Amazing and prompt service. I went to another place and was told it would be a 3 hour wait. Came here and waited 15 min. Everyone was extremely nice and friendly and helpful! Highly recommend!!


Master Battery is a worth while place to go to for batteries, flashlights, etc. I had to get a car battery quickly. One of the employees tested my old battery, took it out, and put the new one in. It took less than 30 minutes and I was on my way. Way to go, Master Battery!

Looking for a new or used battery at a great price. Try Master Battery had the battery I needed and put it on hold for me until I got off work. Great service.


I had no idea you could buy and sell used car batteries, but this place exists! I needed two large batteries for a very big truck that were going to cost me hundreds. This place got me going at only 75 dollars for both. I would recommend them for smaller car batteries and for motorcycle batteries as well. They even come out to the car and help bring in the old ones and bring the new ones out to you.

“Store is very visible from the highway. The facility is kept very clean and well organized. Active battery storage area is well ventilated per building code. Sales personnel are very knowledgeable in all batteries that are in stock. Batteries not in stock will be ordered per customers request and a quick turn around time is available. Sales personnel are well groomed and courteous.”

Super friendly staff! Super affordable products! We will be back when we need another battery!

Deals on high quality batteries. Though it seems like a commercial/ industrial shop, they actually have great deals on passenger car and truck batteries.

I have bought 3 batteries here. They always had the exact battery that I needed. I bought a new battery for my RV, and after 6 months, and only one cross country trip to Colorado and back, it stopped holding a charge. I had lost the receipt. I took it back anyway, and there was no problem. They apologized, and replaced it with a new one at no charge. After putting on their tester, they said it was obvious that it was bad. I expected to have to pay a proration charge, but they said no, if it goes bad within the first year, there’s no charge. This is a great business.
