After getting my car checked at Autozone where they told me that I would need to buy a new battery($ 120+core) and a new alternator($ 134+core). I was referred to Battery X-change for a second opinion, and thank goodness! The owner Hector Terrones was efficient, helpful, and customer service oriented. He told me I didn’t need a new alternator and that I could get a brand new battery from him(that he installed) for just $ 85! Save your money and take your electrical problems to Hector!
