Review on 🔋 HQRP 3500mAh Extended Battery for iROBOT Scooba 330/350/380/390/590/5806/5910/5920/5940/5950/34001 Series APS 14904 Replacement + Coaster by Cody Unruh

item dispatched and delivered to my door quickly. According to others, this battery worked well as soon as it was taken out of the box. It went through a full cleaning cycle with my Scooba 330 and still had plenty of charge left. After a full charge it went through 2 full cleaning cycles and I think there would have been no issues with the 3rd cleaning cycle. I can't vouch for other replacement batteries, but this $40 battery is worth the price.
