A dead truck battery does not wait for business hours. We bring commercial-grade Group 31 and 4D batteries directly to your location in Austin, Hutto, Georgetown and surrounding Texas — and replace them on the spot, day or night.
Battery problems often develop gradually before a complete failure. Know these warning signs so you can act before you are stranded.
Engine cranks slowly or fails to crank at all
Electrical accessories dim or flicker when starting
Battery warning light illuminated on the dashboard
Battery requires jump starts more than once per week
Swollen or leaking battery case
Visible corrosion buildup on battery terminals
Battery is 3+ years old in heavy-duty commercial use
Commercial truck batteries are not auto parts store items — they are high-capacity Group 31 or 4D units designed for the extreme demands of diesel starting and long-haul electrical loads. We carry commercial-grade batteries rated for dual and quad configurations and replace them at your location without dragging your truck to a shop.
We test your existing batteries under load before recommending replacement. A bad cell in one battery can drain the entire system — we find the culprit accurately before any parts are ordered.
Texas Heat Warning: Austin summers regularly exceed 105°F. Extreme heat is the leading cause of commercial battery failure — it accelerates internal corrosion and plate warping. Have your batteries tested before summer if they are 2+ years old.
Need a jump right now? We carry professional heavy-duty commercial jump packs capable of starting any diesel engine in our service area. Jump start service is available immediately, 24/7.
If your batteries keep dying after being jumped, the problem is usually the alternator. We test charging system output — voltage and amperage under load — on-site and can diagnose alternator failure without moving the truck. Rebuilt and new Delco-Remy and Leece-Neville alternators are carried for the most common heavy-duty configurations.
