    At about $40 (with tax), this battery is a good buy. The cost of a new Stanley Jump Starter is more than $125 — and they’re not worth it. But, if all you need is a new battery for your unit, this is a choice.Taking apart the Jump Starter can be a trial, even though it only requires the removal of several screws; the screws are recessed, so a long, narrow phillips is needed. I’d recommend magnetizing the screwdriver. Once the unit is open, it’s a simple matter of undoing the leads from the battery and replacing it with the new battery. Worth 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.
