Roomba Vacuum Battery Removal and Cell Replacement

We had an iRobot Roomba 890 vacuum with a bad battery. We elected to replace the four 18650 cells inside rather than pay $80+ for a genuine replacement or try our luck with a cheap aftermarket battery with a heavily-inflated claimed capacity. This is a model 1800 which fits various 600, 800, and 900 series Roombas.

Do not attempt to repair any battery unless you are experienced and comfortable with electronics, and understand the risk. Even if properly handled and assembled, a lithium ion battery can still result in FIERY DEATH.
