    Works great and it looks good the only minor problem I had was the post for the negative was bent and it needed to be straightened out with pliers.UpdatedThis was left on a battery tender over the winter and I went to start it and it would not do anything the battery is dead and will not hold a charge.Unfortunately I did not make this discovery until 6 days after the warranty expired and when I called them there was nothing they could do about it.I guess I shouldn’t complain about that out of warranty is out of warranty LOL but still wish this battery would have lasted longer than one summer.

    Battery was a perfect fit, started my bike right away after being in storage for 14 months. After a few months this battery still starts the R1 like nothing. Love this battery, I also applied the battery terminal protection after the old battery turned into chaos once I had it in storage.

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.
