Good battery
Last battery swelled up, emailed immediately, and they sent a replacement right out
Ordered and received in two days. Installed in my generator, it started immediately.
Starts perfect. Great deal shipped fast Amazon delivery.
Purchased 4 of the ML9-12 batteries for my Opti-UPS 1440PS. The batteries are a great fit for the UPS and are very reliable.
I bought the same battery mighty Max 10 years ago for my jump pack- it’s lasted this long. I decided as a precautionary to replace it. homedepot.com. I received it within three days right to my door.
Great battery. Perfect fit for my Honda EM6500SX Generator. Exact fit on the installation. Added a battery tender trickle charge to maintain the battery in a ready state to start the generator. Love that it is made in the USA.
Exact fit to my generator. Came real fast.
Delivered next day and works great
Perfect upgrade for 2007 Mule 610. Sealed lead acid, maintenance free. Great cold cranking amps rating. Replacing a failed lithium “ upgrade “, won’t try that again. Friend recommended it to me. Great price and fast shipping from Amazon. Tested at 12.4 volts upon delivery.
