Review on Dutyone 3000mAh Replacement Battery for Neato Botvac 12V Series and Botvac D Series Neato Battery - Compatible with Neato Botvac 70e, 75, 80, 85 Robot Vacuum Cleaners - Ni-Mh 12Volt Battery by Jennifer Redmond

If the allotted cleaning area is small enough to finish for a charge time without stopping, this battery pack will do. However, in my case, the battery dies before it runs out and I have to go home to charge it. The original battery and the first replacement battery had 25 and 20 percent more ampere-hour capacity (4000 and 3600 mAh, respectively) and got the job done without a recharge cycle.
