    Battery arrived sooner than promised. I removed the old battery and replaced with this one with ease on my own (I?m 54 years young)!Just have to figure out how to dispose my old battery? Any ideas?My security company charged me @$100 or so the last time they replaced my battery. Why? It takes less than 10 minutes to remove the old and replace.You can do it yourself and save $$$

    I ordered two Mighty Max Batts. of different sizes, one for my garage door and the other for my house alarm system. I have them installed for a few weeks now so I can’t comment on the longevity but so far I like the batteries. Packaging was efficient and protecting and Batts. measured correct voltages so far I’m a happy customer.

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.
