I cannot agree with the suggestion that it flattens the battery more to leave the unit turned off. These are lithium primary cells with a shelf life of well in excess of 10 years. In other words, if you don't take any current from them, in 10 years they still have significant power left in them. If you discharge some power from the battery then once it's gone, it's gone - the lifetime will reduce. All the manufacturers' data I have on lithium primary cells supports this view. If the backup batteries were lithium ion or lithium polymer secondary cells then the answer may be different. Keith.
