Charge lasts 20 minutes and won't finish the job.

I ordered the same replacement battery over a year ago when my Neato wouldn't hold the charge very long and wouldn't clean the whole house. It was like new after the replacement running 45 minutes before recharging. I reordered "same" batteries this week and put them in 2 days ago. It runs for 20 minutes and is worse than before about doing all rooms. Very, very disappointed.
