My experience with master battery was amazing ! I was helped by a man named Jared and he was so polite and attentive and helped me swiftly and efficiently!! He actually took his time with helping me instead of trying to rush me out the door like all other places were. Highly recommend Jared if you stop by here! Plus their prices can’t be beat!

If you are in need of a car battery, go to Master Battery!! I bought my battery from Master Battery 2 or 3 years ago. I thought it was going bad, so I took my car to one of the retail chain auto parts stores to have it tested. Their diagnostic tool showed everything being ok, but the person didn't seem confident, so I called Master Battery. I explained to the person that answered the phone (Jared) what was going on and he said just bring my car in and let them take a look as their diagnostic equipment was more advanced. When I got to the store, Geoff and another man (I didn’t get his name) were behind the counter, and were both very nice. I told them I had called earlier and spoken to Jared. Geoff grabbed their diagnostic machine and while he was checking my car, Jared came out as well. After a few minutes they determined that I did actually need a new battery. The one I had purchased there previously was recycled and only had a 60 day warranty. I could get another recycled one, or I could get a new one with a 3 year warranty. When I was at the chain store, they said the cheapest battery they had was $199. A new battery at Master Battery was $99. They are currently having a canned food drive and if you bring in 5 cans of food, you can get a $25 discount, so they were able to help me bring the cost down a little bit with that. They also told me to keep an eye on a couple of other things based on their diagnostic test. The whole process was quick, and I was in and out in about half an hour. Geoff and Jared both were very friendly, knowledgeable, and kind. They were also fun to talk to. Needless to say, the customer service was great. Master Battery offers other battery products as well, not just for cars. After two experiences with this store, I highly recommend them and I will always go back to them for any future battery needs.

Dusty was excellent .Great customer service and knowledgeable. I sure hope Master Battery is paying him and the other guys properly. I have seen it to many times where employees are not taken care of and end up leaving.
