Replacement Battery for iRobot Roomba 690?

Hey Fixers,

I am looking for the replacement battery for the iRobot Roomba 690. The iFixit site has a battery for the 691, but I’m not sure if it’s the same format since the 691 originally spec’d to have a 60 minute runtime and the 690 has a 90 minute runtime.

Does anyone know if the iFixit battery is the same as the 90 minute Li-ion from iRobot? Thanks!
