    Battery arrived early and was packaged well. Came fully charged. I researched a few manufacturers and visited the Mighty Max website before finally selecting this product. So far, I’m pleased. I have an old Coleman rechargeable spotlight that gave years of wonderful service. I was sad when the battery finally gave out and didn’t want to throw it away. After doing research and realizing the low cost of a replacement battery, I ordered this one and I’m glad I did. Hopefully, I’ll get many more years out of this spotlight (unless the little electronic circuit board goes bad). For now, spending $10 to revive a 15 year old but very handy spotlight seems like a bargain. I’ll update the review in the future if necessary but for now, I’m a very satisfied customer!

    Perfect replacement for my rechargeable spotlight. Dimensions and anode placement were exact. Charges quickly, and the price is right.

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.
