Once in a while after use (and a quick find of the home base) the Roomba will have a charging issue. I have figured out that since this battery holds more power than the normal battery and that: -If the Roomba quickly finds the home base it comes up with a (delayed) charging error. -If the Roomba does not find the charging base quickly, it spends more time cleaning and then does not have the charging error.
Solutions to correct the charging error: -A second cleaning cycle will overcome this charging issue. -Directly connecting the power cord into the Roomba will also charge it back to normal.
