I ordered a battery from these guys 2 years ago, with a 3-year warranty for my ATV. Two weeks ago i went out to start my ATV and the battery was dead as could be. Well as warranties go I thought here we go i would not get this battery replaced under the warranty. Well, let me tell you Bigtime Battery was great. They put a replacement in the mail the next day after I call them, US mail two-day priority. Well of course it got lost in the mail. After a week I called them back up, told them I had not received the battery. They FedEx me one two-day priority. You can not go wrong ordering from these people they stand behind they products.
