Great batteries and great service!

Best deep cycle batteries I’ve ever bought for my trolling motor! I’ve had all the top of the line batteries and the challenger batteries will give those batteries a run for their money and at 2/2 the cost. Will not buy another battery for anywhere else !

Very nice and knowledgeable guys!! Good products, highly recommend!

Brad is great human being! Very knowledgeable and friendly! He spliced in a new connector for our alternator and told me to spend the money on my wife and kids rather than pay him!

The best. Wont go anywhere else.

When asking where I should purchase a new battery, Challenger came up 2 times. I took my car there and received excellent customer service. My battery was professionally installed in a short time and I was on the road! Great people, I definitely recommend them! Awesome place and great prices! Exceeded my expectations!!

Needed a new battery. They were very nice and took care of it right away- literally within minutes upon arrival. Highly recommend!!!

Went to Challenger on the recommendation of a coworker. It was a good choice! In and out in 15 minutes with an AC Delco battery, cheaper than anywhere else I looked. Awesome customer service from friendly, knowledgeable folks.

Cant beat the outstanding service and products! Reliable, great customer service and a pleasure to work with. Always recommend them when I have the chance. This is the way one needs to experience from all businesses! Been going to them for over 40 years.The guys are great, just like family!

Great service. Able to test battery, recommend course of action, and install quickly.

If I could give Challenger Battery Service 6 stars I would. Just had my 10yr old AC Delco battery from a Silverado replaced by Fred with another one. I was in and out in 20 minutes for a very, very reasonable price! If you live or work even remotely close to them and need a battery, this is your place. I was a first time customer and will be back for any battery needs!

Very helpful, willing to go above and beyond. Just nice folks. Great place for RV battery help.

Very fast service for a new battery. When I thought the battery failed they checked it for free and told me what the real problem was! Thank you Challenger!!
