Ajax KeyPad: original replacement battery
The right batteries for your KeyPad (control panel). The same AAA type that Ajax supplies preinstalled, so you keep the specified service life and reliability.
Fit them again within a few minutes: battery cover open, old cells out, new ones in, cover closed. The hub and the Ajax app report by themselves, well in advance, that the battery is almost empty.
