The battery on my 2007 John Deere Z225 mower was failing, so I looked around for a replacement. I found the Mighty Max battery on Walmart's website along with it being sold on several other sites. The reviews I read on various sites were very positive.
The battery was not in store at my local Walmart, so I ordered it through them on line. I figure I can recycle my old battery there.
My new battery arrived in just a couple days via FedEx in perfect condition. It was fully charged and included new terminal bolts. It fit into the mower correctly and performs as expected. I would purchase again and recommend.

Great batteries, easy to install and last longer than over an hour than the original batteries. Very happy with the batteries on my son’s MX650.

Received my battery in 2 days after ordering and it arrived well packaged. The battery seems solid, my Nissan Rogue started right up with no issues and even better the price was perfect, i didn'twant to spwnd over $200 for a battery so this worked out great. Will see in a few months how well it holds up.
