Battery works well and is a perfect replacement in the Zoozee Z50 vacuum cleaner.

Works perfectly to replace battery on the Coredy rumba vacuum!

Working good

So far so good the battery came in the level was a little low. I guess that’s normal. We don’t know but we charged it up. It went to 100% and then everything looks good. (Old battery) The old battery was no longer functioning when the robot left the docking station it immediately died. (New battery ) Currently the battery is charged to 100% and working the vacuum thank you if anything changes will update the review.

Seemed to have solved my issue in my lil robot vac.

I have an Zoozee Z50 after 2 years it was not holding a charge. Replaced battery and works like new. Now my Zoozee Z50 has been running non-stop for over an hour!!!! Thanks!!!!

Considering the size, this is stronger than some other batteries. The output voltage is rather high and may not work on some 12V devices. The quality looks decent so far.

Works as described. Good power/voltage and capacity/runtime. Easy installation and was pre-charged on arrival.

I replaced my old one. So far so good

Fit perfectly
