I bought a new Everstart maxx battery at Wal-Mart in May of 2017.Had 5year replacement,3 from Wal-Mart(which owns Everstart) and the last 2 years pro-rated by the company.I tried to get a battery (knowing it was going to cost something)and low-an-behold,the woman at the service desk said it was previously returned and I HAD to have returned it once before. I asked how I could have done that when I had the old one sitting right in my buggy?Just keep your receipt if you buy one.
