10 year old Roomba model 560
Original battery quit about 5 years back...replaced it with an extended life battery.
That replacement was only lasting about a half hour of running lately, so I went to Amazon and bought a Lithium Ion battery. Now, it runs better and longer (almost 3 hours)
The Roomba has a new life again.
