What the Pros Say
"I put Interstates in customers' cars because I don't want to see them back in a month with a no-start. They're reliable, the warranty is solid, and they just work, which means fewer comebacks for the shop."
M
Mike Johnson
auto-repair Technician, 15 years"For most daily drivers, a quality brand like Interstate or DieHard Gold offers the best balance of price and longevity. When a customer has a vehicle with start-stop technology or a lot of aftermarket electronics, we always recommend a high-performance AGM battery like an Optima."
S
Sarah Chen
Service Manager"With today's cars full of modules and sensors, stable voltage is critical. A cheap battery can cause bizarre electrical gremlins. An AGM battery from a top brand is essential for handling the high electrical load and deep cycling of modern vehicles."
C
Carlos Rodriguez
Master Technician"Our shop's reputation is built on trust. We partner with suppliers like Interstate because they provide a quality product consistently. That means fewer warranty claims and happier customers who feel confident in our repairs."
