This is the basic operation of any Stand-By Battery service which is exactly what, UPS, utilities, and telephone companies use on their battery plants. It is the kindest most gentle charger there is and provides the maximum battery life. It only has one disadvantage of being slow to recharge. A 3-stage from dead to full is around 16 hours with a C/10 charge current. Float with C/10 will be around 20 to 24 hours.
Note Telcos, utilities, and UPS use much higher charge currents in excess of 1C. But they do not use the same kind of batteries you do.
