Battery FAQs


What are common mistakes when jumping a car?

The most common error is reversing the jumper cables-always connect red to positive and black to negative. Using low-quality cables, letting clips touch, or jumping a battery with visible damage can cause serious electrical damage. When in doubt, have Dennis Hall's Auto Service perform the jump safely.

What should I be careful of when replacing a car battery?

When replacing a car battery, avoid touching both terminals with the same tool-it can cause a short. Don't drop the battery or reconnect cables before it's securely in place. If you're unsure, let our technicians handle your car battery replacement professionally.

Car Starting FAQs


How do I unlock a locked steering wheel?

Press the brake and gently turn the wheel in the direction it moves slightly while turning the key. This relieves pressure in the column and allows the wheel to unlock. Never force it-if the battery is dead or the key won't turn, consult a professional technician.

What does a failing starter sound like?

Common sounds include a single click, grinding, or even silence when turning the key. These signs often indicate a starter issue that requires immediate inspection and service.

I took my 93 Nissan to Dennis Hall back in March because it was idling rough and had them go ahead and do a rear end service on it as well. They did great work and at an adorable price. It is now August and I noticed it looked like my rear end had leaked a little bit and called them to see if I need to schedule an appointment to get it looked at again. They told me to just stop by and they would check it out free of charge to make sure everything still seemed correct. They got me in and out quickly and very pleased they took the time to make sure their work was correct and didn't make me have to pay for another service. I will be going back for all my vehicle needs 10/10 auto shop!

Had an issue pop up when we were traveling on the interstate. We stopped here and they helped us out super quick and were very nice. If I lived in town this would be my mechanic.
