    This battery does not work. The Roomba says charging error. Do not buy. I believe the reviews are a scam.

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.
