,
Rolf Vaqué
