VERY honest and nice. Prompt and fair service. I went there with a battery that seemed to be dead to buy a replacement. They didn't want to sell me a new one because they felt they could save it, for FREE! And they did. A month later, a different car of mine had a battery problem. Other Interstate Battery dealers (I was staying with my parents when it happened) tried to take advantage of me and played price games with the warranty and proration. Ace had none of that, having the SAME price for proration, warranty and normal purchase. (The other dealers used a LOWWW price for prorate credit, and a HIGHER than normal price for warranty 'purchase', to the point where it was the same price as buying it outright.) ACE IS THE PLACE FOR BATTERIES AND ELECTRICAL!
