Question about Gardena Irrigation Control Select
How long does the battery last if it irrigates for half an hour a day?
The 9V battery lasts one year if it is a good quality battery. It has no influence on how long you irrigate.
It also depends on the quality of the battery. In our case, the battery lasts the whole year. We remove the battery over the winter, but it is not completely empty and can be used for a few more weeks in the spring. 🙂
