Did not expect the receipt of a battery that fast was impressed. A perfect clone for the bad one in the vehicle. Price was very comparable, would definitely order again if needed.
Great product also love the free extended warranty. I replace the dead battery on my moped started right up.
Easy delivery from Amazon. Fit right into my hustler 60 inch.
Good battery right out of the box
Just replaced the battery in my ups unit and it was a piece of cake to do.
Purchased on eBay and arrived just over 24 hours. Awesome! Using 6 total for 3 UPS’s that needed new batteries.
Great Batteries
Bought for snowmobile came quick will snow tomorrow
Correct replacement for garage door opener. Shows only half charged so will have to see if the garage door opener keeps it charged.
Arrived right on time. The packaging provided excellent protection during shipping. All the information and items we need to use this in a Minnie Mouse quad was included.
