Questions about this item

Does the FYIOGXG 2000mAh 7.20Wh battery come with tools or adhesive, or must I buy them separately?

The box contains only the replacement battery pack; no tools, adhesive strips or screws are included, so you will need to source a small Phillips screwdriver and any required adhesive yourself.

My Braava Jet is a model 244 — will the BC674 3.6V pack fit, or do I need a different version?

This pack is listed as compatible with Braava Jet 240, 241, 244, 245 and the Braava Jet Mopping Robot, and replaces iRobot part numbers 4446040 and BC674, so the 244 is covered.

What does the 7.20Wh rating actually deliver in a real Braava Jet cleaning run?

At 3.6 volts and 2000mAh the pack stores 7.20Wh, which typically restores the robot to its original run time of roughly one full mopping cycle per charge.
