It's just not working.
There is a large difference from the duration of the Instruction Manual.
It doesn't make sense if it doesn't ring when the need arises.
Wiring directly to Battery is still better.
The 9V rectangular battery is also very difficult to attach and quite difficult to use with the box shape.

It is easy to install, but it is disappointing - - - -
When I purchased it last time I used it with BatteryWiring, but since it was described as using 180 to 250 hours, I tried to purchase it for real.
Results using 2 weeks.
9V battery Toshiba IMPULES rechargeable battery xQuantity : 2pc. Unfortunately we could not use 180 to 250 hours of description as described, but we could not use x 3 = 36 hours only during 12 hours of nighttime three days.
In the morning of the third day, since there is no sound of cancellation of alarm, it seems to be a discharge in the middle.
Toshiba IMPULES capacity is 200 mAh, standby current consumption : 4. Since it is described as 5 mA, 200 mAh / 4. Since 5 mA ≒ 44 h and working voltage 9 - 12 V, the voltage drops due to capacity reduction, so 44 h can not be used?
There is continuous use 180 to 250 hours - - - - -
(What kind of batteries would you like me to describe if the above use time is possible?)
Depending on Battery usage frequency, degradation state, capacity,
After all BatteryWiring is still recommended.
