Frequently Asked Questions
How long does a charge last in a smoke detector?
In low-power smoke detectors, a charge can last 3-6 months, depending on the frequency of the device's self-test and its age.
Can I charge the battery with my phone charger?
No, you need a dedicated charger for Ni-MH 9V batteries. USB phone chargers are not compatible and can damage the battery.
