Excellent service and great inventory of batteries and their needed products.

Just stopped in paid for my truck battery after they installed it. Awesome job and awesome customer service. Highly recommend this place.

Honest & friendly all American Business! Extremely competent with fast service.

Very helpful sales staffI went here to purchaseNew batterys for Bernadettes Handycapped scooter. They helped me pick out the strongest gell battery that cant leak and holds a longer charge they have the batteries and supplies for your and any power supplies you may need I highly recommend this supply company

Love the service there. They take care of you quickly and efficiently. Very knowledgeable and friendly. I highly recommend them for your battery needs.

Two guys in there were extremely helpful and some of the funniest people I met. If I could rate higher I would.

Didnt know I was getting entertainment with my battery change lol. Owner and colleague so friendly and funny, was in and out in 5 minutes.

I highly recommend this Battery One location. Ive been there several times and always get prompt, pleasant and helpful service!

I went in this morning to buy a battery for my bike. Larry and the rest of the team were an absolute pleasure to start my day with, thanks guys!

Battery 1 is my go-to for my battery needs. They have been great for 20 years, for boating, camping and automotive needs.

Staff were professional and efficient.

Battery One beats Costco in four ways.I have bought batteries from Battery One for years. Always happy with results. I am otherwise a loyal and happy customer of Costco for all kinds of things so I decided to make two phone calls. I got a quote from Costco and Battery One for my 2015 Volvo. Battery One quoted 40% less and provided a longer warranty. Battery One replaces battery in car for free. Costco hands you the battery for you to install.So once again, I went to Battery One and was quickly told if the Low Battery message came to the dash, it was most likely the key fob. They checked both and the key fob needed two nickel sized batteries. The main car battery was fine. They replaced the fob batteries for just the cost of the batteries.If I had gone to Costco, I would have removed the battery from the car to get the core-charge refund and either bought a new unneeded car battery, or had them check it only to reinstalled the same battery back it the Volvo. Hopefully Costco would have figured out that I only need a key fob battery, but based on my phone call to get a quote, I doubt it.

Battery One is THE BOMB!! In and out with a new battery in 15 minutes. Dude just came out in the parking lot, pulled out the old one and put in the new one. It was almost like a drive through. Did I mention best price in town too!!

If you need any battery this is your place (exception for laptops- these will have to be special order). They will test and diagnose the condition of your battery in any vehicle or device before selling a replacement. They will also install the battery while you wait (if Too busy and too tired. Hey, dont all of you get in the water at once. The rising level is already an issue along the shore.) with no additional charge. Close to downtown Frederick with free parking.

Very impressed with the honesty and integrity of this little shop. My truck is 6 years old and with the recent cold temps I was worried that it was finally time for a new battery. I went by last night expecting to have to make a purchase. The gentleman came out and checked my battery and said I was still good to go. They could have easily sold me a new battery even though I didnt actually need it. I will definitely be back when the time is right and will recommend to friends and co-workers. BTW, this is also one of the only places that was willing to do the install of the new battery for me as well. I had called around to check on prices prior to stopping by and Advanced Auto and Auto Zone both told me they would not be able to to the installation of a new battery because of a bracket that would need to be removed. When I called Battery One to get a price they immediately knew about the bracket and told me it would take about 5 extra minutes compared to most vehicles.

They have every battery that you can think of. Great customer service too. Easy in and easy out. Just tell, or show, them what you need. They have it all in stock. I never had a problem fing a common, or weird, battery at this place.

Battery shortages due to pandemic otherwise good service

Great place to get a battery

A cool little Mom and Pops place for a fordable

For years, I changed my own battery. It didnt make sense to pay a mechanic to do it. That is until I found Battery One. For the same price I paid to change my own, they test and change your battery for you. The staff is always friendly, and they warranty the battery.

I was in desperate need of a hard to find camera battery. One call and the owner said he had one. Sadly, it was defective and he called me back to tell me not to start traveling to his store. BUT....he had another at one of the other stores he owned. I got my battery and was surprised they had already started charging it for me. Amazing customer service. They definitely went over and above what many others would have done. Thank you!

Went here to get my car battery replaced. Very quick, friendly service, and the best price I found in the area! A great business, and one Id recommend without hesitation.

My boyfriend and I always come to this place when we need to check on equipment batteries or to buy new ones! These guys are always welcoming and provide excellent customer service!

1st class service. Very knowledgeable and helpful staff. No hesitation recommending them.

They made my positive and negative cables and they came out great! I also bought a deka battery. Great people awesome service!!

A nice little mom and pop battery shop, they will have any battery for a car or truck you need. A little pricey compared to national chain places but you get way better service.

Always outside service and products

Always friendly and courteous. Huge selection too!

Fast, friendly service!

Great shop excellent service. Purchased a motorcycle battery here and they even helpd me install it!

I went to Battery One looking for a battery for my cell phone. Before I went in I checked the prices on ebay, where they had them for as little as $2.90 with free shipping. I didnt want to wait for the battery to come in the mail if I could get it here, and I like to support local business (within reason). Battery one wanted $29 for the same battery. Obviously ebay sellers have volume to their advantage, but not enough to justify being literally ten times more expensive. Im giving them an extra star because they were friendly.

If you need a battery they have it
