    I bought this to replace the battery in my Cen-Tech 3 in 1 jump starter. It fit and was easy to swap out.

    Received exactly what was described by seller. Good price and product arrived on time. I’ve already bought four of these batteries and they’ve saved me a ton of money . It would have been very costly to replace these car jumpers if I hadn’t found the batteries. They were simple to install.

    When you need to replace your battery in a Jump box battery charger, make sure you get the right size and that is the problem with your charger. This worked for me

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.
