Downtown Cleveland battery service
Cleveland winters are hard on batteries, and nothing ruins a morning like a car that will not start. Whether your battery is slow to crank, your dashboard lights are dim, or your car is completely dead, our shop in the bottom of the Hamilton Garage at Hamilton & East 12th can test it fast and get you going again, often the same day. We carry batteries that fit most makes and models right here.
A no-start is not always the battery. A failing alternator or a worn starter can leave you stranded too, so we test the whole charging system to find the real cause instead of just selling you a battery. Our ASE-certified team installs quality parts, backs qualifying new parts with our Fixed for Life warranty, and gets you back on the road quickly. Straight answers, fair pricing and no upsell.
What we do
Everything your battery and charging system need under one roof at the base of the Hamilton Garage, from a free battery test to a full alternator replacement, handled while you work downtown.

Car died on a Saturday and was displaying a battery light. I found Rad Air, called first thing Monday morning and Paul said bring it in. Same day, they diagnosed and fixed the alternator issue, and gave me a three year warranty to boot! Very reasonable and none of the dealer runaround. Highly recommend.
They were able to replace my dead battery same day and were helpful and communicative the whole process. Paul was very helpful.
Really helped me out. We were on a family trip to Cleveland and after a walk our van would not start. I called Rad Air and they had a battery that would work. I walked to the shop and they gave me a ride back to my van, which was really nice. Great customer service.
Our family had an unexpected situation where our battery and alternator broke during a family trip, and Rad Air was able to provide fast and affordable repairs to get us back on the road home.
My car needed repair after I was away for 6 months, and Paul did a great job helping me replace the battery and clean my car. Fast and outstanding service.
Fast service and transparent pricing. Definitely going to be heading back there next time my car needs work!
Paul and team were amazing! Excellent customer service and professional work. I highly recommend them!
Reliable, friendly and honest! I tried other shops in the area before coming to Rad Air and I wish I had just started here first. I will keep coming back!
Paul and his team are excellent to work with. They were clear with what they found, providing an estimate and completing the work quickly. Great job!
They always get work done in a timely manner. Prices are reasonable as well. The manager is very helpful and makes the entire process very easy. Highly recommend coming here!
From the time I dropped my car off I felt I was in good hands. When it was explained what was needed and why, I was confident in what I was told. I have no complaints and will return if another concern arises.
Paul and his team have always been professional, prompt and transparent. The location and convenience cannot be beat, and they have always treated me right, never pushing for unnecessary add-ons or repairs like some shops do.
