    I just installed the battery on my alarm system and thought it might be defective. It wasn?t as my system needed a few hours to recognize it was a new fully charged battery. Very happy w battery!

    After 10 years our alarm system battery died. We researched the Mighty Max Battery and decided to pick it…buying thru saved us some $$$$ and my husband was able to install it very quickly.

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.
