I don't. My experience has been that a power failure of a day or so has not resulted in appreciable battery drain, in terms of lowered voltage once the power is back. > When there is no power failure, you still change them regularly (every 2 > years for example) I don't change them on a schedule. The console reports voltage, and when it drops below 4.50V (meaning 1.50V each, assuming even discharge), I will replace them. Mine are currently at 4.59V, which is probably 1.53V x 3. (To make this happen, I have set an alarm in Home Assistant which gets the battery voltage via mqtt.) -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
