Ether,
This recommendation is a poor man's fix to get around leaving the battery connected to a smart charger. The smart chargers generally turn off once full charge is reached and won't restart until power is removed or the battery is disconnected and reconnected. The general practice of topping off the charge every couple of months is then simulated every 24 hours. Light timers that allow turning devices on once a week is a better substitute as long as they are non-dimming types. Not stated yet is to store batteries where they won't be subject to temperature extremes particularly preventing freezing or temperatures above 100 degrees. In other words don't store them in a garage or shed.
