This battery runs my 4 year olds battery operated John Deere tractor like a charm. We have used it twice and it hasn't needed to be charged yet. My only complaint is that the casing was broken when we received it from Wal-Mart as an online order. The mail these days seems a little rough getting things transported. It is not the only thing that I have ordered recently that has been banged up when I received it. Also, this battery needs a NOTICE written on it or on an info sheet when it is shipped to you that you need to let the battery completely run down before you charge it. It must hold a memory because the battery that came with the tractor, identical to the Preg-Pergo battery that I purchased, lasted for about a year. I found out later that keeping it plugged into the charger was what ruined it. Info I could have used a year ago needless to say. Hope this review helps. I find reviews very helpful when I am ordering online. Thanks to everyone that leaves great tips, advice and information on products!
