    My Scooba couldn’t even last long enough to clean my kitchen anymore. This replacement battery did the trick. No issues with this being a 3rd party battery!

    This company was very easy to work with. The first battery they sent me, did not work. But I think it was more my Scooba then the battery they sent. I wanted to return it, and throw my Scooba away, but this company instead sent me another battery to try. The first time I charged the new battery, it did not work. However I charged it again and tried it one more time and it worked, and it is still working. Thank you so much! Great company!

    so far so good, completed a full mop cycle and no issues, will update as to the life of the battery, but so far works like the original

    I thought I could charge them and store them for use on the Scooba. But even if the batter is fully charged, the moment is removed from the Scooba, the Scooba will need to recharge the same batter for a preset charging time before it lets you run the Scooba.

Shipped fast and easy. Perfect fit. Thank you Mighty Max.
Nice replacement, same size, nicely packaged and fast delivery
Purchased two batteries ML9-12 SLA for a Cyberpower unit CP1500AVRLCD to replace old/exhausted OEM batts. The new ones were easy to replace and are a direct replacement and perfect fit of the OEM batts
product showed up in two days and they were fine condition.
I ordered a battery through Walmart online. My mother ordered it for me. It came in 3 days. It started right up. It made my 150 cc moped run so smooth.
Ordered via Amazon on 12/3/2025; arrived in 3 days.
Easy installation and charging as I am typing. Replacing in unit as shown.
