Came in and was helped by Les . Was fast putting in my new battery and helped me put my new key fob batteries in. Super nice people .Owner even cracked a joke with me . Highly recommend master battery on Callahan ! Also I got new batteries for 85$ special today only
Had a dead battery and these guys got right on it and had a Jaguar battery in stock. Walked me through how to get into the hatch and get me back up and running in no time. Highly recommend these guys.
Mike (Manager) contacted me in regards to an earlier review. He invited me to an in-person conversation, took the time to go into details and then asked me to continue being their customer. Very cordial! I will continue doing business with them. Thanks Mike!
The white dude told me the battery included the 5 year warranty. They failed to mentioned it cost an extra 20%. I didn’t notice that they charged me extra until I saw the receipt . That is misleading and there is a reason why people are asked if they want to pay extra for an extended warranty.
years ago they offered good value on batteries, but like all companies that get bought out by big companies previous owner gets rich customers get higher prices. you can buy as good or better batteries for lower prices. pretty store and nicely uniformed employees, but no good prices anymore.
Prices beat most competitors. Unfortunately, for whatever reason, their payment system is antiquated and does not allow for "split" payments (cash & card). Obviously, it's not their fault if you're not prepared to pay for everything via one tender or card. However, considering that pretty much anywhere else in God's America can accept split payments — I just expect an establishment of this caliber to be able to do so. You wouldn't encounter this inconvenience until you have already driven there and stood in line thinking you're leaving with a new battery.
Please upgrade your payment system. It's 2025.
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.
Never go here at this location. The general manager Mike Hammond try’s to start arguments when you’re being nice. I was on the phone he kept butting in on my conversation when I was on the phone. And also after taking 20 to 25 mins refuse to sell me a battery. And being very rude. He works with the public and that not a way to talk to a customer at all. Very disrespectful.
I bought a 3 year warranty battery in May 2024, it's August 2024 now , I went to my car and it wouldn't start I called AAA they came out checked it said my alternator and was good that it was my battery it was dead only 2 amps and 84. So I took it to master battery and they said it was good to to it to a garage so I took it to my Mechanic he said my alternate starter was ok it was my battery 2amps 84 . Master battery still refuse to change it put so I got my mechanic to install another one it was a diehard it started right up. I don't recommend master battery to anyone .
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.
Had never owned a recondition battery in my life. Found myself needing one with my budget was tight about four years ago and purchased one here. Since then, I've never gone anywhere else for any type of vehicular battery. These guys are great!
Quick, convenient, honest, and woman friendly (which seems to be hard to find in this area) . After a morning of searching for a battery and being price gouged from local auto stores for $300+, we called master battery and Dusty was very kind and helpful. Replaced my battery so quick and educated me on my warranties. Will 1000% suggest them to anyone who was in the same position I was!
Phenomenal customer service!!! I was struggling to find a weird battery and the didn't have the exact one, only difference was the battery was wrapped. They wrapped the battery for me and I was out in less then 7 mins!!! Great atmosphere and more then kind people
Came in not sure if my alternator or battery was bad. the gentleman that helped me was so kind. I wish I would have caught his name. but he had tested it. Reassured me that my alternator was fine. and showed me that my battery was dropping very quick when turned off. Offered me a new and used battery. Did not try to upsell me (due to a Budget that was great) He installed it and had me in and out of here and under 10 minutes. Excellent service at this location.
Bought a battery for my Chevy G20 Conversion Van over a year ago and the thing still fires right up for me. That's why I'm going back to them today to get a battery for my Buick lacrosse. Good people. Good service. Good business. I highly recommend.
We went in to check out our battery. Dusty tested it and yes, it needed to be replaced. When he asked the age of it - we told him and even though we got the battery at Honda he thought we should call and see if it was under warranty. We did- it was! He lost this sale because of his advice, but gained our respect and recommendations to everyone for any battery needs in the future. Amazing!!! Ethics beyond compare. Thank you again.
Went to valvoline for an oil change and was told my battery was bad and about to go out. We were referred to Master Battery by our mechanic. We went in and asked for them to check our battery and that we may need to purchase one. They checked our battery and told us it was in perfect condition. The honesty these people have is amazing. Some places will tell you anything just to get a dollar. Thank you Master Battery for your honesty. We will be back whenever it is time for a new battery!
Big Thank You to the folks at Master Battery on Callahan Rd. John was terrific!! He gave me a great lesson on 6 volt battery maintenance in a way that was easy to understand and informative all at the same time. I have purchased several batteries here over the years and the service is always outstanding. Thanks for being in the neighborhood!!
