    I used this Battery as upgrade to original stop and start Volvo S60 battery connection are the same only this battery little higher and support bracket is not fitting, as handy man i made new one. Battery is secure in place it is on and working great. I’m satisfy with this upgrade. Before I purchase this i went to local Interstate battery store, they had one with higher Amp, but the price was more, and original Volvo is double the price with lower Amp. Also, in the past I bought the mighty max motorcycle, size was exact, Amp was the same as Volvo, but connection is different, now I decide to go with this one price wise is double then the motorcycle, but I think wort it.

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.
