Replacement Battery for Neato XV-21 Battery for Neato XV-11 XV-12 XV-14 XV-15 XV-25, XV Essential, XV Signature Pro, 7.2V 4000mAh (2 Pack)

These only last for 10-15 minutes of cleaning. Don't waste your money on them and purchase the real batteries.I have purchased two off brand versions and been very disappointing both times with the low life span.

Received these batteries last week and much to my disappointmentXV-14 Neato has still not run or I should say move. It starts up but willnot move at all. The screen says it's vision is blocked, followed by thenumber 3000. I've tried the many helpful hints from the company withno results. Has anyone else ever encountered this problem?
