    So far so good. No issues other than I order the wrong terminal size. My fault. Just had to change one of the connectors. Bought this to replace a bad battery in an emergency light. It’s back up and working correctly now.4 stars because I don’t know yet about longevity.

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.
